The end of a large number of idle and wasted to achieve universal mobile phone charger

Recently, the Ministry of Information Industry issued the "mobile phone charger and interface technical requirements and test methods", requiring all cell phone brand charger interface standard of the national unified design universal mobile phone charger. Prior to the introduction of national standards, many mobile phone manufacturers are based primarily on a cell phone charger designed with a tradition of thinking to plan and design products, the same brand of different models of chargers can not be universal, and different models of the inspiron b120 battery, inspiron b130 battery chargers Specifications vary widely, resulting in cell phone charger can not be used interchangeably by a large number of idle and wasted.

According to statistics provided by Ministry of Information Industry show that China's nearly 450 million mobile phone users, an average of 100 million mobile phone users will change, but for different models of mobile phone brands need to use a different charger, which means that there will be a year close to 100 million chargers be eliminated waste. Standards after the introduction, Bird, TCL, Amoi and other domestic brands have said they will in accordance with national requirements, production and compliance mobile phone charger. Bird said that before, have taken the lead within the enterprise to achieve a cell phone charger interface and the harmonization of standards, the charger can be common, the same charger can charge different models of mobile phones. At the same time, due to Bird phones use a standard mini-USB port, so long as to find MP3, digital cameras and other electronic inspiron 1300 battery, hd438, kd186 products, data lines, use it to connect mobile phones and computers, you can achieve the charging and data transfer functions. Moreover, the product is increasingly common parts strong, different models of mobile phone chargers, battery, data cable, hands-free headsets can be common for users to use mobile phones to bring more convenience.

Mobile phone USB charger sought after by the market

In the booming mobile phone industry, driven by mobile phone charger manufacturers remain optimistic about the prospect of the industry. Most companies focus on OEM and ODM business areas. Mobile phone charger FOB prices remain stable, many companies plan to increase overseas shipments. Raw material prices, especially plastics and metals prices.

Mainland China is the world's largest production base for mobile phone latitude d520 battery, latitude d600 battery chargers, with more than 100 mobile phone charger manufacturers, most of them small and medium companies. The average monthly capacity of each manufacturer for more than 600,000, most of these companies also produce other cell phone accessories, mainly gathered in the Guangdong Province.

Despite the excessive competition led to a number of market decline, expect the Chinese mainland in 2005 total shipments and exports continue to grow. Travel charger and car charger is a mainstream product, the market still appears the desktop and emergency charger product lines such as wealth, including cell phone manufacturers with different connectors universal charger. In addition, China's exports almost all mobile phone charger products CE certified.

Today, USB charger to obtain the market sought after, and with good market prospects. In the HKSAR, the manufacturer provides travel for emergency use and car charger, a number of companies to increase available USB charger. In recent years, oversupply led to Hong Kong's export growth slow down. Manufacturers to focus on research and development to improve product design and increase the form factor in terms of user-friendly, Hong Kong manufacturers in the main aimed latitude d620 battery, inspiron 630m battery at high-end market.

In 2005, Taiwan's mobile phone chargers manufacturers plan to increase production and exports. The supply of cars in Taiwan, travel, USB, emergencies and desktop charger. However, due to increased competition, firms decrease the total number of cases, some manufacturers have already withdrawn from the market.

Battery cell also rose in July, the new universal benefit Shunda

Battery cell raw material prices, driven BP-511 battery prices, Taiwan's Department of battery factory yesterday (24) said that this year will be rising for battery cells in two waves, this month gone up anywhere, but also has another one in July. In addition, the second half of the battery core shortage problem is serious, whether the sources of material to grab the battery core stability, it will be able to dramatically the battery assembly plant growth in revenue key.

Two batteries of domestic assembly plants in the new P (6121) and Shun (3211) yesterday, have said that as the close cooperation with the CR-V3 battery cell maker, battery cell supply will not be a problem, but the second-line plant in the second half is likely to face shortage of supply of .

While the battery cell in prices, but has been completely passed on to the battery pack prices, price increases for some products is also higher than the battery cell increases, the situation on the new Pu, Shunda and other battery plant favorable, traders said that the future would depend on the raw materials for costs continue to adjust prices.

Pu Song Fuxiang be held before the new chairman of France said they would, said that the battery core prices will rise, in fact, the battery core prices have increased this month, a wave, AM about 5% to 8%, due to the battery core materials include cobalt, nickel prices , and the gains almost doubled, and the klic-5001 battery core is expected to hike prices again in July, up 5% to 6%.

Battery cell supply to Japan, South Korea-based manufacturer, which rises in Japanese Sanyo has announced that 5-8%, Samsung SDI was jumped 7% to 10%, while the Japanese giant Sony announced plans starting from next month on the 1st follow-up hike, AM is also around 5-8%.

This year notebook shipments in terms of 9,500 million units, or even could reach 100 million units, the battery core from last year's Sony battery recall incident, continued tight supply, the second half of this year came during the peak season effect, the battery would be great lack of core goods, batteries, EN-EL3e battery assembly plant must master the core source of revenue recorded a chance Suibi increase in PC shipments to grow.

Prices, Wuxi excess production capacity batteries for export face challenges

As mobile phones, digital cameras, camcorders, laptops, electric cars and other consumer products, the continued strength of domestic battery is a lithium-ion batteries in particular, has shown great potential for applications, but also for export provided the impetus for robust growth. As of April 2007, in Wuxi, Jiangsu Province, were exported from the EN-EL4 battery 5116 batches of up to 310 million U.S. dollars export value, compared with the same period last year, an increase of 33.75%, respectively, and 36.78%.

Wuxi region's exports from the terms of types of batteries, lithium-ion battery products accounted for 80% of the total export volume over. In recent years, Sony and Panasonic, respectively set up production base in Wuxi, allowing the export of Wuxi in the Li-12B battery form a strong pull. From the mode of trade point of view, the battery in Wuxi-based exports, mainly to processing, the main exports to the Free Trade Zone and the Hong Kong and Taiwan, as well as Japan, the European Union and the United States. At present, the Wuxi area exports of lithium-ion batteries show the fast-growing momentum at the same time, there also exist some much-needed solution.

First, continued growth in demand, prices continued to decline. Lithium-ion batteries a mature market price to more than 15% average annual rate of decline. The second is excess capacity. Wuxi area the size of the battery industry due to rapid growth of production, have produced an oversupply in the market, leading to falling product prices, affecting economic growth in the industry. As the lithium-ion battery production plans and the upgrading of digital products have a very close relationship, with the digital products continues to introduce new lithium-ion Klic-7004 battery production plans have changed. Third, raw material costs. Since the second half of 2004 has been a sharp rise in world oil prices caused the rise of related chemical materials, particularly polymers. The ordinary chemical material compared to 2003, there are about 50% of the price rise, in which chemical solvents rose more than 70%. This state of affairs led many manufacturing polymer lithium-ion battery production enterprises have to face the issue of rising production costs.

The good news is, at present, the battery plant in Wuxi in new product development and upgrading of the faster, new products accounted for 40% of the total, in the battery industry have a certain competitive advantage. The battery product rational structure, most of them are environmentally friendly batteries, are therefore subject to the impact of the EU Directive pairs of green also less. But battery companies still vigilant. First, we must increase research and development for specialty Minolta NP-500 battery products, some thin battery or larger capacity battery development in order to give full play to polymer lithium-ion battery expertise and advantages.

As the polymer lithium-ion battery, which uses flexible packaging material, the mold shell is relatively simple, low cost, easy-to-change type, can be completely customized to user needs with the production, and timely conversion model, to respond quickly to market demands, in order to thin battery and large-capacity battery to create the conditions for the development. Second, enterprises should actively adopt new materials to reduce production costs or increase battery battery cost. At present, the polymer lithium-ion battery production in the main materials - positive and negative materials, accounting for more than half of the total cost of the battery, the production enterprises should actively explore new techniques and recipes battery such as NB-2LH , NB-4L , NP-20 , NP-30 , NP-BG1, ingredients and processes through the integration of the development of safe and reliable, affordable alternative materials to reduce battery costs, increase market competitiveness.

NB battery battery cell panel supply fault

Fear of the next quarter to reach 20% of the impact of NB(DSLR Battery Grip, Digital Camera Battery) shipments in the second half

In previous years, both key components in the fourth quarter played out drama yards this year, advanced to the second quarter. Notebook computer (NB) on behalf of the factory and components industry pointed out that the panel and battery supply had been tight in the second quarter is estimated batteries battery cell supply fault, in the third quarter to reach 15-20% in the fourth quarter even widened to 20% to 25%, fear will affect the NB shipments in the second half.

This year the global notebook shipments estimated at 9,500 million units to 100 million units Nikon D60 Battery Grip, compared with last year's growth of about 35%. Parts and components industry, said the first half of Microsoft Vista is not yet apparent effect of driving a large number of growth will be concentrated in the third quarter and fourth quarter, but key components in short supply, fear will affect full-year shipment growth rate.

Some notebook computers in the fourth quarter of serious shortage of key components, including lithium batteries, processors, dynamic random access memory (DRAM) are from the third quarter of last year's supply in an emergency, so that the brand makers, including Hewlett-Packard, Acer, are focused their attention on supply, even from the second quarter of this year's shortage began to appear, in particular, those firms with Dell's market share to Hewlett-Packard, have long focused their attention on the extent and smooth Nikon D80 Battery Grip supply of components, to avoid affecting the result of market share decline in shipments.

Parts and components industry said that this year out of stock parts and components mainly in the panel and lithium battery. Grasp the global notebook PC shipments up 47% over the two systems factory Quanta, Compal, recently said that he would, when in France, have pointed out that the panel will be out in the second half. Quanta President China pointed out that this notebook computer in Vista and Santa Rosa, driven by shipments of optimism, but the worry is that LCD panels may be out of stock.

Compal, general manager of Ray Chen said that this year to increase LCD TV production to drive prices, panel plant transfer, and it gets so small and medium-size panels, supply situation is no longer smooth, over the past notebook panel order is on call, However, early this year have to plan Nikon D90 Battery Grip production, forecast in the third quarter will be even more severe shortages.

Similarly, a serious shortage of key components, as well as lithium batteries. The battery industry pointed out that out because same as last year, are both large-scale Sony battery recall last year's follow-up impact. The four major battery cell suppliers: Sanyo, Samsung supply a slight increase, but the supply of flat Panasonic, Sony reduced the supply of the whole, from the second quarter of supply has been tight.

Battery technology abroad Communication Research

Communication as a communication system with battery back-up means of energy supply, the development, production and application of technology the world has been much attention to the telecommunications industry. The current widely used VRLA Battery (VRLA), as a result of the well-known weaknesses and shortcomings, can not adapt to the information age has become increasingly the development of the practical needs of communication. With the technology and the continuous advancement of technology, being developed abroad, and by testing a new generation of communication with the ibm thinkpad r51 battery, and some have entered the commercial stage. These new batteries, because of its materials, structure and technical nature, in the performance of the VRLA battery has an unparalleled tradition of superiority. In this paper, in accordance with the relevant information on the current development of more mature outside of the vanadium battery and polymer lithium-ion batteries Brief Introduction to the beginning of the hope that it can be a source of inspiration domestic and learn from peers.
I, V batteries (Vanadium Redox Battery)
Vanadium battery (VRB) is a mobile battery, the current is gradually entering the commercial stage. VRB as a chemical energy storage technologies, and traditional lead-acid batteries, nickel cadmium batteries as compared to the design of its many unique features, performance is also applicable to a wide range of industry forums, such as an alternative to oil machine, stand - power, etc.. Design and manufacture using the VRB technology VESS system (VanadiumEnergy Storage System, namely, vanadium energy storage system), its design and operation characteristics of the VRB to be based on optimization, and integrated a number of intelligent control and automation for managing the operation of electronic devices . To put it simply, vanadium electrolytic cell will be stored in the wave energy is converted to electrical energy, which is adopted by two different types, separated by a layer of membrane between the vanadium ion exchange of electronic achieved. Electrolyte is a mixture of sulfuric acid and vanadium, and acidity and, as the traditional lead-acid batteries. As a result of this electrochemical reaction is reversible, so the battery can be recharged VRB can discharge. With the two kinds of charge-discharge when the vanadium ion concentration changes, and chemical energy to electrical energy conversion. VRB electrolyte battery and two layers of battery modules. Electrolyte used in two different electrolyte Sheng. Each battery unit by the two "half-unit" of the diaphragm and the intermediate holding the electrode for current collection. Two different "half-unit" in full bloom at different ionic forms of vanadium electrolyte. Electrolyte in each pool with a pump for the closed channel for each of "half-module" electrolyte transport. When the live layer of electrolyte of the battery in a mobile unit, the electronics on the flow to the external circuit, which is the discharge process. When electronic transmission from the external to the internal battery, the opposite occurred in the process, that is, to the electrolyte in the battery charging unit, and then transfer back to the electrolyte by the pool pump. In the VRB, the electrolyte in a number of inter-cell flows, voltage is the voltage of each cell formed in series. Nominal voltage is 1.2V. Current density from the battery unit of surface area collector current decision, but depends on the current supply of electrolyte in the battery unit between the mobile, rather than cell layer itself. VRB cell technology one of the most important characteristics are: peak power depends on the total surface area of the battery level, and battery power consumption will depend on how much electrolyte. In the traditional lead-acid batteries and nickel-fu, the electrodes and electrolyte are placed into a power and energy is strongly dependent on the plate area and the capacity of the electrolyte. VRB batteries but this is not the case, it is not necessarily the electrode and the electrolyte must be one, which means that the stored energy from the battery casing can be restricted. From power on, the different levels of energy for the different cell layers or unit cell group through the provision of adequate electrolyte to get. To charge and discharge the battery level does not necessarily need the same voltage. For example, VRB ibm thinkpad r52 battery level can be used in series battery voltage discharge, and recharge the battery level can be another part of a different voltage.
VRB batteries are used in communications, its obvious advantages:
(1) energy efficient cycle;
(2) the depth of life will not be affected after discharge;
(3) not due to corrosion of the electrolyte affect the chemical properties;
(4) The electrolyte can be used indefinitely (does not address the issue);
(5) cycle life is unlimited (only by the lack of restrictions);
(6) energy storage can be measured accurately;
(7) in use a very small impact on the environment. These characteristics in a wide range of communications applications in the development of DC energy storage system has provided a guarantee.
VESS is integrated with the VRB, a practical energy storage systems. The expert system used in control technology, will enable operations management, capacity management, routine maintenance, error correction processing, system status monitoring and automatic external communications. VESS gave up back-up in the traditional, such as commonly used in energy charge, discharge, concepts such as line voltage, and to store and transfer energy to replace the concept. VESS applications in the communication features of a major: VESS can power existing communications infrastructure to make better use of, and may be considered non-polluting in the new communications applications for the introduction of energy storage infrastructure.
As a single component of energy storage, VESS can just install a wide range of power voltage. With respect to the traditional series of lead-acid or nickel-cadmium batteries, such advantages are significant.
From the storage point of view, this is because:
(1) All the energy stored in the wave of electrolysis;
(2) the power output depends on the electrode (layer) size;
(3) the energy density of the system from the physical storage of energy and system isolation;
(4) stored energy is stable.
Running from the system point of view, this is because:
(1) for each unit are charged with the same state;
(2) The system can charge and discharge at the same time;
(3) lead-acid batteries charge faster than fast;
(4) run-time can have one or more electrical input, and can output a wide range of voltage values;
(5) automatic feature that automatically rectifier and automatic protection.
System maintenance from the point of view, this is because:
(1) can be increased by adding electrolyte to the independent operation of the system time;
(2) energy storage systems can be increased at any time, the cost of only 20% of lead-acid batteries;
(3) long life, 5-10 years just to replace some parts and components;
(4) very little maintenance.
And many traditional secondary battery technology, VRB cost is very competitive, but also before the use of lead-acid ibm thinkpad t42 battery technology that will be very expensive or impossible to achieve a number of applications, now VESS can easily achieve. Therefore, the current DC power supply system, VESS is a very desirable alternative. VESS fuel cells table capacity can only know that the cost of energy storage and very low, so its prospects for communication applications is very attractive. In addition, VESS portable energy storage and the storage and use of independent of each other, so communications applications can be used in specific occasions. Alternative to oil machine. Communications power systems typically use diesel generators to power the driving force for a long time when. When the machine start-up and pre-heating oil, they usually need a battery to provide the driving force for a short period of time. In the communication station is also frequently used by UPS to provide uninterrupted AC and DC uninterruptible power supply, both the need for a separate battery. Some stations I use a battery DC power supply continuous, uninterrupted AC power through the inverter need to be. Backup system machine oil investment in the power system accounted for a large part of, and need continuous maintenance of machinery in order to ensure its reliability. In practice, the utilization of machine oil is very low, so the use of cost per unit time is relatively high. VESS-based system is the new power system has the potential to replace oil in the machine, for the reliability of UPS and DC power provided by the general, multi-functional energy storage solutions. Alternative to solar cells. A number of communications management of the maintenance of a huge, very wide geographical distribution of the solar battery-powered communications network. Solar energy power supply system components are usually lead-acid storage batteries, which requires a lot of maintenance. VE SS has the potential to substitute for solar cells, reduce costs and increase productivity.
In a typical communication applications, and compared to lead-acid batteries, VESS has many advantages;
(1) automatic control provides automatic protection function, automatic rectifier and system control interface;
(2) the internal control unit to control other system components;
(3) energy storage capacity can be accurately read out directly;
(4) long life, the use of 5 years or so, just to replace some parts and components;
(5) energy storage can be added at any time, the cost of only 20% of lead-acid 92p1077 battery, about 200 U.S. dollars / kWh.

The advantages of fuel cells

Fuel cell power generation compared with other unique advantages.

And high efficiency. Without fuel cell power generation from geothermal energy to mechanical energy again to the conversion process, there is no link in the middle of the energy loss. At present, thermal power or nuclear power is the highest efficiency of 40 percent, while the fuel cell power generation efficiency is generally 40% ~ 60%. High melting temperature carbonate and solid electrolyte type fuel cells, emissions of heat can also be used for the second generation. The use of waste heat for heating or combined together for power generation, fuel cell utilization efficiency up to 70% ~ 80%.

Flexibility. Fuel cell power generation device is composed of a number of basic units. A basic unit is a two folder electrolyte electrode plate. The basic unit will be assembled hundreds of them would constitute a battery pack, battery pack and then together to form a power station. Can be flexible depending on the needs of different size to the assembly of fuel cell power plant. The basic unit of fuel cell design standards can carry out large-scale pre-production, so the fuel cell power plant construction and low cost, short construction cycle. In addition, as a result of fuel-cell light weight, small size, high specific power, relatively easy to move up, so it is particularly suitable in remote areas or islands to build power stations, or build a distributed power plant.

Fuel diversity. Although the fuel cell hydrogen is mainly the work of the material, but it can be used for fuel gas, methanol, liquefied petroleum gas and other hydrocarbons. According to the actual situation, in line with local conditions to use a different fuel, or combination of different fuel use, can reach local materials, to save resources.

Pollution-free. The main product of fuel cells is water, essentially non-emission of harmful gases, it is a very clean source of energy. It is reported that a number of fuel cell emissions of harmful gases in the United States national standards for environmental protection by two orders of magnitude lower. In addition, the fuel cell is a stationary power generation, has no mechanical transmission device, only in the control system and other auxiliary devices have moving parts, thus it is the work of a small vibration, low noise.

Due to high cost of fuel cell, generating cost-effective as other methods do not, we can not get the promotion. Therefore, only the cost of significantly reduced and further enhance the service life, fuel cells will enhance their competitiveness. According to the U.S. departments of statistics, when the construction cost of 3 U.S. dollars per watt hours (1994 has reached), the fuel cell will be able to enter the market; when reduced to about 2 U.S. dollars, can be in remote areas as an independent power generating system; When reduced to about one U.S. dollars, the market will expand rapidly. 1 U.S. dollars to achieve this goal, it is necessary to the life of fuel cells will be increased to 40,000 hours.

The development of fuel cells is now very fast speed. In accordance with national plans, by 2000, Japan’s fuel cell power output will be close to 2200 megawatts, the United States will reach 500 megawatts in 2000, Europe will reach 500 ~ 900 MW. By 2010, the world’s total installed capacity of fuel cells will reach 60,000 MW. As a new type of fuel cell energy, is still relatively high cost, long life is not enough, power is still relatively small. However, with the depth of the research work, these problems will be solved. Many scientists believe that the era of knowledge economy in the 21st century, fuel cells will account for in the field of energy in a pivotal position, therefore, have the fourth-generation power technologies, research and development of fuel cells with the significance of the next century.

Dianchi Lake every year 100,000 tons of refuse what way
Dianchi Lake salvage garbage placed where it? Dianchi Lake every day along the flow of garbage to deal with the future, what will? This reporter visited the HKMA Kunming Yunnan, Kunming Environmental Protection Bureau, Kunming sanitation experts monitoring center after that, a massive clean-up campaign refuse Dianchi Lake basin has been fully launched in the next few days, but the inflow of garbage along the Dianchi Lake how to deal with, it is worth exploring one of the new problems.

Refuse disposal sites will be built lake

Kunming, Yunnan Province, according to the HKMA person in charge, the current agricultural non-point source pollution of Dianchi Lake pollution accounts for 40 percent, and 15 lake township agricultural population of about 700,000 people, an annual output of 100,000 tons solid waste per day about 280 tons. Collected as a result of the lack of lake township removal treatment systems, the main river into the lake and piles of refuse, garbage dumping in rural areas has become the main channel, garbage and sewage directly or indirectly discharged into Dianchi Lake.

To strengthen the management of garbage lake, early this month, the Government of Kunming Dianchi Lake basin has seven districts and counties, as well as municipal government departments to sign “comprehensive management of the target Dianchi responsibility”, 7 District Government and the township (street offices) signed responsibility and the responsibility to establish the risk of mortgage system objectives pc764 battery. 19, Chenggong County, first of all towns and districts have made the preparation of the 60 Board responsible to pay 120,000 gold Dianchi management responsibility to set an example, caused great shock in the county. Lake of the four districts and counties clear 15 township counties (districts) long and township (town) responsible for long as the first in 15 villages and towns to manage the establishment of Dianchi Lake, Lake area is responsible for the maintenance of cleaning the river, rural solid waste the work of removal and disposal of objects. Can not be completed on the responsibility of evaluation indicators, and will not be paid bonuses year-end appraisal, the risk of mortgage payment will also be turned over to the financial.

Followed by the district government, will be 15 in the lake township (street offices) to build agricultural solid waste disposal site 5, each village to build a refuse collection point 1-3 months to build about 700, with 32 removal trucks. These efforts will be completed this year, 1 / 3, complete next year.

Kunming landfill operation overload

Kunming Kunming sanitation and Environmental Protection Monitoring Center of the persons concerned that the current waste disposal area in Kunming City, particularly in the technology and cost, there are some insurmountable difficulties.

It is understood that the landfill, incineration power generation, high-temperature composting is now usually three kinds of waste, but all have their pros and cons of each approach. Landfill garbage is more of the principal means of its shortcomings is an area landfill, and the use of a short time (generally 10 years), high cost, especially in the treatment of landfill leachate has become a from all walks of life he could do nothing but pay close attention to the problem; and waste incineration power generation, it is characterized by a significant volume reduction through incineration to reduce the volume of garbage to make half or more, but the drawback is that the recoverable resources burned, releasing toxic gas, such as dioxins, mercury batteries, such as steam, and produce toxic and hazardous slag and dust; and high-temperature composting of organic need people to separate garbage and other refuse, and some analysts pointed out that it is actually relatively low efficiency, by sale and use of constraints inconvenience.

Monitoring Center, according to a sanitation engineer, the Kunming area currently two things landfill construction scale a total of more than 500, with a total investment of nearly 200 million, was designed daily capacity of 1500 tons, while the actual is overloaded, two each day, “eat,” 2300 tons solid waste, both in May 2001 into the use of the landfill site, originally expected useful life of 6 years to 3 years now time, has removed most of the space.

Dianchi who refuse disposal “bill”

For many years engaged in a senior engineer of environmental engineering calculations to press accounts, in theory, to deal with a ton of garbage to take up to 30 plurality, but far from fees and funding can not meet this requirement.

Landfill in the eastern suburbs as an example, 1300 tons of refuse daily, one-year deal with the cost of nearly 1,500 million, together with the financial allocations and charges may only reach over 200 million, making the landfill Kunming “stretched.” It is reported that the current waste disposal charges in Kunming still uses the old standard, government organizations and institutions to collect 60 per tonne, 20 Enterprise, residents 5 yuan per day, but the actual collection rate is very low, and the gap are in need of financial subsidies .

The Engineering pointed out that generally, to build a large landfill plant will take 1-2 billion, to build a large-scale take more than 20 million, and then told reporters he has a case in point: In May last year, hubbub of the units to be 3 to the joint venture was to invest 40 million U.S. dollars, to establish the first waste incineration power plant, but because of various reasons the project more than 1 year did not seem to have happened since 08k8192 battery. According to the senior engineers estimated that out of proportion to the input and the actual recovery may be one of the reasons why the project move forward.

Caohai Dianchi Lake Basin to watch women’s collections a year to 10 tons of garbage, the senior engineers are very worried about: “management of pollution in Dianchi Lake were his own, everyone must ask yourself what to do?”

Bottleneck in computer & notebook batteries

With the progress of the notebook computer technology, From a mobile office concept has already become a reality. In order to meet the needs of mobile and mainstream manufacturers are introducing more powerful, more stable system of ultra-thin notebooks. Used for this ultra-thin battery, but because of the lack of electricity has become a new bottleneck in mobile office. And, in addition to persistent power, the battery is very expensive prices, and a piece of notebook batteries accounted for 10% of the overall price -15%, then an ultra-thin laptop battery should have the characteristics of what it mobile office to meet the demand? From the practical point of view we may wish to analyze the design of laptop battery standard.

Industry experts believe that time is of the battery. Ultra-thin notebook computers because of the thin body makes room for the installation of the battery becomes more limited, and the battery means to reduce the volume of the power supply even shorter time, not every ultra-thin notebook computers can be up to standard the battery life. At present, a common ultra-thin notebook battery time between 2-3 hours, a good brand can be achieved for about four hours, there are higher, such as NECS820 will be able to provide electricity five hours time, and if equipped with backup battery, the life of up to 11.8 hours. Moreover, the computer which is designed to extend the battery very thin flat-shaped, and its size and the fuselage in line with the expansion of the bottom of the chassis battery integrated with the fuselage, and fully maintained the smooth state of the fuselage.

However, even the best batteries, its power can not be unlimited, and the total time spent, and a charge can be completed in the shortest possible time that the battery may be the user’s mobile office to offer as much convenience and efficiency. Which most users are often easy to forget where the most ordinary laptop charging time is 3-7 hours, with better products to be completed in 2.4 hours recharge.

In addition, some regular users to minimize the use of a variety of components to achieve extended battery life of purpose, for example, do not use CD-ROM, hard disk read as little as possible to reduce the screen brightness or simply dormant and so on. These approaches can indeed maintain the battery a little more time, but “a temporary solution”, select the design of a battery with excellent products, in order to fully enjoy the convenience of mobile office with the fun.

A new generation of lithium-ion battery Lithium & Nickel Synthesis

Recently, an important compound with independent intellectual property rights of synthesis of metal oxide materials have been in Beijing successfully applied to industrial production process, a new generation of key-ion rechargeable is Lithium nickel plate material officially put into production. The leading-edge technology at home and abroad is 4 years ago returning from overseas, led by its researchers Dr. Lu Following the rationale and manganese cobalt acid lithium then made an important achievement. At present, the production line of lithium nickel production capacity of 500 tons / year.

It is understood that the synthesis of lithium nickel production is internationally recognized as problems, only laboratory samples at home and abroad, there is no industrial production and application, which the establishment of production lines fills Lithium nickel international large-scale production of the blank, so that Lithium nickel practical applications become a reality. Nickel is a multi-valence metal elements, affecting the synthesis of lithium nickel factors is very complicated. Synthesis conditions of the process of change , it is easy to generate a slight impurities, reducing the storage capacity of materials. In the charge-discharge cycle, because of the existence of impurities in materials often lead to the collapse of crystal structure, and there will be serious impact on the electrochemical cycle life and safety. CITIC solid profits UNITA new Materials Technology Research Institute and Beijing University New Energy Materials and Technology Laboratory through 3 years of research, in a large number of laboratory work based on the synthesis of a unique and integrated a number of key technologies, developed the rationale for the production of acid in the nickel key equipment to realize the size of lithium nickel production industry.

Li-ion secondary battery as a high-power, short in the past 10 years, to replace the traditional nickel-cadmium and nickel-metal hydride secondary battery, has become the mobile phones, notebook computers, camcorders, DVD, CD and MD small mobile electronic products such as the main application of power, to promote the development of electronic and communication industry has played an important role. But so far in ion battery cathode material is mainly used in lithium cobalt. Lithium cobalt has a higher capacity and longer service life, although the comparison has been widely used, but the Cobalt is a strategic resource, a large scale in China have not found the value of cobalt mining, drilling of resources into the basic dependence Japan, which is very expensive, and nickel acid lithium in the process of charging and discharging poor thermal stability limit in a wide range of lithium-ion batteries in the field of application.

With the electric motor to power batteries and power storage batteries represented by large-ion rechargeable battery Kam rapid development of the plate material resources are being and safety of a higher demand, the traditional cathode materials for lithium nickel is obviously difficult to meet the lithium-ion battery development, it is necessary to seek a new generation of high-energy plasma to sleep cathode material. Preparation of soil by Bo and his staff will research into the current of the Ni-acid, lithium has an excellent electrochemical performance, capacity than lead-acid high health material more than 20%. The experimental results show that, as the treatment of chemical elements have been doped lithium nickel crystal structure in the stability of charge-discharge state, so that the material produced by the lithium battery recycling is not only superior performance, security, good performance, but also has a good filling ratio discharge performance. In addition, the synthetic material as a result of spherical particles, narrow particle size distribution, tap density, specific surface area of small, suitable for the production of various types of hammer-ion rechargeable battery.

The face of the earth’s resources has proven reserves of nickel is more than ten times the number of diamond and silver elements on the toxicity of the natural environment is also far less than the cobalt element, therefore, whether it is from the abundance of resources, goods, lead-acid or keys, to address the future resources, energy and environmental issues of great significance. China has rich resources of nickel, in this based on the development of a new generation of silver-ion batteries are Lithium nickel plate material is particularly relevant. Lithium nickel production line set up for full use of China’s nickel resources, China’s lithium-ion battery cathode material moving away from total reliance on imported raw materials situation, so that we can accelerate the development of their own intellectual property rights, high-performance lithium-ion toshiba satellite m100 battery lithium-ion battery to broaden the range of applications, led China’s energy-related industrial development will have a significant and far-reaching impact.

Doctor Lu by researchers and the development of lithium nickel establishment of production lines, indicating that China’s lithium-ion battery cathode materials have been in the international leading level, China has entered the field of energy materials in the ranks of developed countries.

Chlorophyll battery

Recently, there have been news reports that American scientists in the extraction of spinach chlorophyll-protein, the use of their characteristics of light energy conversion, solar cells made of the chlorophyll. Scientists said that after further improvement, this battery promising clean production, energy supply for the Pocket PC.

This chlorophyll is a kind of battery life based on solar cells, and its working principle is the conversion of light energy into electrical energy. This new invention will make use of their high performance and low-cost access to commercial production for the Pocket PC to provide a clean and green energy.

Scientists from a variety of spinach photosynthesis in isolated proteins, and Add them between two layers of conductive material. When there is light reach the micro-devices, the current rise. These proteins from spinach leaves in light to help plants into chlorophyll.

However, extraction of these proteins is not an easy task. These protein molecules are very fragile, and when they are removed from the natural environment, the work often can not continue. So the scientists put them in a mixture called peptide surfactant molecules. Such protection molecules in these proteins have the energy to form a protective membrane around so that they feel the same as in plants.

Protein was placed in a book on thin sheet metal, attached to a layer of conductive metal, the top of the organic material is conductive. When the light irradiation in the “fake sandwich” when will the release of proteins electronics, spread a layer of the metal layer under the current form.

Of course, the toshiba satellite m110 battery also needs to be improved. Now, they only have 21 days to sustain the current, and then on the end-of-life, so must try to extend the current time they have; now they are absorbed into the energy conversion efficiency of only 12%. Scientists hope that this proportion could rise to 20%, then the efficiency of its market than the silicon solar cell is even higher.

New battery electric vehicles premature

The appearance of a new electric bicycle, the key parts - the quality of the laptop battery itself, there may be “fatal” flaws. Yesterday, a few years the electric car technology research and sales experience into a red-hi engineers, revealed to reporters as well as many supermarket stores to sell electric car electric car batteries it is not configured in accordance with the principle of battery maintenance, resulting in a large number of new significantly reduce battery life.

Bought a lot of electric vehicles, will have such a feeling, bought the car not long, but somehow can not help feeling that power is insufficient, in the maintenance of points, after-sales service staff will be informed, “to replace the battery dying.” According to the Consumer Association’s complaints Nanjing analysis showed that, with the electric vehicle market continues to develop, followed by complaints on the quality of electric cars are the rapid growth of cases, among which, 8 as is for the poor quality of electric vehicle reflected.

Electric bicycle battery bad Why is it that easy? Hi in red under the guidance of engineers, journalists at the East came to a point-of-sale electric bicycle, a good plan in accordance with the prior discussion, the reporter disguised as a fancy electric vehicles, require sales staff will unload the car battery, the journalists face a special request, the sales staff seemed a bit reluctant. Into work quietly told reporters that the first note of the date of the battery production, the reporter saw a battery box mounted on the three batteries, the date of its production was not the same, which is 2 August 16, 2004 production , and the other one is September 6 production. Hi red to the sales staff was asked from time to time they have to charge the battery, in the face of the problem appears to face each other at a loss.

“The battery electric vehicles to hide the fact on here, and some sellers are not professional knowledge, it should be can not shirk its responsibility”! Cheng Hung Hei told reporters that the main battery electric vehicles is the stereotype, and by in-house, composed of sulfuric acid solution, if a certain period of time not to charge the battery, then the solution will precipitate sulfate, then have a resistance, would result in battery power directly decline. Specific performance will not be long for the charging, the battery will be hot, when cycling mileage will be manifested as inadequate. Into workers explained that the dealers in terms of electric vehicles for their own electric cars should be sold at least once a month and a half in charge, or will directly affect the life of electric vehicle batteries, in accordance with an electric car can be recharged more than 200 calculation , if we do not charge for more than two months, the battery life may be reduced by half. Buy a car but in reality, very few people have asked open the battery cover to see inside the battery manufacture date. Work into the public is advised to buy electric car, we must require sales staff will be equipped with a battery to open the lid, carefully check the date of built-in battery production, and most secure way is to choose the date of the battery factory one and a half months in the .

Japan's all-ceramic fuel cell development

Power companies by the various large-scale joint operation of the Central Power Research Institute in Japan has been committed to developing the full use of the heat-resistant ceramic fuel cells, at present, this work has yet known. The researchers do not use metal parts, but only the use of ceramic parts to connect power, which succeeded in raising the heat resistance. In the power generation efficiency is very high temperature of 1000 degrees Celsius to work, each square centimeter of electrolyte to achieve the output power of 1 W, which is equivalent to the traditional fuel cell 5 times. Expected that this technology will be applied to the family and the fuel cell vehicle. Institute for the mobilization of the battery manufacturers and machinery manufacturers to carry out joint research. Ceramics made by the fuel cell is the first in the world, the Institute hopes to realize 5 years later that the practical use of fuel cells.

Development there is the prospect of a solution is called "solid oxide-type" of the fuel cell. Fuel cell power generation in general is in part as a "cell" to get the reaction of oxygen with hydrogen to generate electricity. Electrode and electrolyte membrane placed overlap, and then connect the use of metal materials to connect a number of cell, and then collect the power cell, thereby enhancing the overall output power. Connect with the use of materials has always been easy processing and easy to pass current nickel plate. However, as the metal will be oxidized at a high temperature and aging, and therefore the need for power generation electrolyzer degrees in temperature control, so that the expense of output power. On the other hand, even if the connection between the ceramic, as a result of a chemical reaction caused by aging, people have worried that the hydrogen as fuel may leak.

Central Research Institute of Electric Power in order to inhibit chemical changes, add a calcium inorganic oxides, dissolves in aqueous solution into a sludge, and then in the electrode surface to form a thickness of 10 micron uniform ceramic membrane, thereby generating parts connected together.

If at the same time the use of ceramics and metals, such as different types of materials, as a result of heat expansion rate at different, that there are cracks, and the new technology to solve the long-term issue. Durability is also improved in the 1000 degrees C operating temperature under continuous operation time of 2,000 hours(372772-001), equivalent to the original fuel cell 50 times. Now, the endurance test is still in progress, in order to achieve practical, the researchers hope to work longer hours to 10,000 hours.

Battery lease

One of the elderly over sixty, in order to reduce cell damage to the environment, take the lead in Weifang made the concept of leasing the battery(75uyf), and started to invest in the creation of their own the cause of the battery lease.

The old man named Zhao new fields, is in Weifang, a retired Bureau cadres, 63-year-old this year. His early e-learning technology, in 1964 and graduated from Shandong University, in the subsequent decades, has been engaged in electronic-related industries, the use of batteries and their characteristics very well. The end of last year, Zhao field that a new lease on the battery information, the decision to do something for the environmental protection of its power, and therefore carried out in the city to explore leasing the battery.

After the idea, in March this year, Tian Zhao pension from their own money out of more than 4000 yuan, pre-purchased a part of battery charging equipment and rechargeable batteries, and began to try to engage in leasing the battery industry. Tian Zhao told reporters that he had been contacted and Weifang College, and the first pilot in the hospital, if the trials are successful, their business will further expand the battery lease.

He also told reporters that big a button battery to 600,000 liters of water pollution, and a rechargeable battery after ordinary "use - charge - to use" can be repeatedly used 500 times, both to save energy and protect the environment, and their consultation with the manufacturers, the last can not be used in rechargeable batteries returned to manufacturers, so that once the battery leasing business in the whole society will greatly improve the daily cell damage to the environment.

Recycling of waste batteries in Guangzhou for more than 4 tons of mobile phone battery recycling into focus

Sanitation sector from Guangzhou recently learned that since August last year in Guangzhou hotel hotel and the city's primary and secondary battery recycling bins layout, the current recovery than 4100 kilograms of batteries. Sanitation sector is stepping up its co-ordination work for the early population concentration in the commercial downtown, camera rinse stores, shopping malls and other places of electrical appliances are likely to place special barrels, current residents will be able to find the nearest hotel or schools run scrap battery collection point.

It is understood that in accordance with the provisions of State Economic and Trade Commission in 2001 to stop production and sales of our high-mercury batteries, mercury in 2006 to stop the production of batteries, battery, Guangzhou, the largest manufacturer of mercury-containing batteries currently in production in both countries to achieve the required standards. Guangzhou City, the vast majority of the battery is low mercury or mercury-free batteries, mercury batteries has been high production and marketing is strictly prohibited. Guangzhou does not encourage countries to focus the collection has reached a low mercury or mercury-free requirements of a waste batteries, cell phone battery recycling has become a new focus. According to environmental experts estimated that the waste out of Guangzhou, close to mobile phone batteries for more than 18 million in the recovery situation is highly unsatisfactory. Experts call for: the public must not be used mobile phone batteries(6y270) discarded at random, find the nearest hotel to the collection point or running schools.

Hot Electric Bicycle

Trackback: http://www.discount-laptop-batteries.co.uk/

Electric bicycle sales, battery recycling issue is the development of the bottleneck

Referred to as “small donkey” fuel scooters because the urban environment pollution will be banned tomorrow the road in the urban area. The industry predicted that the electric scooters will become the new darling of the public.

Fuel will be the history of scooters

The rise of fuel scooters in 1995, relying on a separate lubrication system, single-cylinder two-stroke engine, belonging to the non-motor vehicles, but in fact the speed to fast track non-motorized bicycles and pedestrians pose a security threat. Other fuel combustion scooters inadequate exhaust emissions in high concentrations of carbon monoxide and hydrocarbons, have done great harm to people’s health.

In response, the city government in 1997 made a fuel stop on the licensing decision scooters. In the past two years, as awareness of environmental protection among the people, the elimination of fuel rising voices of scooters, the city people’s congress deputies and CPPCC members the city several times to move the proposal. Last year, the provincial Economic and Trade Commission, Public Security jointly issued a document, etc., clearly stipulates that “fuel the use of scooters for the 5-year period shall not be delayed.” Accordingly, not long ago, the city government decided to December 25, 2003 to more than five years since the duration of the license the use of fuel scooters to implement end-of-life, since January 1, 2004, the highway in the urban areas - Century Boulevard - Chang Hung tunnel - Ring Road - Airport Road to form the closed loop (including the road) within the scope of, the prohibition of road traffic fuel scooters. It is reported that the city fuel scooters are involved in 58,000, of which there are 17,000 urban areas.

Electric bicycle and on homeopathy

Electric vehicle is a power-driven bicycle. According to the city of Valley Electric Vehicle Association president Decai introduced in 2002, sales of electric bikes for the whole country 1.6 million in 2003 soared to 3,000,000. Will be implemented in 2004 the “National Road Safety Law,” to determine the electric bike’s status as a non-motor vehicles. It is understood that in 2003 total sales of electric bikes in our city of about 45,000, but almost the size of the cities of Ningbo, Suzhou City, sales reached 90,000.

Electric bicycle and bike compared to the relative labor-saving, comfortable; compared with the motorcycle, the relative energy efficiency, safety; scooters and fuel compared to a relatively environmentally friendly, cheap. Growth in sales year after year prove that the market has some preference for electric bikes.

Ningbo, a number of manufacturers and sellers to seize the favorable opportunities came one after another. Ningbo large-scale access to Carrefour, Hymall more than 40 supermarkets, in 2003 electric vehicle production and sales of 40,000, based on in 2004 to 100,000 red slash. Xinjiang Xiamen city electric bicycle every day leading up to 50, sales of nearly 100,000 yuan. It is estimated that in 2004 the sales of electric bicycles throughout the city will reach about 60,000.

Battery recycling issues to be resolved

Electric bicycle also has “weaknesses”, that is, it uses no batteries, such as recycling, use, environmental pollution can be. It is understood that, at present, the use of electric bicycle aluminum multi-acid batteries and lithium batteries, which in the production process and use of the old battery acid and lead, chromium and other heavy metals, hazardous to humans. At present, the electric car not to discard old batteries relatively common phenomenon, the lower the recovery rate.

Fortunately, there are enterprises begin to take action. Electric car battery production in our province large “super-wai” battery company executives said that next year the company’s electric vehicles will recycle old batteries, make a commitment to the consumer: in 2004 to carry out 10 games in the country “green action” special events, publicity electric vehicle battery recycling old ideas.
