Mobile phone battery life, a cause for concern

A recent survey shows that 79% of the dissatisfied users of mobile phone laptop batteries. Of which 37% of respondents feel that mobile phone battery standby time is too short, day-to-day use to keep charging, and business travel is also very inconvenient; there are nearly 20% of people feel that mobile phone batteries in general, can not meet MMS, polyphonic , camera, Bluetooth, games and other multimedia needs.

It is reported that a large number of mobile phone screen to upgrade to more than 65,000 colors, camera functionality is toward the megapixels, coupled with high-quality ring tones, built-in games, video playback applications such as the rapid popularization of mobile phones more powerful, less power consumption to the greater. Equipped with double-double charge, carry a spare cell phone consumers in many ways to solve this problem. “Durable demand for the original standby limited to specific user groups, but gradually developed into a universal demand.” Konka vice president of marketing communications, said Han Xiaoming, demand changes in the birth of a huge market opportunity, Konka most energy-efficient technology in recent years accumulation of research have begun to get a return.

“Communications technology is the basis of standardization, and the demand is differentiated. The difference between the market demand analysis, based on the formation of the final product differentiation Konka competitive advantage.” Konka communications market, according to the Ministry of person in charge, Konka taken to market demand-oriented IPD Integrated Product Development System, this system has an emphasis on research and development needs in the market and competitive analysis based on the selling points of product differentiation.

It is, Konka began as early as last year with a well-known market research company in Hong Kong co-operation needs to carefully study the market. Through research, the target users Konka players are divided into super-type, technology type, such as practical four groups. HAN Xiao-ming said that in November the main ultra-long stand-up to play the main standby battery of the “protracted war”, and to achieve product sales objectives heavyweight.

China’s promotion of low-mercury-manganese dioxide batteries to reduce the use of Ni-Cd battery

China will gradually increase the amount of less than 0.0001% of mercury in alkaline manganese dioxide batteries in the battery in the proportion of one-time, to encourage the development of lithium-ion batteries and nickel-hydrogen rechargeable batteries, such as alternatives to rechargeable nickel-cadmium batteries, nickel cadmium batteries to reduce the production and use, the final out in the civilian market Ni-Cd battery.

And so on in accordance with the State Environmental Protection Administration jointly issued 5 batteries pollution control technology policy, as well as the mercury content in batteries than 0.0 battery quality and 25% of the manganese alkaline manganese batteries, in accordance with the relevant provisions of the country have been banning the production and sales. 1 January, 2005 will halt the production of mercury is greater than 0.0001% of the alkaline manganese batteries, will also gradually reduce the production of battery paste and sales, and ultimately out of battery paste.

It is understood that the high-capacity alkaline batteries battery capacity than the low-65 percent reduction of environmental pollution, low-capacity rechargeable battery than the battery one-time 99 percent reduction in pollution of the environment. Therefore, this policy to encourage and support consumers to use less than 0.0001% mercury content in the high-energy alkaline zinc manganese dioxide batteries, nickel hydrogen batteries and lithium-ion rechargeable batteries to replace nickel-cadmium pa3399u-2brs battery to encourage and support consumers refused to purchase, use substandard and counterfeit products, as well as the battery is not correctly marked on the battery logo products.

NEC introduced the classic ultra-thin notebook computer batteries

A few days ago, NEC launched the classic ultra-thin notebook battery— NECS820, new product with a backup battery, you can without any external power supply in the state of non-stop from 9:00 am to work until 20 o’clock, and be able to 2-4 hours for the battery is fully charged.

According to industry, currently on the market most ultra-thin notebook computers, cell expansion have not been able to achieve “full portable,” and after loading so that the lower part of the formation of protruding body not only affects the body beautiful also reduce the portability of users this is a fly in the ointment.

NEC’s S820 is designed to extend the battery very thin flat-shaped, and its size is fully consistent with the fuselage, with the expansion of the bottom of the chassis battery integrated with the fuselage, and maintain the integrity of the body beautiful and smooth state.

Hydrogenation few points into the development of fuel cell vehicles in Japan barriers

Recently, the Japanese experts estimate that by 2010, the fuel cell market size is about 1 trillion yen (110 yen about 1 U.S. dollars) by 2020 is expected to reach ¥ 8,000,000,000,000. However, the development of fuel cells are also encountered some difficulties. For example, the price is too expensive, too few hydrogen refueling station. Metropolitan area in Japan is currently only 10 hydrogen refueling station. Although the rate of a hydrogen can be driven 350 km, but because too few hydrogen refueling station, the battery in the left two-thirds of the hydrogen, they often have to start thinking about where the next hydrogenation.

Japan in May this year issued a formal “strategy to create new industries”, the development and application of fuel cells on the pivotal position. December 2002, Toyota and Honda to market fuel cell vehicle, the two car companies to the Japanese government to pay 55 fuel cell vehicles. Now, the two companies have already produced fuel cell vehicle 28.

Where the fuel cell vehicle by the person that spoke with one voice to praise the performance of vehicles. The noise is very small, a maximum of up to 145 kilometers per hour, a hydrogen fuel supplement may be traveling 350 kilometers, and refueling vehicles traveling a similar distance. According to experts estimate that by 2020, Japan’s fuel cell vehicle up to five million.

At the same time, fuel cells are entering the homes of ordinary people. In May this year, Tokyo Gas Company to demonstrate the use of residential fuel cell demonstration. In the display, located outside of the household fuel cell to provide domestic electricity toshiba satellite a105 battery thus saving the annual lighting and hot water costs from 30,000 to 50,000 yen.
