Major projects for electric vehicles
Organize by the Tianjin Science and Technology Commission, Tianjin Qingyuan Electric Vehicle Co., Ltd. and Tianjin FAW Xiali Co., Ltd. to take the lead, Tianjin Hi-Tech Power Blue Sky Co., Ltd. and China Automotive Technology and Research Center compaq laptop battery, evo n400c battery, Tianjin University some ten units, such as shared responsibility the National 863 Program - a major special Pure electric vehicles electric car project, in the June 25 adoption of the National Ministry of Science and Technology Acceptance. Experts believe that the skill level of the car reached the international advanced level.
Xiali pure electric cars using the city's R & D China Automotive Technology and Research Center, Tianjin Hi-Tech Power Blue Sky Co., Ltd. and Tianjin University of Technology category of complete scientific research system, the application of Tianjin Hi-Tech Power Blue Sky Co., Ltd. developed lithium-ion evo n410c battery, evo n600c battery power sophisticated technology, the integration of technology and industry dual advantage, in the country has developed the first batch of five has the international advanced level of pure electric cars, and will realize the industrialization of two years for the city and even the formation of our country electric vehicle technology, self-development capacity , automotive technology and realize the rapid development of industry have laid a foundation.
Practical use of lithium-ion batteries available for more than 10 years, the technology is developing rapidly, as an advanced power supply types are widely used in mobile phones, laptop, camera, space, communications equipment and other fields. With energy shortages and to strengthen environmental protection awareness, improve, since 1995 power-based lithium-ion battery research has become a hot issue around the world, major evo n610c battery, evo n620c battery, presario 1200 battery manufacturers is that end has invested substantial human, material and financial resources.
At present, Tianjin Hi-Tech Power Company Limited to use the blue sky at lithium-ion battery research, development, technical superiority and talent advantages, have research and development of the D-, F-type, 20Ah, 35Ah, 55Ah, etc., high-capacity lithium-ion power batteries, and made some achievements. Especially in the "Ninth Five-Year Plan", "15" during the country assumed the Ministry of Science and Technology issued a number of major scientific and technological power battery projects, independent research and development of 8Ah, 55Ah, 90Ah Li-ion battery power, small combination charger, smart presario 1800 battery, 116314-001 battery, presario 700 battery management systems.
In 2008 Beijing Olympic Games under the leadership of the green, with the lithium-ion power battery technology continues to improve lithium-ion power supply will become the field of the future power of new technologies and economic growth.
French Axane will be listed two kilowatts
According to overseas media reports, French Axane Fuell CellSystems held recently at the "First European Hydrogen Energy Conference (EHEC)" announced in 2004 will be listed on removable fuel cell.
Upcoming are the solid polymer type fuel cell, merchandise called "Roller Pac". Output power of 2 kW, Overall dimensions of 98cm × 54cm × 64cm, weight 75 kg, mainly for back-up power and uninterruptible power supply. Prices, one-kilowatt compaq laptop battery, fru 92p1121 battery book for 8-1000 euros. At present, this fuel cell is still in its trial stage, "production will further reduce the volume and weight."
Such cells, hydrogen as a fuel to accommodate the ball-type containers, when the hydrogen can be run out to replace the container.
Axane companies are operating the French industrial gases group Air Liquide (AIR LIQUIDE), established in 2001, fuel cell development company business notebook nc6000 battery, business notebook nc8000 battery.
Casio prediction 10 years after the portable
With the "WPC EXPO 2003" workshop held at the same time, "the fuel cell is about to infiltrate into portable devices" (September 17, by day by day by the electronics and environmental protection held in common), the Casio Computer stand equipment manufacturers stand up to 10 years after the portable device power supply is predicted. Then such power will be divided into at improvement on the traditional model of technology and fuel cell technology. Personal computer in the fuel cell will replace the existing rechargeable battery power supply into the mainstream. In digital cameras and handheld computers in areas such as fuel cells, lithium manganese batteries 1st grade as well as next-generation lithium-ion batteries will coexist. At Walkman (Walkman) and the field of low-power radios, etc., apart from the company's prediction of fuel cell, alkaline manganese batteries, as well as one at the electric double layer capacitors (EDLC), such as rechargeable thinkpad x30 battery, thinkpad x23 battery, the solar cells will arise and the use of human body temperature and exercise the power of natural energy.
Required, such as laptop at 1000Wh / L or more for high energy density of energy, fuel cells because of the way of direct methanol (DMFC) output power density not enough, it will be used by changing the methanol supply of hydrogen fuel cell modification. DMFC current output power density of 50mW/cm2. "If not 100mW/cm2DMFC will not be able to use" (the company's technology All in all elements of the Department of Shionoya Masaharu). At present, the maximum data 50mW/cm2, at present the use of platinum catalyst and acid (Sulfonic Acid)-type polymer electrolyte membrane material systems has reached its limit. As long as the failure to develop a new material of the technology will be difficult to achieve. On the other hand, modification type are developed by Casio, and because of the use of pure hydrogen, will accordingly be able to improve the output power density and reduce the volume. However, "also thinkpad t61p battery, thinkpad t60p battery at a similar stage of arts and crafts" (Salt Valley). The key lies in how to achieve volume production in order to reduce costs.
In digital cameras and handheld computers required 800 ~ 500Wh / L over the field of intermediate energy density will be used to quality-type fuel cell or DMFC, but the next generation of lithium-ion batteries will continue to become the mainstream.
At Walkman, radios and electronic dictionaries, etc. Just 300Wh / L energy density of the following areas at DMFC fuel cells will become a mainstream product. The company has been in the study can replace the batteries on the 5th of the DMFC. In his speech, the company displayed at the upper cylindrical module is equipped with electricity, with lower methanol used to store the type and at the Department of thinkpad t40P battery, thinkpad a22 battery power module is equipped with fuel cells on the 5th of the illustrations. Shiotani stressed that the batteries can be recycled by the shell material or biodegradable plastics (Biodegradable Plastics) composition, because of recoverable re-use will be easily acceptable to the community.
