Recently, auto industry consultant for the research department was informed that starting this year, Germany launched a 360 million euros vehicle lithium-ion battery development program, almost all German cars and carry-owned energy giant to join.
The German government said the plan, the German mark will enter the era of electric vehicles. At the same time, Daimler Motor Company and RWE energy company that will work together to build 500 electric vehicle charging station. German auto industry alliance is expected to Germany in 2012 will be completed before the series of electric vehicles and off commercial production started.
According to the consultant for the automotive industry analysts pointed out Lee Sheng-mao, new energy sources for electric vehicles is the focus of automotive development, and the driving force for lithium batteries for electric vehicles is a source of motivation, the present power lithium battery technology bottleneck is almost resolved, the upcoming production stage to enter the industry. Now, the international automobile giants have been developed and will be the development of lithium battery power on the strategic position.
At present, Japan’s R & D aspects of lithium batteries in the world. Disclosure by the Industrial Policy Bureau of Japan, Japan will strive in 2010 the new lithium batteries for next-generation electric vehicles. Toyota, Nissan Motor and Matsushita Electric Industrial Co. Ltd. signed an agreement and other related enterprises, efforts to develop uniform specifications for a new generation of automotive lithium-ion battery, and plans volume production in 2 years. Toshiba decided to spend ¥ 50,000,000,000 Development of electric vehicles using lithium-ion battery, this high-performance driving force within the next two years to enter the semi-commercial production.
Popularization of electric vehicles is a critical need to have sufficient power to add bases. Tokyo Electric Power announced that it would take the lead to participate in the infrastructure construction in the metropolitan area to more than 200 charging stations, after three years to more than 1000.
Tokyo Electric Power has successfully developed large-scale rapid charger, the charging time significantly shortened. It is reported that a full charge every 10 minutes, beyond the distance they traveled is 60 km. At present, the cost of the establishment of a charger is ¥ 4,000,000. The company in Japan’s supermarket car parks, convenience stores and post offices and other public places have building equipment chargers. It is estimated that if the high-performance lithium batteries for more promotion, in Japan the use of the hybrid to reach the level of 7.2 million. Industry believes that the electric car market to the development of the next decade to how the size will depend on whether the cost of lithium batteries can quickly be reduced.
Driving force in the development of lithium batteries and electric vehicles, the distance between China and developed countries have been getting smaller and smaller. According to “Nikkei Electronics News,” the statistics, at present, in BYD Li-ion batteries and nickel-metal hydride batteries only in Sanyo, Sony and Panasonic, the become with each of the three Japanese manufacturers of the famous giant international battery. In the field of electric vehicles, BYD can say that has to go the forefront of the industry. BYD market by the end of 2008 hybrid vehicles F3DM, can be the same as mobile phone, the charging socket in the home, that is over seven hours, broke the electric vehicle battery charging station to be in professional charge of the bottleneck. Hybrid vehicles in general use in low-speed electric drives, high-speed motor on the need to drive with the engine and fuel. However, F3DM electric drive can be used alone, the maximum speed of 150 km and range up to 100 km mileage. In contrast, the currently available dual-mode technology — the other two companies General Motors and Toyota are the electric cars for sale, a charge can only travel 25 kilometers.

Researchers at University of Waterloo, Canada May 18 said they made more than a traditional large capacity lithium battery 3 times the lithium-sulfur battery prototype. The date of the relevant research published in the “natural materials” online magazine.
Lithium-sulfur batteries have a very broad application prospects, chemists have therefore conducted the study over the past 20 years. Sulfur and lithium is considered the most ideal material for a battery, these two chemicals in combination can not only provide high energy density, stability, security and better life also. In addition, the cost, the price of sulfur is also far lower than current lithium batteries are widely used in the other materials.
However, the manufacture of cathode battery problems has been a major problem of people, partly responsible for the charge and discharge and release of electronic storage, in which reversible electrochemical reaction in order to achieve a higher current, which must be similar to the sulfur and carbon Such a conductor in close contact, and after a very effective way to no.
University of Waterloo professor lida.nazer research team led by technology through the nano-carbon and sulfur close integration. They used in the experiment is known as a porous carbon mesoporous carbon material. In the nano-level, this type of carbon in the pore size and pore volume is very consistent. Through nano-technology, the group will produce a hollow carbon tubes, each 6.5 nanometer thick, 3-4 nano-aperture. Sulfur may be due to heating and melting, when the exposure to carbon nanotubes after they are inhaled and solidification contraction for sulfur nanofibers. Through electron microscopy studies on the perfusion of the carbon nanotubes have sulfur profile inspection found that in all of the aperture in both full of sulfur, carbon and sulfur to achieve a perfect combination.
Nazarbayev said that by such a composite material made of battery power by up to 80% of the theoretical value, but also in maintaining a lower cost, good stability and a better circulation of the premise, its energy density than traditional lithium - transition metal oxide cathode of the battery into the high-3 times. This porous carbon materials “sucked up” technology to other composite material also provides a new way. Study in the future they will also further improve the structure of such a cathode material and performance.

Konarka recently the United States announced a new invention, can be installed in the glass or other transparent material on the solar panels, the invention can be applied to ordinary solar cell construction, including the glass walls and windows can be used on this solar cells.
The company’s transparent solar cells on glass in the general assembly, the user can have a variety of colors to choose from. Including red, blue and green. Such solar panels based on organic photovoltaic technology, but the conversion efficiency than ordinary silicon solar panels, the company’s current product energy conversion efficiency of 6%, while the ordinary silicon solar cell conversion efficiency board of up to 20% .

Japanese Economy, Trade and Industry recently decided to put solar cells will support economic growth in Japan’s position of technical fields, and actively promote its technical research and development, the expansion of Japanese products in the global share; amendment “in Japan to popularize and promote the use of solar energy Plan of Action “in order to enhance public facilities on the use of solar energy.
Japan Patent Office (JPO) Statistics 2000 to-2006 in Japan, the United States, Europe, China, South Korea in five countries and regions, the total solar cell patent applications from Japan amounted to 5,449 applications, accounting for 68.4%; which At present, the most popular applications for silicon solar cells reached 75% -81%, far ahead in Europe (8% -11%) and the United States (5% -7%). In other words, in response to global warming green energy - solar cell area, Japan is still the world’s largest number of patented technology. However, a more universal type of thin solar panels a new generation of materials technology - an organic semiconductor solar cells, originated from Japan, the United States and European patent applications were 45%, 29% and 19%, and European research institutions in the important journal published papers in the field of 126, is Japan (29) more than 4 times. JPO accordingly that the Japanese area of organic semiconductor technology research and development of solar cells has lagged behind Europe and the United States.
According to relevant information, Economy, Trade and Industry in March 2009 on the Japanese scale of the next solar industry forecast: the current environmental protection has been widely favored energy background, the Japanese production of solar cells will be rapid growth in product sales to the industry in 2020 will expand to 10 times lower than the current, amounting to 10 trillion yen (about 7,040 billion yuan), the staff size from the current 1.2 million to 11 million people.
Organic semiconductor solar cell production costs are lower, but in actual use for the goal to increase its power generation efficiency is still the need to study. JPO considers it imperative that cooperation between the Government and the people committed to high-efficiency solar cell materials development, the future of Japan in the field to continue leading.
