On the development status of China lithium battery industry

With China’s economic development, global Li-ion battery demand continue to ascending with applications expansion every year. China is second only to Japan in the lithium-producing countries, market growth is huge. At present, China lithium battery industry has been gradually expansion to electric bicycles, electric cars and other areas. LP154WU1 (TL)(A2) LP154WP1 (TL)(D1)

The development status of lithium-ion battery in China

Lithium-ion battery production in China is still in the initial period, there is no large-scale enterprises to enter a production phase. However, the state encourages the development of lithium-ion battery production, battery factories and some strength enterprise groups in China have seen the potential market for lithium-ion batteries, they are preparing or have invested heavily in production of Li-ion batteries, these practices will undoubtedly promote national lithium-ion battery industry.

China Li-ion battery production mainly in the north and south, each with several companies to prepare for large-scale investment.

However, though China has large demand and production of lithium battery, technology is relatively backward. LP154WP2 (TL)(C2) LP156WH1 (TL)(C1)

1. Separator and electrolyte heavily dependent on imports

Now the key materials such as lithium and the electrolyte membrane are imported from abroad, only divide the costs to account for 20% -30%, if the future success of domestic R & D localization of the membrane and electrolyte, the price will be further significant decline. CAS Guangzhou Chemistry Co., Ltd. assumes a major science and technology projects in Guangdong Province, Guangzhou City, focused on science and technology projects, “Li-ion battery separator material”, the current breakthrough. Has established an annual output of 15 million square meters of the lithium-ion battery separator pilot production lines, solved the structure of homogeneous preparation of precursor films and technical problems, mastered the preparation of microporous membranes continuous stretching process and technology, in particular, to master Control of membrane structure technology and techniques, the corresponding patent application. It will reduce the price of lithium-ion batteries to contribute. LP156WH2 (TL)(A1)

2. Production process varies

Since the lithium battery manufacturing technology and equipment there is a gap, the domestic lithium battery production technology mixed, manufacturing standards has not yet reached agreement. Lithium batteries used in electric vehicles are connected in series or in parallel, if the consistency issues are not well, then the large-scale production of lithium batteries used in electric vehicles will not be able. 338794-001 361742-001 371785-001

3. Lack of intellectual property

Currently in the study of lithium iron phosphate has made a breakthrough, but the U.S. patent in this area, so although some of our links to independent research and development, but in intellectual property issues, but also do not know how to respond.

4. Very few international certification of raw materials

Now the production of raw materials used in lithium batteries can not all imported, mainly from Taiwan, but China through international certification of raw materials to produce lithium-ion batteries in order to be internationally recognized, so the link in the certification of raw materials and also some problems. 372772-001 398876-001 417066-001

Japanese University professor predicts the cost of battery will halving in 2015

The automakers have focused their attention in the world of electric vehicles today, the new rise of China plans to reach 5 million by 2020 and 15 million electric vehicle hybrid electric vehicle ownership. Colleagues around the world is obsessed by the problem of vehicle - cost, power, load and other issues will be how to respond? Global Automotive Forum, held recently, the Japanese professor at the University of Fukui, predicted that by 2015 the cost of the battery will decrease by half.

In the next 10 years to reach the target of 20 million new energy vehicles, and now look seems very urgent. Car prices ordinary new energy vehicles until at least next year on the market. Xiao, vice-president of Shanghai Automotive Industry Group, the country & P said that in 2012, the Roewe 550 plug-in hybrid models will be listed higher. Deputy President of Chang’an Automobile, the market, said the year Minister Wang Jun, Benben pure electric vehicles next hybrid vehicle sales this year as Chang 1000. Toyota is studying pure electric vehicles in China, the possibility of market penetration in 2012 to have “Zhunxin children.”

Not only that, now able to benefit from the purchase of hybrid electric vehicles and subsidies for only five pilot cities, the future will continue to increase despite the pilot, but the popularity of time at the national level remains to be seen .

In addition to the shift in models, car prices, national and international training for power development of new vehicles is the cost of a high degree of consistency. director of Honda, head of planning of environmental security, told reporters the bamboo basket Michio the original: the cost of electric vehicles is the world’s problems. Toyota President Katsuaki Watanabe said the deputy, as manufacturing costs are high, Toyota will create a simple structure, low cost technology and mass production of these models to reduce costs. But Toyota has a high sales volume for the support: Currently, Japan has sold 60 million units of hybrid vehicles, vehicle sales in Japan this year, hybrids will represent 16% pure electric vehicles will account for 9%.

domestic production of electric vehicles in China is difficult to form a scale in the near future. Currently, only the development of low-cost technology to reduce production costs. It is understood that the cost of the farm household energy is 1000 U.S. dollars per kWh to 20 kWh of energy calculation of electric vehicles, only the cost of the battery to reach 2 million.

Fukui University of Japan, the former Chrysler - Mitsubishi Motors R & D Steering Committee Co-Chair Andong Hong light is to reduce the cost of the battery holder confidence. He said: According to the analysis of research, if the costs of the battery in 2010 as the base in 2015 will decrease by 1 / 3, 2020 fall in this 1 / 5, 2030 increase to the current 1 / 10. Fukui University, according to projections, by 2015, the cost of the battery will decrease by half.

In Japan, government subsidies for electric vehicles at ¥ 100,000 each, but sales of hybrid cars are still much better than pure electric vehicles. bamboo basket Michio initial analysis, this is due to hybrid cars have better dynamic performance. It is understood that the driving force of energy the battery can only play a gasoline engine of 5%, well below potential should play. Compaq presario CQ70 battery Compaq presario R4000 battery

The new solar energy conversion method can double solar cells efficiency

Stanford University engineers announced that the joint use of both solar radiation can heat and light way to generate electricity, provide more than twice the existing technology more efficient solar cells. They found and proved the effectiveness of this aspect, this method is called “photon radiation enhanced hot-ion” (referred PETE), will be able to reduce the cost of solar energy products, low enough to compete with the energy and oil.

Most solar panels use semiconductor materials silicon converts light into electricity. However, these cells use the sun only part of the spectrum, the other only had a fever. Do not use the sun and the battery itself, the heat generated by the low efficiency, resulting in the arrival of more than half the energy from solar to battery power is lost.

If the residual heat can be used to collect a certain way, the efficiency of solar cells much more than now. The problem is thermal conversion system of energy requires a higher temperature, while the efficiency of solar cells decreases rapidly at high temperatures.

The team leader Meloshe is covered with a thin layer of cesium metal in a semiconductor material, which can make the material while enjoying the light and heat energy to generate electricity. Dell Inspiron 1320n battery Dell Inspiron 1410 battery

“We describe a new physical process, not a mechanism-based photovoltaic standards. But as you can imagine is a very high temperature can be performed under the photovoltaic response.” Meloshe said. “Actually, it works better at high temperatures, as high as possible.”

The cost of materials is the development of solar energy industry as a constraint, a reduction of capital investment in solar construction is a big advantage.

“PETE approach to the rapid development of solar energy a real possibility.” Meloshe said. “Even if we can not achieve perfect efficiency of the use, for example, we improved our performance solar energy conversion of 10% efficiency power conversion from 20% to 30%, while (and compared to existing systems) to improve production capacity, a total of 50%. ” toshiba pa3191u-1brs toshiba pa3191u-2brs

And this increase is enough to make solar energy and oil to competition.
