December 2 – U.S. International Trade Commission, China preliminary ruling to the U.S. exports to the U.S. solar battery related industries causing substantial damage, the ruling means the U.S. Department of Commerce will continue to enter China U.S. solar anti-dumping and countervailing “double reverse” survey. 　　

U.S. International Trade Commission announced the date of the Committee 6 votes to none of it was concluded that Chinese exports to the U.S. solar industry, the United States related to causing substantial damage. Earlier statistics show that in 2010 Chinese exports to the U.S. solar battery over $ 1.5 billion worth, doubling GDP in 2009. 　
　
According to the U.S. trade remedy case processing procedures, the U.S. International Trade Commission to make sure of the preliminary ruling, the U.S. Department of Commerce will continue to expand the “double reverse” investigation until January 2012 and March respectively, the preliminary ruling whether the Chinese exports to the U.S. solar battery imposition of countervailing and anti dumping duties.
　　
In mid-October of this year, the United States seven solar manufacturers joint appeal, claiming that 75 Chinese companies receive government subsidies related to price below cost dumping in the United States, asked the U.S. Department of Commerce and International Trade Commission launched investigations on China exports to the U.S. solar batteries impose high punitive tariffs. 　
November 9, the U.S. Commerce Department announced that China’s exports to the U.S. solar batteries placed on file, expand clean energy products for China’s first “double reverse” survey, the survey of specific products for the Chinese exports to the U.S. crystalline silicon photovoltaic batteries, modules, layer plate, panels and building integrated materials.
　　
Filing news, the Chinese PV companies issued a joint statement that China exports to the U.S. market growth due to competitive advantage, rather than dumping or government subsidies, American companies proposed the “double reverse” complaints are against Chinese products exported to the U.S. distortion of the status quo, and stressed that there is an error if the ruling, the future does not rule out the U.S. International Trade Court of Appeal. 　　

Chinese Ministry of Commerce said the United States Department of the global initiative to promote clean energy to provoke trade friction, the factors that led to their competitiveness to blame China’s industrial development has stagnated product competition, not only to undermine Sino-US energy cooperation, it also undermines the U.S. industry’s own interests, and with the global response to climate change and energy security challenges runs counter to the trend.

When the electricity is greater than the power consumption, while the battery can be charged while the device power, less power consumption, then use the electricity stored in batteries to compensate for the effect of weather changes in generating capacity. Price of 719,040 yen. The company will recommend a combination of solar cells with a way to expand sales.

U.S. McCormick School of Engineering and Applied Science, a research group, recently said that they use carbon and silicon mixed layer to today’s lithium-ion battery booster, has developed a new lithium ion battery, this battery is the original capacity of electricity 10 times, and the charge time is only the original 1 / 10.

The technology uses smart phones and other modern high-tech equipment used by the standard lithium ion battery, but instead a new type of electrode. New battery storage of electricity is a standard lithium-ion batteries 10 times, and full of power needed for less time.

The research is published in the “Advanced Energy Materials” magazine, the first authors Ha Luo Dekun grid, said: “We found a new extended life rechargeable lithium-ion battery to 10 times the original method, even after a 1-year , its efficiency is still on the market than it is now the lithium-ion battery 5 times higher. “using graphene (graphene) is a major breakthrough. Graphene is the thickness of the carbon and silicon atomic layer, but the defects in the graphene ion movement in the battery faster. Therefore, the battery will store more energy, and a shorter charging time. Grid-kun said: “We almost did best of both worlds.” According to the research group speculated that this new technology will enter the market in the next three years. ”

Today students have never complained about which mobile phone and laptop batteries are not to force it? Clearly, the battery life has become a phone / tablet biggest performance bottleneck. The good news is that the latest technology will soon make their charge rate and battery life has increased more than 10 times.

This magical effect from Northwestern University, the researchers adjusted the charge material, the use of silicon. Traditional lithium-ion battery electrolyte in the activities by the electrons to charge, more effective alternative material is silicon, because each silicon atomic energy with four lithium atoms, while the ordinary graphite anode battery every six carbon atoms with only a lithium atoms.

Although silicon is a good alternative materials, but it is charging process is very easy to expand and contract, resulting in damage to the battery. To solve this problem, Northwestern University research team will graphene sheets and folders into a sandwich-like silicon, to avoid the fragile battery problem (do not fly so ye listen to squeeze …..)

Researchers are still thin on the drilled holes 10 and 20 nm, to shorten the charging time. Next, the research team also talk about improving the battery cathode and electrolyte, the battery is disconnected automatically after a full, good to prevent the battery temperature is too high due to fire or explosion.

Speaking of ignoring the many more dangerous situations that may occur after the use of silicon super cell is still pretty to look forward to, Xiaobian hope that it soon out of the laboratory for the benefit of the masses.
