China's auto energy reform
China's auto energy reform
Chinese car brands have sprung up everywhere lithium-ion battery
Caused by the global financial crisis hit economic recession, coupled with growing global oil extraction, the severe energy shortage situation, on a global scale, a technology about cars energy reform battle is brewing.
Japanese automobile producing countries, depending on the development of lithium-ion cell vehicles in response to financial crisis, the strategic choice of lithium-ion battery on the car was applied to passenger cars, Toyota, Honda, Nissan, coincidentally in 2010, has an annual production plan; farther Europe and the U.S. also set off a lithium-ion battery in the car craze, GM also announced this year, will build a factory producing lithium-ion battery to provide to the Chevrolet Volt.
A new round of the lithium-ion battery electric vehicles as an alternative energy whirlwind is blowing, lithium-ion batteries becoming the new darling of car dealers in 2010, many people will open on the lithium-ion rechargeable battery car. Meanwhile, the domestic national brands automotive lithium-ion batteries are also sprung up everywhere.
BYD
BYD started to do the battery in the battery on the road vehicle research and development, overseas auto giants are not lost. BYD independent research and production of the world's first lithium-ion-driven hybrid car Hybrid-S, the motor drive system by lithium-ion battery energy storage and energy supply. BYD December 15 last year successfully launched the F3DM dual-mode electric vehicle, the car uses gasoline-electric dual system, electric system, can travel 100 km, the maximum speed of up to 160km / h. Meanwhile, the BYD E6 is a pure electric car, using the "iron battery" mainly composed of lithium iron phosphate, raw materials for iron salts, phosphate and lithium carbonate, lithium-ion batteries are the areas.
Geely Panda
Geely also has its own lithium-ion battery models. Geely launched last year in the Guangzhou Auto Show Geely Panda electric car LC-E, with 40Ah lithium-ion battery system voltage 340 V, fast charge only 1 hour, this is undoubtedly a walk in the country in the forefront of developing new energy vehicles.
Chery
As the largest independent brand car manufacturer, Chery Automobile Company plans to launch two before the end of 2010 based on its existing hybrid petrol-driven cars. Meanwhile, sources said, the Chery QQ compact car is based on its development for office workers to use a lithium-ion battery-powered electric cars, electric version of the QQ on a single charge driving range of up to 100 km. As for when the car market, Chery has not been disclosed.

StrategyAnalytics: III-V family of solar cells
StrategyAnalytics: III-V family of solar cells
StrategyAnalytics: III-V family of the rapid growth of solar cells by 2012 will account for 10% of the global PV market
Recent studies report predicts that the global PV market in 2008 will reach 20.2 billion in 2012 to grow to 35.2 billion U.S. dollars, the annual compound growth rate of 23%. Rapid growth from the global renewable energy market.
In the Dec. 9, at the "2009 Korea Green Energy Conference", Strategy Analytics Asif Anwar, GaAs Services director, said, "In 2008 the dominant crystalline silicon solar, share about 89%, but look to the future, its share will decline, mainly due to compound semiconductor thin film and intense competition. "" lower cost thin film solar cells, crystalline silicon does not consume, the traditional crystalline silicon solar manufacturers have started to pay attention thin film solar, such as Q-Cells and Sharp Corporation.
Mr. concluded: "III-V family of solar photovoltaic cells have a higher conversion efficiency and low amount of material advantages, so that by 2012 133% compound annual growth rate of the total market share of 10% .
MB that this year China will reach 6,000 tons of cobalt stocks
December 8 Xinhua news briefing according to British metal collection, this year China is about 6,000 tons of cobalt stock, equivalent to 1 times last year.
According to MB in the survey, said buyers of a cobalt salt, cobalt stocks this year, not including China, Jinchuan, but also still have 5000-6000 tons. Other people in the industry think that this year's stock should be 3000-4000 tons. And they estimated that the inventory in 2007 is 2,400 tons of cobalt.
According to a trader in Jiangsu Province, said to 11 the end of the Jinchuan holds the hands of 2,500 tons of cobalt inventory. There are already many people think that prices have hit bottom, and cobalt concentrate prices have dropped to 10 dollars or less.
Many in the industry claimed that the second half of weak demand, many manufacturers have cut production, some people even think that cobalt production has been shut down by half. He believes that many medium-sized companies have reduced production of 50-60%, while many small businesses have closed.

U.S. iSuppli: solar cells Silicon Materials
U.S. iSuppli: solar cells Silicon Materials
"In 2010, silicon solar cells supply and demand will ease. Prior to 2009, the spot market price will drop substantially." - United States, iSuppli senior analyst in charge and the total (Senior Director and Principal Analyst) Henning Wicht seminar organized in the company "iSuppli Japan Seminar 2008" on crystalline silicon solar cells on the material - polysilicon supply and demand situation made such a prediction.
Wicht of the polysilicon material manufacturers in the production, and so calculate the future supply of polysilicon materials. The results show that the demand for polysilicon solar cell manufacturers announced crystalline silicon solar cell unit with an annual capacity of 0.8 times and so on.
Comparison of demand and supply we can see, the 2010 balance of demand and supply, then supply will greatly exceed demand. As supply and demand balance, 2010, after the polysilicon material prices will fall.
And, Wicht said that demand in 2009 increased by 34% over the previous year, while supply increased by 100% than the previous year, supply exceeds demand. Part of the solar cell manufacturers will be unable to order the polysilicon materials consumption, to the spot market for polysilicon materials increased. The results will lead to 2009 the spot price of polysilicon materials has dropped significantly.
Specific price: 2008 spot price for the 400 U.S. dollars / kg or so, 2009 will drop to $ 250 / kg or so. Since then, the spot price will also be a slow decline in 2011 will drop to $ 100 / kg or so.
"Nikkei Micro Devices," Introduction to Symposium forthcoming solar cells "from crystalline silicon to quantum, from basic understanding of solar cells."

Toshiba methanol fuel cell
Toshiba methanol fuel cell
Toshiba recently announced, will soon release its first methanol fuel cell that can recharge the battery more quickly, the first methanol fuel cell will be released before March next year.
Methanol fuel cell for which Toshiba did not reveal too many details of the parameters and life and so on, but just held the Japan Electronics Show Toshiba shows fuel cell phone is not difficult to imagine that Toshiba is the real thing this time. It was revealed that the methanol fuel cell is methanol, water and air to provide energy in the reaction, and produces only water vapor and carbon dioxide, very green. If you want to charge the battery, then just take a few seconds to add alcohol to it.
EU has proposed a new cell phone battery design new regulations
It is reported that the EU is considering the introduction of a mobile phone battery can be easily replaced on the official regulations, the regulations and the EU before the introduction of the RoHS (Restriction of Hazardous Substances) directive similar. New regulations require that the phone battery can be replaced easily, such as frequently used to remove the current mobile phone remove the battery cover replacement method.
However, Apple's iPhone and the iPod is far and this idea, the user must return their iPhone or iPod battery replacement company can be.
Although the details of the new regulations mobile phone battery is not clear, however, understand that the main thrust of the new regulations is to reduce the number of used batteries in the garbage. If Apple can prove to the EU battery replacement method can reduce waste in the number of used batteries, it naturally without having to comply with new EU regulations change iPhone battery design.
