Lithium-ion battery has annual sales of 27 billion U.S. dollars;

Lithium-ion battery has annual sales of 27 billion U.S. dollars; lithium-ion battery is no doubt the market leader in rechargeable batteries. However, people always want to do even better. Now, scientists report that they use nano technology can greatly enhance the lithium-ion battery energy storage capacity, or maintain the existing level of energy storage conditions greatly reduce the battery weight. The new results can bring smaller notebook computers, dell laptop battery longer trips such as a large number of electric vehicle applications.

In traditional rechargeable batteries, with positively charged lithium-ion stored in carbon-based anode, with the battery discharge will flow to the cathode. This technique has the advantage of carbon remain after repeated charge-discharge light and durable, but the disadvantage is six carbon atoms can support a lithium ion. Recently, researchers try to make crystal silicon anode, each silicon atom can support about four lithium atoms, in theory, would enhance the efficiency of energy storage.

In 2007, Stanford University materials scientist Yi Cui’s team is led to do so. They use crystal silicon Nan wire anode production, this material is very thin, so the losses caused by inflation and less flexible. This battery can store 10 times the conventional lithium-ion battery charge level. But the problem is crystal material after repeated charge-discharge damage, and eventually breaks, the battery will be damaged.

Therefore, in a recent study, Yi Cui’s team covering the outer layer of amorphous silicon with carbon nano-line replacing the fragile silicon Nan wires.dell W0465 battery, The inherent stability of the carbon core made of amorphous silicon with a full staff to make lithium-ion. The result of this new carbon – silicon mix anode has a 6-fold in the traditional full charge capacity of carbon anode, the early tests, they also compared the performance of all-silicon anode is more stable.dell INSPIRON 2650 battery, dell 1G222 battery, dell BAT3151L8 battery,dell Latitude X300 battery, dell W0465 battery, The results were published in an upcoming issue of the “Nano Letters” on. Using the results, the battery company will eventually be able to produce lighter, battery capacity, which is the key to the future manufacture of electric vehicles. Cui Yi pointed out, the battery company to keep the battery in under the weight increase of 50% of storage capacity.

University of Texas, material chemists, battery experts, Arumugam Manthiram speaks very highly of this achievement. But he also said that because of this new material must be with the battery in the other components together and confirmed that its cheap, safe, fast charge, so that the results will improve in the future, the extent to which the battery is not yet clear. “This is a very challenging task.” Manthiram said, “That is why such a slow progress in battery technology reasons.”

Bosch solar energy in its further expansion of solar energy production facilities, officially opened the new Arnstadt, dell Latitude X300 battery, Thuringia, crystal silicon solar cell manufacturing plant. 12,000 square meters of facilities can provide 10,000 solar cells per hour and the annual output capacity of 90 million U.S. dollars.

Bosch Solar CEO, said, we will cover the complete chain of crystalline silicon industry, which not only makes our products the best performance and quality costs can be reduced so that we can have greater technical potential.

With the Arnstadt plant is completed, Bosch aims to triple to about 630MWp, thus greatly promoting its growth strategy. Expansion of its facilities will be completed in 2011, when the R & D center and the main body of the new administrative building will be completed.

The building opening ceremony will be held in summer 2011. By 2012, Bosch will invest about € 530 billion and create 1,100 jobs.

With the lithium battery market demand, Foshan lighting in the field of new energy lithium batteries are increasing the pace of investment, the company today announced a number of investment plans in this area.

Foshan Lighting management intends to cooperate with other investments, dell 1G222 battery, build factory in Foshan, 100 000 000 smart security when iron production and integrated lithium battery PACK base controlled by the Foshan lighting. Battery production base is expected to total 261 million Yuan investment, investment in two phases. After completion expected sales revenue 6.5 billion after-tax profits of 075 million Yuan, the project construction period is about 8 months; the project recovery period is about 3.5 years. Currently, other investors have not yet determined.

Meanwhile, the Foshan Lighting invested lithium cathode materials. Hefei Li Xin recently with many companies such as Energy Materials Co., Ltd. signed an agreement to jointly initiate the establishment of Qinghai Lithium Cathode Materials Co., Ltd. according to the Buddha. The new company registered capital of 50 million Yuan, Foshan lighting to 25.5 million Yuan in cash investment, accounting for 51% of the shares. dell INSPIRON 2650 battery, dell 1G222 battery, dell BAT3151L8 battery
dell Latitude X300 battery, dell W0465 battery,The initial design of the new scale of production is 2000 tons / year, estimated investment of 100 million Yuan.

Foshan Lighting also said the company is working with Taiwan and Hong Kong Cheung Industrial Co., Ltd. will discuss issues related to cooperation, both sides will jointly invest to establish joint other investors lithium iron phosphate cathode material manufacturers, lithium battery manufacturer; and intend to battery management electronic control systems and electric vehicle technology system solutions cooperate together in conjunction with other investors established in Foshan,dell INSPIRON 2650 battery, pure electric vehicle production base.

Semi-annual report released at the same time show, Foshan lighting in the first half realized main business income of 818 million Yuan, an increase of 10.7%; net profit attributable to parent company, owner of 80.8178 million Yuan, up 13.54 percent year on year. Steady growth in core business revenue, gross margin was stable. Shares in the second quarter were China Growth Fund huge advantage holdings.
