GM new battery car

Yesterday, by General Motors (China canon bp-617 battery) Investment Co., Ltd. and Tianjin University, co-sponsored the “advanced automotive energy-saving emission reduction technologies” show exchange in Tianjin University. The event of “leading technology, harmonious power” as its theme, to fully showcase the latest technology of the international automobile industry and General Motors to achieve sustainable transport development blueprint drawn up, and its debut in Tianjin, GM’s latest scientific research – Hydrogen moving on the 3rd of fuel cell vehicles.

In the technology demonstrator, the General Motors Corporation has also demonstrated the “Shenxin can” hybrid passenger cars and Buick LaCrosse sedans canon bp-711 battery, on behalf of its strategic vision, transitional solutions and recent developments.

Israel made of low-cost solar photovoltaic cells cost than traditional silicon solar cells by 40%%

Israel’s Bar Ilan University nanotechnology expert has developed a new type of low-cost photovoltaic cells, the photoelectric conversion rate of traditional silicon solar cells are equivalent, but can reduce costs by 40%. Such photovoltaic cells is the use of nano-technology canon bp-911 battery design, and distributed in the plastic plate by sponge-like micro-nano-dot matrix composed of glass installed in the conductive metal wire constitute a fundamental part. In order to enhance the ability to absorb sunlight, the researchers injected to the semiconductor materials, organic dye inside.

Bar Ilan University, Nanotechnology Zabban Professor Director of the Institute, initially they have developed photovoltaic panels photovoltaic cells by small matrices, each photovoltaic film is only one square centimeters, due to photovoltaic films is small, the space between the plate and sheet and more sunlight in the above can not be converted into electrical energy, the conversion efficiency is relatively low. In view of this situation, they will each light the area of solar cells increased to 100 square centimeters canon bp-930 battery, the photovoltaic cell matrix markedly enhanced the ability to capture the sun.

Zabban professor said that in the solar energy research and development, the cost is an important factor. To make solar cells are widely accepted to be its production cost is lower than conventional fossil fuels, while the infrastructure cost and allowing developing countries to accept them. Their results of this study can effectively reduce the cost of photovoltaic cells for solar cells occupy a much broader market to open up the road. In addition of toshiba satellite a10 battery, he is also studying the reduction of platinum use of solar cells in order to further reduce costs.

At present, the Jerusalem a solar energy company is working with the Bar Ilan University, promoting the commercialization of solar photovoltaic cells. They hope that the next five years with toshiba satellite a65 battery , photovoltaic cells can enter the market successfully.

New material extended lithium-ion battery applications

New material extended lithium-ion battery applications

The Dell Inspiron E1705 Battery problem of shortage of resources for the Cobalt, you can replace the lithium cobalt nickel manganese cobalt cathode material for lithium also successfully researched. HUANG Xue-Jie said: “This material is a layered oxide cathode material, in the early 1980s Jipi the discovery, synthesis difficulty is much higher than lithium cobalt oxide, crystal type control is particularly difficult, has not been applied, we have developed a unique precursor lithium synthesis and processing technology, 80% of the cobalt has been replaced by manganese and nickel, and to achieve the control of grain size, synthetic materials, a reversible capacity of 165mAh / g, higher than that of lithium cobalt oxide 10%, cycle life to 500 times. ”

In addition, the project team has also developed a Dell Latitude D510 Battery proprietary aluminum oxide surface modification technology for modification into the spinel lithium manganese oxide materials, to produce reversible capacity of 107mAh / g, 55C cycle 200 times the capacity retention greater than 90%, better than similar products in the international level, is the first hybrid battery can be used for a high-power lithium-ion battery materials, protects the major projects of high-power electric vehicles, lithium-ion battery the smooth progress of the project. Huang Xue-Jie said: “In 2004, Beijing Xingheng this material-based high-power hybrid cars with lithium-ion batteries fully passed the 863 major projects planned electric car testing the unity of the organization, the power to reach 1200W / kg, safety, cycle, high – low temperature performance and other tests all pass, this year is expected to reach 1800W / kg and through UL certification testing. In addition, Star Constant 10Ah high-energy type and 7.5Ah high-power lithium-ion battery, through the United States UL safety test, becoming the first Chinese mainland through UL-certified Li-ion power Dell Latitude D610 Battery, battery-enter the international market for this kind of paved the way. ”

Lithium-ion battery anode material is lithium-storage function, to assume a key material, the importance should not be ignored. Huang Xue-Jie description: “The current commodity lithium-ion dell latitude d600 battery used in the graphite anode materials were reversible capacity of 300-340mAh / g. In this regard, we have developed a nano-hole hard carbon balls, Lantern structural composite anode materials, the current reversible capacity of composite anode materials has already reached 600mAh / g. At the same time developed a graphite nanofiber conductive additive, can increase the power density of high-power batteries. ”

He told reporters that only the positive and negative material embodies the application of domestic invention patent 21, four of which are authorized and have been two international invention patents.

Huang Xue-Jie said in conclusion: “China’s lithium-ion battery industry has developed very rapidly, has now become the world’s second largest producer of lithium-ion battery, second only to Japan. Will we have to do is the development of large lithium-ion battery, new materials, in reducing the the cost, we must also make dell latitude d610 battery safer, live longer. “
