Development of China's lithium-ion battery breakthrough
Major IT projects in Beijing, "Li-ion battery cathode material of lithium manganese oxide of the industrialization of technological development" technical problems at one stroke to capture the world in the development of new lithium-ion toshiba battery to achieve a major breakthrough for Beijing 2008 Olympic Games electric buses have technical support. May 10, the project passed the acceptance of the Beijing Municipal Science and Technology Organization.
"Lithium-ion battery cathode material of lithium manganese oxide of the industrialization of technological development" project is the Beijing Municipal Science and Technology Commission on the project in October 2002 and three million yuan in support of UNITA by CITIC Technology Co., Ltd. Solid-Lee power to implement major projects. After nearly two years, the project team developed with independent intellectual property rights of the lithium-ion batteries key materials required for the synthesis of lithium manganese new technology. According to project leader of UNITA solid CITIC Lee, general manager of Power Technology Co., Ltd. introduced its, the process to resolve the international Lithium manganese spinel structure synthesis of the key technical problems, through the multi-element doping, morphology control technology solutions such as a manganese lithium charge-discharge cycle stability of the world-wide technical problems worse. Through the implementation of the project, but also independently developed a set of large-scale production installations, and in 2003 took the lead at home and abroad, an annual output of 200 tons and built a superior electrochemical performance of lithium manganese oxide of the production line to produce a good thermal stability and electrochemical superior performance of lithium manganese oxide materials.
At present, solid UNITA CITIC Technology Co., Ltd. Lee Power has begun the production of manganese steel 10Ah lithium power lithium-ion battery and miner's lamp battery ,5-20Ah small and medium-sized aluminum-plastic packaging film lithium manganese lithium-ion battery power ,20-150Ah high-capacity aluminum-plastic packaging film lithium-ion battery power and high-power batteries for electric tools. Which, 10Ah Lithium Manganese steel power batteries and plastic film packaging 100Ah Lithium Manganese battery power through the national 863-based detection of the test battery.
Beijing Science and Technology Commission, in accordance with the requirements of UNITA CITIC Technology Co., Ltd. Solid-Lee power electric cars for the Beijing Olympic Games projects 100Ah high-capacity lithium manganese toshiba tecra a9 battery, toshiba tecra m3 battery, toshiba tecra a2 battery load test has been completed and has been running for more than 10,000 km, battery condition good. It is learned that this electric buses short charging time, charging three hours to reach 95% of the volume of each charge to run a 200-400 km per charge battery capacity will be 500 times attenuation of 8.3%, its operating costs only fuel cars 1 / 5. Beijing 2008 Olympic Games is the minimum goal of 1000 for electric buses, the battery output alone on the RMB 5 billion yuan. According to Fan Boyuan, vice mayor of Beijing said in Beijing the first batch of 30 electric buses, this month is expected to be issued by National Development and Reform Commission and the Ministry of Public Security of the license. Next year, Beijing is expected to have 200 electric buses put into use.
To lithium manganese oxide for the positive momentum of high-capacity rechargeable battery, the future is expected to quickly be applied to land, sea and space, such as mobile power, emergency power, uninterruptible power supply as well as large-scale urban night-time electricity storage device. UNITA CITIC Technology Co., Ltd. Solid-profit Power has developed several hundreds of kilowatts of energy to me (as a lithium manganese oxide cathode material) new products, non-renewable energy resources to create a full use of new ideas.
In the course of the development of electric vehicles, cheap and durable power of mobile security is the most urgent task. For more than a decade, many countries are committed to fuel cells and nickel-metal hydride batteries and lithium ion secondary battery research and development work. But the key is still faced with many difficult technical problems, so the realization of electric vehicles as a result of the industrialization process of the development of motive power can not achieve a breakthrough. A large number of research results show that not only affect the battery cathode material for battery safety, but also about the price of the battery. At present, the lithium ion secondary battery using the cathode material is lithium cobalt, but the lack of China's cobalt resources, the main dependence on imports, and its poor stability, easy to heat decomposition of the gas release or explosion resulting in combustion. Therefore the use of low-cost synthesis of a stable performance and good safety performance cathode material to the development of battery electric vehicle industry is essential.
As early as in the "Ninth Five-Year Plan", the "advanced batteries and their materials industries," Ministry of Science and Technology has been included in major scientific and technological special. "Tenth Five-Year" period, 863 made clear in the new energy conversion and energy storage materials to place greater emphasis on special studies and support than high-energy, high-capacity, long-life lithium-ion battery materials, and so on four topics, and the establishment of major projects for electric vehicles . Beijing bid to host the 2008 Olympic Games has made lithium-ion secondary batteries and related technology development and application to be heard, in 2002, Beijing Science and Technology Commission, the approval of 10 periods, "lithium-ion battery cathode material for lithium manganese industry technology development" as a major science and technology projects officially approved by the UNITA CITIC Technology Co., Ltd. Solid-Lee is responsible for the power of lithium manganese oxide materials, as well as research and development of battery power.
At present, UNITA CITIC Technology Co., Ltd. Solid-profit Power Lithium manganese production materials have already entered the domestic and international market, some domestic production of lithium-ion secondary batteries have begun to use the bulk of UNITA CITIC Technology Co., Ltd. Solid-profit Power Lithium manganese production products toshiba tecra m5 battery, toshiba tecra m2 battery, toshiba tecra m6 battery, In addition, South Korea, France, the United States is the trial of the project lithium manganese products.
Japanese researchers made in serum glucose as a "fuel" the battery
Tohoku University Graduate School of the leadership of Professor Yan research team recently announced that they developed the use of bovine serum glucose in the fuel cell power generation.
According to "Asahi Shimbun" reported that Nishizawa and others used in experiments, a battery made from the carbon electrode. The electrode is equivalent to RMB 1 coin size, its surface coated with serum glucose able to break down the enzyme. Such as enzymes break down glucose response will appear after the e-directional flow, resulting in current, power output equivalent to 0.2 mW.
Caesar said that the pacemaker, such as blood glucose testing devices implanted in the human body in the battery life through the end of surgery to replace the battery. New fuel cell is expected for the implanted device similar to a more sustainable to provide adequate power to reduce or even avoid the "change battery" operation.
Advent of new types of nuclear batteries can be used for 12 years
American scientists announced that they have successfully developed a new type of nuclear batteries, its power is 10 times that of similar cells, but also for the use of at least 12 years.
According to the United States "life science" Journal of May 13 reported that engineers from the United States to thank the University of Rochester research team led by newly developed nuclear batteries, lies in its unique thermoelectric conversion for the silicon wafer. They carried out the transformation of its surface, carved numerous wide-1-micron, 40 micron deep hollow point, so that the response of a three-dimensional environment has greatly increased the power generated, once the battery power increased 10 times. As this nuclear battery would not cause radiation do not have to worry because the metal nuclear toshiba tecra m9 battery, toshiba tecra s3 battery, toshiba satellite a55 battery sealed radioactive energy enough to react completely closed.
