863 plans to help power battery technology take off
As early as May of this year, some media learned from the Tianjin Science and Technology Committee that the National Li-ion Power Battery Engineering Technology Research Center declared by Tianjin Lishen Battery Co., Ltd. was approved by the Ministry of Science and Technology. Yesterday, according to relevant media reports, under the support of the “12th Five-Year Plan†National 863 Program, the “high-energy lithium-ion battery system and battery pack technology development†project has made significant progress.
It is reported that this project aims to develop high-energy lithium-ion batteries for lithium iron phosphate cathode materials, and carried out research on lithium-ion battery raw materials and battery cell design technologies, including domestic lithium iron phosphate cathode material testing and evaluation, and aluminum foil coating technologies. And diaphragm coating technology research. The project research and development product monomer battery energy density reached 138.6 watt-hours / kg, power density reached 915.6 watts / kg, after 1200 cycles of capacity retention rate of 94.1%. According to media reports, this result has already begun to be applied to mass production of 50 ampere-hour power type batteries.
Among them, the 38.4 volt/50 ampere-hour battery module for electric vehicles has an energy density of 121 watt-hours/kilogram and a power density of 800 watts/kilogram; the 345.6 volts/50 ampere-hour battery system has been applied to Chery's small pure electric cars and Austrian New pure electric sanitation vehicle.
Insiders pointed out that the project has also made important progress in domestic production and manufacturing equipment, and developed a fully automatic closed automatic feeding system, battery plate automatic lamination machine, large-capacity battery automatic injection machine, can automatically install The battery cells were converted into fixtures and an automated lithium-ion battery detection and matching production line was established, which greatly improved the consistency of the battery.
In view of this breakthrough, it has completed the important node of the 12th Five-Year Plan for the development of electric vehicle technology. Analysts expect this will lay the foundation for the industrialization of power batteries. At present, new energy vehicles are already a strategic emerging industry in China. Lithium-ion battery is the key component of new energy vehicles. The progress of its engineering technology is an important guarantee for the marketization of new energy vehicles. The “12th Five-Year Plan for Electric Vehicle Technology Development†once pointed out that it is necessary to firmly grasp the strategic transformation direction of the electrification of the automotive power system, focusing on key technologies such as batteries, motors, and electrical controls, as well as the key technologies for the entire vehicle of electric vehicles. And commercialization bottlenecks.
Tesla launches 90-second battery replacement service
According to overseas media reports, on Thursday evening in the United States, Tesla Motors showed a new type of device that allows an electric vehicle driver to fully charge the battery in about 90 seconds.
In the demo video, at the same time, the new device had replaced the battery for the Tesla S-Series, and a petrol car was refueling at a gas station in Los Angeles. During this period, the petrol spent 4 minutes, 99.83 US dollars to fill an 87 liters of fuel tanks, and the new equipment has already replaced the batteries for the two Tesla cars. According to the industry website "quartz net", the cost of replacing batteries is only 50 US dollars.
Tesla's chief executive, Alan Musk, introduced that the new equipment will certainly prompt people to consider buying electric cars for long-distance travel. He also promised that charging at the Tesla charging station is free at this stage and will always be free afterwards.
It is reported that there are currently 8 Tesla supercharging stations on the East and West coasts of the United States. The company announced the expansion of the charging station coverage area in May this year. By the end of June, the number of charging stations will increase to 3 times. In the fall, most urban areas in the United States will have charging stations. By the end of this year, corridors equipped with battery replacement technology will be established. Charging stations, covering 98% of the United States and Canada in 2015.
A-share lithium iron phosphate company is expected to be concerned
In the context of the significant progress made in the domestic “High-energy Li-ion battery system and battery pack technology development†project and Tesla’s 90 second battery replacement service storm, the future automotive battery technology will become the focus of the company’s development and the related phosphoric acid is expected to be relevant. Lithium and Lithium listed companies such as Huafang Textile, Jiangsu Guotai, Hengdian Dongxi and Shanshangufen are expected to receive the favor of funds.
Huafang Textile (600273): As early as 2010, in order to promote the follow-up R&D and production of Jiangsu Litian High Power Battery, Jiangsu Litian and Tsinghua University Institute of Nuclear Energy and New Energy Technology held equal consultations on technical services and joint R&D. Project and other issues signed the "Technology Service R & D Agreement." At the same time, the cooperation between the company and Shanghai Jiaotong University is also under the leadership of the Zhangjiagang City Development and Reform Commission, the Science and Technology Bureau and other departments, and finally reached the project's R & D cooperation intention.
