In the next five years, the lithium ion battery market for new energy vehicles will see an average annual growth rate of about 50% The technological progress of lithium ion battery mainly comes from the progress in the innovation, research and application of key battery materials.

The key factors for Chinese electric cars to have a bad start are the cruising journey, charging speed and safety, all of which are caused by the poor technology of power lithium battery, so they can be regarded as the three technical bottlenecks of power lithium battery packWhat are the technical bottlenecks for lithium-ion batteries?I.

A team of New York university scientists have developed an easier way to test a battery pack, which is usually dismantled to see its structure and damageRise of 3 c products is growing with electric cars, people more and more need to safe and efficient battery, the battery detection way is still stagnant, professor of chemistry at the university of New York Alexej Jerschow, said the current can only a few tools under limited conditions, to diagnose without causing damage to the battery, the team developed a new type of machine, can with noninvasive technology provides more rapid and scalable detection method.

1, LiCoO2In the current commercial lithium ion battery, the layered structure of LiCoO2 is basically used as the anode material Its theoretical capacity is 274mAh/g, while the actual capacity is about 140mAh/g.

On the one hand, safety concerns, on the other hand, technical development concerns, the development of ternary lithium battery encountered obstaclesThe debate over ternary lithium batteries continues to festerOn January 24, zhang xiangmu, director general of the equipment industry department of the ministry of industry and information technology, said at the "development and breakthrough of power battery" theme summit of China electric vehicle committee of 100 in 2016 that the risk assessment of three-yuan lithium battery will be carried out.

Recently, glencore released the first quarter of 2018 production report The following core data are integrated:In the first quarter of 2018, glencore produced 7,000 tonnes of cobalt from its own cobalt resources, up 11 per cent year-on-year.

BYD will intensify IGBT module of research and development, on the one hand, improve the electrical performance, meet the needs of new models, on the other hand extend IGBT module of the size of the market, to reach the foreign salesExperts say: in the future, BYD will increase the intensity of IGBT module of research and development, on the one hand, improve the electrical performance, meet the needs of new models, on the other hand, expand the IGBT module of the size of the market, to reach the foreign sales.

Battery technology changes with each passing day, the distance of the electric vehicle is also improving day by day! South Korean scientists have unveiled an electric car that can travel up to 300 kilometers on a single charge, has twice the range and can store up to four times as much powerThe state science and technology institute (GwangjuInstituteofScienceandTechnology, GIST) 10, announced that the GIST of materials science and engineering professor EomGwang - sup and electronic research laboratory at the Massachusetts institute of technology (MIT) postdoctoral researcher LeeJung - it hand in hand to cooperate, to develop the latest lithium battery, if compared with the products available in the market, the new lithium battery capacity reach four times, battery life is up to twice as much.

Released recently, the ministry's website declare the 304th batch of the announcement of road motor vehicle production enterprises and products, to declare a total of 73 enterprises of new energy automobile products 167 models, including pure electric products, a total of 68 enterprises, 153 model, plug-in hybrid product, a total of 7 families enterprise nine models, fuel cell products, a total of three family enterprise five modelsThe development of Chinese auto industry consulting company's chief, said jia xinguang, an analyst with rising fuel prices, national investment in hardware, such as charging pile, increased, as well as traditional fuel car preferential policy tightening and new energy automobile policy to relax, to let more and more purchasing power is transferred to the new energy, new energy boom or will the resulting from the beginning of the year.

Belgium's interuniversity microelectronics center has developed an innovative solid-state lithium-ion battery that can reach an energy density of 200 watt-hours per liter after being charged for two hours, British media saidThe intercollegiate microelectronics center is the world's leading center for nanoelectronics, energy, and digital technology research innovation, and a partner of EnergyVille, a research organization.
