On April 17, the 7th Automotive Power Battery Recycling and Secondary Battery Recycling and Sponsored by China Battery Alliance, China Electronics Energy Conservation Technology Association Battery Professional Committee, China High-Tech Industrialization Research Association, Tsinghua University, and Beijing Institute of Technology The Symposium on Recycling Technology was held in Beijing Guoneng Huang, deputy general manager of Dongguan Xinmao New Energy Technology Co.

Trillion (002256) announced the new shares, the company has been in Shanghai on June 11 in lithium original shareholders signed on the lithium in the Shanghai industrial co, LTD.

Morning of October 23, Huawei announced in the UK and the application of graphene, collaborators at the university of Manchester to jointly develop the next generation of high technology in the field of ICT The project cooperation beginning for two years, the research how to breakthrough in the field of graphene in consumer electronics and mobile communication devices.

Introduction of iron lithium battery The iron-lithium battery is a kind of battery in the lithium battery family, and the positive electrode material is mainly lithium iron phosphate material, which is also referred to as lithium- iron-battery Compared with traditional lead-acid batteries, lithium-ion batteries have significant advantages in terms of operating voltage, energy density and cycle life.

Graphene, hot material in the scientific community, the industry is new bestow favor on, but there has been no industrial preparation method of quick and high safety Professor in the department of zhejiang university high polymer superb team, to avoid the drawbacks of existing methods, preparation of single-layer graphene found a "green" route, process fast, low cost, no pollution, is suitable for large-scale preparation of industrialization.

Lithium cobaltate battery has stable structure, high specific capacity and outstanding comprehensive performance, but its safety is poor and the cost is very high It is mainly used for small and medium-sized batteries.

With the introduction of energy-saving and environment-friendly economy, new energy vehicles are popular in the market, but their safety has always been a controversial topic In particular, the relationship between power batteries and new energy vehicles has always been controversial.

A few days ago the reporter understands, yangzi petrifaction takes the lead in domestic implementation lithium battery diaphragm special makings industrialized production, broke the situation that this industry relies on entrance completely, undertaking market promotion This marks that the lithium battery industry chain in nanjing is further improved, and the power of industrial development is stronger.

Battery life of pure electric vehicle, if it is long-life lead-acid battery, generally in 15-2 years, if it is lithium iron phosphate battery theoretical life in 7-8 years.

Science and Technology Daily, Beijing, April 23 (Reporter Linlin Fang): According to a recent research report published in the journal Science, researchers at the Photonics Institute of Photonics (ICFO) in Barcelona have created the latest use of graphene to limit light record They "squeezed" light into a single atomic-sized space, and the results helped to develop ultra-small optical switches, detectors and sensors.
