It is reported that the joint research team has developed a proton conductor for fuel cells. The conductor is based on polystyrene phosphoric acid and can maintain high proton conductivity at up to 200 ℃ and without water. The researchers of the team are from Los Alamos National Laboratory, the University of Stuttgart, the University of New Mexico and Sandia National Laboratories. Fuel cell is a promising technology, which can convert hydrogen into electricity through electrochemical process, and only drain wate

Nickel cobalt manganese is widely used because of its high specific capacity, long cycle life, low toxicity and low cost. Nickel is an important component in the redox energy storage of cathode materials for lithium ion batteries. How to effectively improve the specific capacity of materials by increasing the nickel content in materials is one of the current research focuses. 1 High nickel ternary material Generally speaking, ternary cathode materials with high nickel mean that the mole fraction of nickel in

The progress of science and technology has added the word "smart" to the name of glasses, watches, necklaces and other items we wear. Even the mobile phone used to make calls and send messages has become a smart phone. It is true that smart devices are more versatile, but is intelligence more convenient? I don't know anything else, at least not in charging. At present, the battery life of mainstream lithium batteries is only a few days, and wearable devices are generally small. The energy density o

According to foreign media reports, there is nothing more suitable for powering smartphones or Tesla than lithium batteries. Since its first launch in 1991, rechargeable lithium batteries have become daily scientific and technological equipment and electric vehicles. General standard of vehicle power supply. Data shows that most of the more than 3 million electric vehicles in the world are driven by lithium battery batteries. However, as the world moves towards the future power era, it is clear that we need better

The automobile industry is the largest industry in human history, bearing countless output value and employment. Today, the efficiency of internal combustion engines cannot be greatly improved. Whoever gets the first chance in the field of new energy will win tomorrow. Naturally, every country does not want to lag behind. Different countries have different technological reserves and different technological routes, and their response methods are different.(Lithium - Ion Battery Equipment) Among them, Toyota deser

Last year, the domestic car market was in a recession. There were many sad and desolate places. Many joint ventures with outstanding performance also turned from rising to falling. However, in such a bleak environment, new energy vehicles are still rising against the trend, with production and sales exceeding one million and becoming the most dazzling star in the market. The rapid development of new energy vehicles largely benefits from the substantial improvement of power battery performance. It has been 10 yea

"Lithium battery is the core component of new energy vehicles. Recycling of retired batteries should be an important part of the whole life cycle of power batteries, but it is relatively extensive in China at present. If we do not pay close attention to the research and development of advanced recycling technology of power lithium batteries, it will seriously restrict the development of the battery industry and even the new energy vehicle industry." Recently, Fei Weiyang, an academician of the CAS Memb

The project of "Power Battery Cascade Utilization Heterogeneous Compatible Energy Storage Power Station" jointly developed by Anhui Risek, a subsidiary of Chery Group, and the School of Environmental and Chemical Engineering of Shanghai Electric Power University, has successfully solved the technical bottlenecks in the compatible application of power batteries of different brands, aging degrees, and structures. Taking the retired power battery as the energy storage carrier of the substation, continuing

A few days ago, Dow Technologies, which has a deep layout in the field of lithium battery materials, announced that it plans to invest in the establishment of Guangdong Dow Picea Hydrogen Energy Technology Co., Ltd. The new company is mainly engaged in the development and sales of materials such as hydrogen fuel cell membrane electrode (MEA).
