NawaTechnologies officials said that after the incorporation of carbon nano-supercapacitors, the charging speed of lithium batteries has been significantly improved, and the weight has also been significantly reduced, which can increase cruising range and performance output when applied to electric vehicles. The start-up company in Marseille, France, is developing a new type of battery, which is believed to bring disruptive changes to the traditional electric vehicle industry after its introduction.(Lithium - Ion B

Researchers at the University of Akron have developed Mn3O4/C hierarchical porous nanospheres and used them as anode materials for lithium-ion batteries. These nanospheres have high reversible specific capacity (1237mAh/g when the current is 200?mA/g), excellent stability (425mAh/g when the current is 4A/g) and extremely Long cycle life (current is 4A/g, no obvious capacity decay after 3000 cycles of use). In theory, transition metal oxides are promising anode candidates due to their high capacity and low cost.

Recently, the Ministry of Industry and Information Technology has publicly solicited opinions on the "Requirements for the Review of Access Licenses for Road Motor Vehicle Manufacturers (Draft for Comment)" and the "Requirements for the Review of Access Licenses for Road Motor Vehicle Products (Draft for Comments)", proposing that enterprises should build used power batteries Stable recycling channels ensure the safe recycling of used power batteries. In the process of scrap recycling of powe

According to foreign media reports, researchers at Japan's National Institute for Materials Science (NIMS) claim that nanoporous, amorphous silicon film anodes exhibit excellent cycle stability and extremely high lithium-ion storage capacity: in After 100 times of charge and discharge, it is 2962mAh/g (2.19mAh/cm2). The NIMS team combined nanoporous amorphous silicon films with inorganic solid electrolytes to address the problem of capacity fading. The nanoporous structure can accommodate the volume change o

When a new car is launched, of course I am talking about electric vehicles, there are often such introductions: "Quick charge, 80% charge in half an hour, 200 kilometers of battery life, completely solve your mileage anxiety!" Fast charging, commercial vehicles are used to improve equipment usage Efficiency, which passenger cars use to address range anxiety, is constantly approaching the time to add a tank of gas. There is a tendency to become standard. Today, let’s dig and dig the fast charging met

Today's Battery Magazine - China Battery Alliance News On April 24, Dow's technical announcement disclosed that it plans to acquire the remaining shares of its holding subsidiaries, Jiana Energy and Qingdao Haoxin, for a total transaction price of 1.503 billion yuan. The announcement shows that Jiana Energy, as an important domestic cobalt product supplier, has been focusing on the production of cobalt salt products through the hydrometallurgical process for more than ten years since its establishment, a

At the "2018 Yokohama People and Vehicles Technology Exhibition" that ended not long ago, Toshiba Materials exhibited a lithium-ion battery that uses purple tungsten oxide as the negative electrode material, which can realize ultra-fast charging. The applications of this kind of battery range from automobiles, micro/mild hybrid electric trains, elevators, uninterruptible power supply UPS to high current power supplies, with obvious application advantages and wide coverage. As a pioneer in the field of lit

On June 5, Tesla's global sales director Ren Yuxiang disclosed the company's plan to build the company's first factory outside the United States in Shanghai, China. Tesla CEO Elon Musk also said at the conference that he is closely related to Tesla's cooperation in the United States. Unlike the factory, the new one will produce both batteries and assemble vehicles. Affected by this, the stock prices of Tesla-related companies immediately launched an upward offensive. On the same day, the lithium

Recently, according to South Korean media reports, the research team of Samsung Electronics General Technology Institute has successfully developed a new battery material "graphene ball", which is 45% higher than the charging capacity of existing lithium-ion batteries, and the charging speed is increased by more than 5 times. The researchers found that after adding silica to the high-strength, high-conductivity graphene material, graphene can be synthesized in large quantities, and the synthesized grap
