Throughout the current new energy vehicle market, there are many types, but the key core component is the energy storage equipment of the vehicle. The battery energy storage capacity is the biggest bottleneck in current research: on the positive electrode, the energy storage capacity of sulfur is larger; on the negative electrode, the energy storage capacity of silicon and metal lithium is larger, this problem needs to be determined by the selection of electrode materials. to solve. Therefore, it is necessary to tr

Fisker lost the first time on lack of core technology, what about the second time? At this year's CES, American luxury electric company Fisker exhibited its latest pure electric vehicle - Fisker EMotion. Does it sound a little familiar? However, this is not the Fisker acquired by Wanxiang Group. Henrik Fisker, a car designer, has experienced the bankruptcy of his own brand, the failure of the first model, the Fisker Karma, and the relationship with Tesla. Now, he has re-founded a new company in his own

But what the author wants to emphasize is that the achievements of these forward-looking technologies still have a considerable distance from industrialization. Of course, this does not mean that the research of domestic experts is out of industrialization, but that the lithium battery itself is still far from the next-generation battery technology. The current domestic consensus is that in the near future, 300wh/kg will be achieved through high nickel ternary cathode and silicon carbon anode; It is to develop l

Acting low-key but enjoying a good reputation in the lithium battery industry, this lithium battery equipment company released a big move at the 2018 CIBF battery exhibition. At the exhibition, Shenzhen Kerui Technology Co., Ltd. (hereinafter referred to as "Kerui Technology") mainly exhibited two types of equipment: winding machine and soft package vacuum packaging machine. Among them, the winding machine launched by Kerui Technology has attracted a lot of attention.(Lithium - Ion Battery Equipment)

Official data shows that the energy density of square shell cells in the Ningde era has reached 240Wh/kg at this stage, and the technical plan is to increase the cell energy density to 300Wh/kg by 2020. While improving the energy density through the 811 ternary positive electrode + silicon/carbon hybrid negative electrode, the cycle, high temperature performance, cost, safety, etc. have to be sacrificed, and the production process and environmental requirements are also relatively harsh. People familiar with the

Wu Yang, CEO of Weihong, introduced that when Weihong began to focus on the research and development of electric vehicle power systems in 2008, it established 10-minute fast charging (electric vehicle mobility guarantee), long life (realizing electric vehicle life cycle circulation) , non-combustion (to ensure that electric vehicles will not spontaneously ignite without warning) three major elements, "ten-minute fast charge" and "long life" battery technology has more than 10,000 sets of battery

A few days ago, the relevant leaders of Changxing County, Huzhou City, Zhejiang Province visited Zhejiang Chaowei Beiterui Technology Co., Ltd. to inspect the progress of the graphene alloy project, and highly affirmed the construction progress and standardized management of the project. The graphene alloy project of Zhejiang Chaowei Betterui Technology Co., Ltd. was established to undertake the advanced technological achievements of the cooperation between Chaowei Group and international first-class scientific

Recently, researchers at Linköping University in Sweden have successfully developed a new type of fuel cell using lignin from trees as a raw material. Unlike batteries that use small molecules such as methanol and ethanol as fuel, this process does not generate carbon dioxide, not only is the raw material green and environmentally friendly, but also the product achieves zero carbon emissions. Lignin is an important structural material for plants and algae. It is common in bark or wood. It is one of the by-p

At present, there are two main production processes of aluminum-plastic film for lithium batteries at home and abroad: the dry production process represented by the Japanese Showa and the thermal production process represented by the Japanese DNP. The dry production process was jointly developed by Japan Showa and Japan Sony. Since Sony's electrolyte is solid and does not require the electrolyte resistance of aluminum-plastic films, adhesives are used in Japan's Showa dry process, and the adhesives The e
