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

Oil giant BP said recently that its venture capital fund has invested $20 million in Israeli company StoreDot. StoreDot has developed a battery system that can charge an electric car in the same amount of time it takes to fill a gas tank. BP Ventures said the investment is part of a push to develop electric vehicle technology and infrastructure. Tufan Erginbilgic, CEO of BP Downstream, said: "Ultra-fast charging is at the heart of the company's electrification strategy. We are committed to being the

In the new energy vehicle industry, technical problems such as difficult charging and long charging time have always been one of the obstacles to the promotion of electric vehicles. In the case that the charging facilities cannot fully meet the demand, the core problem of all this is that the charging technology of electric vehicles is not up to standard and cannot meet the requirements of fast charging. Power vehicles that can meet fast charging have become a dominant demand in the industry.（Lithium - Ion Battery

Last year, the global release of the timetable for the ban on the sale of fuel vehicles made people realize that the era of new energy vehicles is coming, and why pure electric vehicles, plug-in hybrids, fuel cell vehicles, etc. have become the future in just a few years the main theme? On the one hand, it is the support of global strategies, policies, etc., on the other hand, the continuous improvement of power battery technology, longer battery life and shorter charging time, which are directly related to the com

Inspired by the biological spine structure, GuoyuQian et al. of Columbia University developed a flexible lithium-ion battery that maintains the advantage of high volumetric energy density while ensuring good flexibility. The basic structure of a flexible battery can be divided into a backbone and branches connected to the backbone. These branches are wound around the backbone to form a structure similar to an animal's vertebrae, and the backbone is connected to the external circuit. This structure not only e

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

Thanks to the development of new energy vehicles, power batteries are in the midst of rapid development, and the development of new energy vehicles also puts forward higher requirements for the performance of power batteries. By 2020, the specific energy of the new lithium-ion power battery cell will exceed 300wh/Kg, and by 2025, the specific energy of the new system power battery cell will reach 500wh/Kg. Driven by both policy and market, power batteries are bound to develop in the direction of high energy dens

It was learned from the Qingdao Science and Technology Bureau that the high specific energy solid-state lithium battery technology project led by the Qingdao Institute of Bioenergy and Processes of the Chinese Academy of Sciences was shortlisted for the new energy vehicle key project of the Ministry of Science and Technology's 2018 National Key R&D Program, and will receive 23.63 million yuan from the central government. In 2014 and 2015, the Municipal Science and Technology Bureau successively approved

According to the "China Nonferrous Metals News" report, at the sixth council meeting of the China Chemical and Physical Power Industry Association, Secretary-General Liu Yanlong particularly emphasized the layout of lithium battery ternary materials patent technology. He pointed out that under the general trend of ternary lithium batteries, especially high-nickel ternary batteries, many domestic cathode material companies are facing huge foreign patent fees in their development. So, what is the current
