This morning, CCTV’s “Chao Wen Tianxia” broadcast, a globally competitive automated lithium metal battery manufacturing production line was officially opened in Hefei. The production line launched this time has achieved a major breakthrough in the energy density of a new generation of lithium metal batteries of 500Wh/kg. It is understood that this is the first dedicated production line for automated lithium metal battery manufacturing in China and even in the world.
Professor Zhang Yuegang of Tsinghua University said at the scene that with the global energy transformation and upgrading, the problem of “endurance anxiety” continues to push the boundaries of industry technology, requiring the battery energy density to continue to rise. Lithium metal batteries use pure metal lithium as the negative electrode, with ultra-high theoretical specific capacity and extremely low potential, which makes lithium metal batteries expected to more than double the cruising range of electric vehicles. It is an innovative breakthrough technology in the current battery industry. important development direction.
The full opening of the lithium metal battery automatic manufacturing line in Hefei shows that China ‘s batch delivery capacity of 500 Wh/kg high-end energy-type power battery products has taken the lead in the world, and realized the development of lithium metal batteries from the laboratory stage (TRL3) to Breakthrough in product batch delivery stage (TRL6-8). In the future, the products are expected to play a greater role in electric aviation, new energy vehicles and other industries. This dedicated production line put into operation in Hefei will also promote industrial upgrading and high-quality development, bringing more possibilities for the full activation of downstream application scenarios of new energy power batteries.
According to the electric knowledge, the special production line for 500Wh/kg automatic lithium metal battery manufacturing is realized by Anhui Mengwei New Energy Technology Co., Ltd. located in Feiqidi Science and Technology City, Economic Development Zone, Hefei City. In June last year, Anhui Mengwei New Energy Technology Co., Ltd. achieved a major breakthrough in the energy density of a new generation of lithium metal batteries of 500Wh/kg. Today’s dedicated production line for automated lithium metal battery manufacturing indicates that the company’s 500Wh/kg lithium metal battery has officially entered the stage of commercial mass production.
According to the electric know-how, in November 2021 , Anhui Mengwei New Energy Technology Co., Ltd. and Hefei Economic and Technological Development Zone signed an investment agreement for the new system power battery R&D and manufacturing base project, and the Mengweixin system power battery R&D and manufacturing base project officially settled in Hefei. As an explorer of lithium metal batteries, the launch of the power battery R&D and manufacturing base project of Mengweixin system marks that the world’s leading lithium metal batteries will take the lead in realizing large-scale mass production in Hefei.
The core team of Mengwei New Energy is composed of scientific and technological talents and industry elites from well-known universities and benchmarking enterprises at home and abroad such as Tsinghua University, University of Science and Technology of China, Chinese Academy of Sciences, etc. The team has the ability of lithium metal battery technology innovation and large-scale product manufacturing, and has a number of internationally competitive leading technologies in related fields such as lithium battery cathode and anode material design, electrolyte optimization, diaphragm modification, cell manufacturing and intelligent automated production. .
What is the concept of 500 Wh/kg? According to reports, taking the 2019 Tesla Model S/X long-range version with the longest cruising range currently on sale as an example, the mass energy density of the battery cell used is about 243 Wh/kg. The energy density of the battery is close to 500 Wh/kg, which is of practical significance, that is, it can nearly double the cruising range of the current electric vehicle .
Lithium metal batteries are new types of batteries with metal lithium as the negative electrode. The industry generally recognizes that solid-state batteries will be the next-generation battery technology, and solid-state electrolytes can only truly take advantage of their high energy density when combined with lithium metal negative electrodes. Anhui Mengwei New Energy has laid out the commercialization of lithium metal batteries in advance, actively opened up the “last mile” of laboratory and commercial applications, and plans to start the commercialization of solid-state battery technology to provide more high-quality and lightweight power for the electrification of aircraft and vehicles. In terms of safety, which the public is most concerned about, Mengwei New Energy’s lithium metal battery also has excellent performance. Whether it is challenging the limits of low temperature and high temperature, or safety tests such as steel needle puncture, Mengwei New Energy’s lithium metal battery technology has reached the international leading level.
