Another major development, the world's first automatic production line for lithium metal batteries opened in Hefei, Anhui Province.

Thanks to CTOnews.com netizens grass Luo Yuzi, snow season _ clues delivery! CTOnews.com Sept. 20 news, with the continuous development of electric vehicles, electric vehicle-related industries are also making rapid progress. According to the official WeChat of Hefei, at the "Lithium Battery Innovation Technology Forum" of the 2022 National Volkswagen Entrepreneurship Innovation week held in Hefei yesterday, Mengwei Technology was officially launched at the lithium-metal battery automatic manufacturing line and Z21 innovation laboratory in Hefei Economic Development District.

It is reported that this is the first special production line for automated lithium metal battery manufacturing in China and even in the world, and it is also another major progress in the large-scale production of China's independent research and development of a new generation of power battery technology enterprises. Professor Zhang Yuegang of Tsinghua University said at the event that with the transformation and upgrading of global energy, the demand for battery energy density is increasing. As an important development direction of innovative breakthrough technology in the battery industry, lithium metal battery is expected to more than double the mileage of electric vehicles in the future.

Professor Zhang Yuegang said that the full opening of the Lithium Metal Battery Automation Manufacturing Line of Mengwei Technology shows that China's batch delivery capability of 500Wh/kg high-end energy power battery products has been in the leading position in the world, realizing the breakthrough of lithium metal battery from the laboratory stage (TRL3) to the product batch delivery stage (TRL6-8).

CTOnews.com learned that public data show that lithium batteries can be divided into two categories: lithium-metal batteries and lithium-ion batteries. Among them, lithium-metal battery was first proposed and studied by Gilbert N. Lewis in 1912. Its safety, specific capacity, self-discharge rate and performance-price ratio are better than lithium-ion battery, but due to its own high technical requirements, only a few countries are producing this kind of lithium-metal battery.
