With the continuous development of electric vehicle , the electric vehicle-related industries are also making rapid progress. Especially in lithium metal battery .
According to public information, lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries . Among them, lithium metal batteries were first proposed and studied by Gilbert N. Lewis in 1912. Their safety, specific capacity, self-discharge rate and performance-price ratio are all better than lithium-ion batteries. However, due to its own high technical requirements, only a few companies in a few countries are producing such lithium metal batteries. 's "lithium metal battery" technology is an engineering breakthrough. It will greatly improve battery performance, enhance battery endurance, significantly improve the economic benefits of power storage, and promote the upgrade and transformation of consumer electronics product , which is of great significance to human life.
Yesterday, at the lithium metal battery innovation technology forum held in Hefei, Mengwei Technology's lithium metal battery automatic manufacturing line and z21 innovation laboratory in Hefei Economic and Technological Development Zone were officially opened. It is reported that this is the first lithium metal battery automatic manufacturing line in China and even the world, and it is another major progress in large-scale mass production by my country's independent research and development of a new generation of power battery technology companies.
Anhui Mengwei New Energy Technology Co., Ltd. was established in 2018. It is an innovative representative of China's new generation of high-energy density batteries. Starting from the actual application needs of electric aviation, it continues to innovate from multiple dimensions such as materials, processes, and structure. It has developed a high-energy density battery with lithium metal as the negative electrode, becoming the world's first hard technology enterprise to break through the technical bottleneck of lithium metal batteries and deliver 500Wh/kg in batches of high-energy density and high-security power batteries.
It is reported that is the first dedicated production line for automated lithium metal battery manufacturing in China and even the world. It is also another major progress in large-scale mass production by my country's independent research and development of a new generation of power battery technology enterprises. Tsinghua University Professor Zhang Yuegang said on the spot that with the global energy transformation and upgrading, the problem of "battery anxiety" continues to promote the technological boundaries of the industry and requires 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 more than double the range of electric vehicles, and are an important development direction of innovative breakthrough technologies in the current battery industry. The full launch of the lithium metal battery automation manufacturing line in Hefei shows that my country's batch delivery capacity of 500 Wh/kg high-end energy power battery products has ranks as the world's leading position, achieving a breakthrough in lithium metal batteries from the laboratory stage (TRL3) to the product batch delivery stage (TRL6-8). In the future, products are expected to play a greater role in industries such as electric aviation and new energy vehicles. This special production line put into production in Hefei will also promote industrial upgrading and the high-quality development of , bringing more possibilities to the full activation of downstream application scenarios of new energy power batteries.
PS: Seven major steps of lithium battery automation production line
Step 1: Battery raw material package enters the glove box from the feed compartment
Step 2: Battery raw material package is automatically scanned and weighed, and the weighed battery raw material package is automatically placed in the material conveying device
Step 3: The conveying device automatically enters the liquid injection cylinder for liquid injection
1 Step 4: The battery after injection enters the stationary cylinder 1, 2, 3, and sed
Step 5: The battery after rest enters the sealing cylinder to vacuum and seals
Step 6: The battery completed sealing will automatically be weighed secondary, and the unqualified products will enter the recycling transition compartment on the left for processing
Step 7: The qualified battery will be automatically sent to the discharge compartment
