Shuopu new material production line officially put into operation

The latest news shows that the first coating production line of Hunan Shuopu New Material Co., Ltd. (hereinafter referred to as "Shupu New Material") was officially put into operation in Changsha on March 1 this year. Then on March 15, the first diaphragm production line Installation begins and is expected to be officially put into operation in June.

It is reported that the total investment of the project is 5 billion Yuan. It is estimated that after the whole production in 2021, the annual output of lithium battery separator will reach 1 billion square meters, and the annual output value can reach more than 4 billion to 5 billion Yuan.

The construction of the second phase of the project, including one phase of investment of more than 900 million Yuan, covers an area of 187 acres, construction of four lithium battery separator production lines and eight coating production lines, with an annual output of 200 million lithium battery separator production capacity; the second phase of investment of 4.1 billion Yuan Construction of 16 lithium battery separator production lines and 32 coating production lines, with an annual production capacity of 800 million lithium battery separators.

"Separator is a key material for lithium batteries, and the market demand shows a blowout growth." Zhang Yang, general manager of Shuopu New Materials, said that although the cost of lithium battery separators only accounts for 15%-20% of the cost of batteries, it directly affects the safety of batteries, functional characteristics, and cycle life.

The data shows that the global diaphragm market has reached several billion square meters, with an average annual growth rate of 30%, but the domestic product supply accounts for less than 40%, and most of them are dry diaphragms. The high-end wet diaphragm still relies mainly on imports from Korea and Japan. The localization alternative space is vast.

In order to accelerate the nationalization of the lithium battery industry, shuopu new materials has introduced a full set of advanced wet production lines of lithium battery membrane from Korea and Japan, and hired high salary lithium battery membrane experts and technicians from Korea and Japan to fully control the production process and process and fully master the wet lithium ion battery membrane production process.

At present, Shuopu New Materials has fully overcome the production process of wet lithium ion battery separators and has many independent intellectual property rights such as water-based bonding technology, coating pore-forming technology, and membrane coating graft modification technology with the completion of the factory, Will be used soon for large-scale production.

"The company's high-end wet PE separator and ceramic coated diaphragm, the products are thinner and stronger, which makes the battery capacity larger and more consistent, which is in line with market needs and the development of the battery industry." Zhang Yang said. The company's series of products will break the monopoly of Japan and South Korea and reach the world's leading level.

At the same time, the company also set up a research and development center in South Korea to study the internationally advanced aramid coating formulation process and equipment technology and is expected to be put into mass production in the second half of this year.

At present, Shuopu New Materials has reached strategic cooperation with well-known automobile power lithium battery manufacturers such as Jiangxi Anchi, Jiangxi Funeng, and Tianjin lishen, and will also join hands with famous brands such as Shenzhen BYD, Fujian Ningde Times, and South Korea LG.
