Recently, Yangzi Petrochemical successfully produced the special resin for lithium ion battery separator, ultra-high molecular weight polyethylene. This is the first time that Sinopec has produced this product for the first time, breaking the monopoly of imported products for a long time and filling the domestic gap.

The diaphragm is one of the four materials of lithium-ion batteries, a key inner component. Limited by the technical level, the majority of the polyethylene raw materials currently used by the wet-membrane enterprises, which account for more than half of the domestic market share, can only rely on imports. The price of imported materials is as high as 20,000 yuan per ton, and the import volume is as high as 10,000 tons per year. Growing rapidly.

Aiming at this market opportunity, as early as 2014, Yangzi Petrochemical Research Institute began to develop special high molecular weight polyethylene resin for lithium ion battery separator. Last year, this project was officially established in the Ministry of Science and Technology of China. On May 27 this year, Yangzi Petrochemical first trial-produced this new product, and the output of more than 70 tons of products was analyzed and tested, and the performance was qualified, reaching the quality standard of imported products.
