Recently, Yangzi Petrochemical successfully produced ultra-high molecular weight polyethylene
, a special resin for lithium-ion battery separators, for the first time.
It is reported that this is the first time in China and the first time Sinopec has produced this product, breaking the monopoly of imported products for a long time and filling the domestic gap
.
The separator is one of the four major materials of lithium-ion batteries, a key inner component
.
Limited by the level of technology, most of the polyethylene raw materials currently used by wet diaphragm enterprises accounting for more than half of the domestic market share can only rely on imports, and 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, and it is still growing
rapidly.
As early as 2014, Yangtze Petrochemical Research Institute began to develop special resins
for ultra-high molecular weight polyethylene for lithium-ion battery separators.
Last year, the project was officially approved by the Ministry of Science and Technology of Sinopec
.
On May 27 this year, Yangzi Petrochemical trial-produced this new product for the first time, and the output of more than 70 tons of products was analyzed and tested, and the performance was qualified, reaching the quality standards
of imported products.
