The Li-ion battery separator is a microporous film with a main matrix of polyolefine film that has been manufactured using a one or two step stretching in hole crafts, and ion pass through functions. Li-ion batteries are known for the separate poles of positive and negative to avoid short circuiting. Following the development of separator technology, new types of li-ion battery separators have developed, including the PP/PE/PP compound separator, and ceramic coating separator. Each is characterized by the resistance to high temperatures, and the PVDF coating separator has one of the best performances on the market.
