The high temperature resistant high porosity lithium ion battery separator is a new type of lithium ion battery separator with special non-woven fabric as the base material. The product has a three-dimensional network structure, which breaks through the traditional technical scheme of the material composition of the polyolefin microporous diaphragm and has high temperature resistance. High porosity, excellent electrolyte wetting, high liquid absorption and liquid retention, and excellent puncture resistance. The lithium ion power battery assembled with it has outstanding performance in terms of cycle life, safety and capacity. Mainly used in automotive power lithium-ion batteries and high-safety energy storage lithium-ion batteries.
