Abstract:

This paper reviewed the performance requirements of lithium⁃ion battery separators and the development status of heat⁃resistant polymer separators at home and abroad. The polymer separators based on polyetheretherketone, polyethylene terephthalate, polyvinylidene fluoride, and polyimide were mainly discussed. The characteristics, preparation methods, and properties of various polymer separators were introduced, and the future development direction of polymer separators was prospected.

Key words: lithium?ion battery, separator, polymer, heat temperature resistant, safety
