Aramid nanofibers/polyphenylene sulfide nonwoven composite separator fabricated through a facile papermaking method for lithium ion battery

Separator is a vital component in lithium ion battery (LIB) and its property is directly related to cell performance and safety. However, the current widely used polyolefin separator suffers from lower heat resistant and inferior electrolyte wettability. Therefore, more attention has been attracted in the development of high performance separator. In this study, aramid nanofibers (ANFs), poly(p-phenylene terephthalamide), and heat-resistant...
