Abstract

The characteristics of microporous separator for lithium ion secondary battery was introduced. Microporous separator is a key component of a lithium ion secondary battery because its basic properties were related with the performance and safety of the battery. Up to now, stretched microporous polyolefins such as polyethylene(PE) separator were mainly applied. It is still required to enhance wettability and shut-down property. For this purpose, the application of fluorovinylic polymers and surface modification of conventional polyolefinic microporous membrans we being continuously tried.
