Abstract:
A lithium ion battery separator consists of a PE micro-porous substrate A and a micro-porous coating B which is located on the substrate A and formed of mixing pre-crosslinked rubber particles and ceramic fine powder composite materials. The separator has characteristics of good compressible elasticity, thermal shutdown, low heat shrinkage, high temperature membrane rupture resistance and so on.
