Abstract

A battery separator composed of a microporous, composite sheet product having first and second major surface, formed from a uniform mixture of a polymer, a filler, a processing aid, a porous form stable layer at least partially embedded in either the first or second major surface. The weight ratio of polymer to filler is from about 1:4 to 1:50; preferably about 1:4 to 1:10.
