ABSTRACT:
A battery separator, and a method of forming the same, which exhibits good electrical conductivity and a high degree of inhibition to dendrite formation, is in the form of a thin sheet formed from a substantially uniform mixture of a thermoplastic rubber and a filler in a volume ratio of from about 1:0.15 to 1:0.6. The thermoplastic rubber is preferably a styrene/elastomer/styrene block copolymer.
