Abstract

Microporous battery separators made of polyolefins and fillers, for lead/sulphuric acid accumulators, are characterized by the fact that the polyolefin component has an average molecular weight of over 5,000,000, and that the content of extractable oil in the finished separator is less than 1 %.
