More Information
Summary:A fabric separator woven from synthetic halogenated polymeric fibers for use in an electrochemical cell comprising a Group IA, IIA and IIIB metal anode and a depolarizer/catholyte or a solid cathode/electrolyte system, is described. The separator is resistant to the highly oxidizing components present in the cell, is tear resistant and has a reduced thickness to minimize the diminishing effect of the separator on the volumetric amount of active components in the cell. The separator can be used by itself or as a laminate with a microporous film, preferably made of a fluoropolymeric fiber.
