Abstract

A FLEXIBLE POLYMERIC FILM IN USEFUL AS AN INTERELECTRODE SEPARATOR OR ELECTROLYTE MEMBER IN ELECTROLYTIC DEVICES, SUCH AS RECHARGEABLE BATTERIES, COMPRISES A COPOLYMER OF VINYLIDENE FLUORIDE WITH 8 TO 25% HEXAFLUOROPROPYLENE.THE FILM MAY BE CAST OR FORMED AS A SELF-SUPPORTING LAYER RETAINING ABOUT 20% TO 70% OF A HIGH-BOILING SOLVENT OR SOLVENT MIXTURE COMPRISING SUCH AS ETHYLENE CARBONATE, PROPYLENE CARBONATE, DIMETHYL CARBONATE, AND DIBUTYL PHTHALATE. THE FILM MAY BE USED IN SUCH FORM OR AFTER LEACHING OF THE RETAINED SOLVENT WITH A FILM-INERT LOW-BOILING SOLVENT TO PROVIDE A SEPARATOR MEMBER INTO WHICH A SOLUTION OF ELECTROLYTIC IS SUBSEQUENTY IMBIBED TO DISPLACE RETAINED SOLVENT OR REPLACE SOLVENT PREVIOUSLY LEACHED FROM THE POLYMERIC MATRIX.
