MEMBRANOUS MEMBER FOR BATTERY AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a membranous member for a battery in a composite form with a functional membranous material and a gasket integrally formed, enabling to reduce the size and membrane thickness of the battery and to facilitate the assembly of the battery for productivity improvement. SOLUTION: A rubber layer for a gasket of a predetermined pattern is placed onto a functional membranous material for battery configuration in layers and in non-cross-linked condition, followed by a cross-link processing.
