AQUEOUS PASTE FOR ELECTROCHEMICAL CELL, ELECTRODE PLATE FOR ELECTROCHEMICAL CELL OBTAINED BY APPLICATION OF THE AQUEOUS PASTE, AND BATTERY COMPRISING THE ELECTRODE PLATE

摘要

Disclosed is an aqueous paste that contains: an aqueous dispersion for an electrochemical cell, which contains an olefin copolymer (a); an active material; and a conductive assistant. The olefin copolymer (a) is composed of at least one copolymer that is selected from among random propylene copolymers (a-1) that have a weight average molecular weight of not less than 50,000 and contain a constituent unit derived from propylene in an amount of 50% by weight or more but less than 85% by weight, acid-modified random propylene copolymers (a-2) that are obtained by modifying the copolymers (a-1) with an acid, and ethylene-(meth)acrylate copolymers (a-3) that contain a constituent unit derived from a (meth)acrylic acid in an amount of 5% by weight or more but less than 25% by weight.
