COATING LIQUID, CONDUCTIVE COATING FILM, ELECTRODE PLATE FOR ELECTRICITY STORAGE DEVICE, AND ELECTRICITY STORAGE DEVICE

摘要

Disclosed is a coating formulation useful in forming a conductive coating film on a surface of a collector for constructing an electrode plate for an electricity storage device. The coating formulation contains (A) a polymeric acid, (B) a vinyl carboxylate copolymer represented by the following formula (1):
wherein R 1 is selected from the group consisting of H, Na, organic groups derived from vinyl carboxylate monomers, and cations capable of forming electrolytes for the electricity storage device, R 2 to R 4 are independently selected from the group consisting of H, Na, C 1 -C 6 alkyl groups, and cations capable of forming electrolytes for the electricity storage device, and a ratio (m/n) of m to n is from 0.0001 to 1, (C) a conductive material, and (D) a polar solvent.
