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

摘要

PROBLEM TO BE SOLVED: To provide a coating liquid having excellent electrolyte resistance and oxidation resistance, exhibiting high adhesion to a collector such as an aluminum foil or a copper foil, and capable of forming a conductive electrode film having a high surface resistance.

SOLUTION: The coating liquid used for forming a conductive coating film on the surface of a collector configuring the electrode plate for a power storage device contains (A) a polymer acid, (B) a native polyvinyl alcohol and/or a denatured polyvinyl alcohol having a saponification degree of 75 mol% or higher, (C) a conductive material, and (D) a polar solvent.
