This is to provide an aqueous metal surface treatment agent for a lithium ion secondary battery which can improve interlaminar adhesiveness between a metal member and a resin coating layer such as a film or a coated film, and solvent resistance without usi...

A task of the present invention is to solve the problem in that the conductive undercoating agent composition for coating a current collector has so poor electrochemical durability that the conductive undercoating agent composition is peeled off the curren...

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...
