Title:
The water surface-of-metal processing agent for lithium ion secondary batteries
Document Type and Number:
Japanese Patent JP5934695
Kind Code:
B2
Abstract:
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 using trivalent chromium. The aqueous metal surface treatment agent for a lithium ion secondary battery comprises a polyvinyl alcohol resin containing 2 to 15 mol% of a 1,2-diol structural unit represented by the formula (1):
having a degree of saponification of 90 to 99.9 mol% and an average degree of polymerization of 250 to 3000; and a metallic crosslinking agent.
