Title:
LITHIUM ION SECONDARY BATTERY EXTERIOR PACKAGING MATERIAL
Document Type and Number:
Japanese Patent JP2018060765
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a lithium ion secondary battery exterior packaging material which never causes whitening or degradation therein even when an electrolyte solution deposits on an outer side of an exterior packaging material for a long time, or when the electrolyte solution of a high temperature deposit thereon, which never causes whitening or degradation therein even when used in a high-temperature and high-humidity atmosphere, and which never causes whitening or degradation even when the electrolyte solution deposits on an edge portion formed in processing the exterior packaging material.SOLUTION: A lithium ion secondary battery exterior packaging material comprises at least, a protection layer, a polyamide resin layer, an aluminum foil layer and a sealant layer which are laminated in this order. The protection layer includes 100 pts.mass of an acid-modified polyolefin resin, 5-1000 pts.mass of polyvinyl alcohol, and 0.1-50 pts.mass of a crosslinking agent.SELECTED DRAWING: None
