Document Type and Number:
WIPO Patent Application WO/2019/017457
Kind Code:
A1
Abstract:
Provided is a battery wrapping material in which a barrier layer comprising an acid-resistant film has excellent long-term adhesion. This battery wrapping material is formed from a layered body comprising at least a substrate layer, a barrier layer and a thermally adhesive resin layer in that order, and comprises an acid-resistant film on the surface of at least one side of the barrier layer. When the acid-resistant film is analysed using time-of-flight secondary ion mass spectrometry, the ratio PPO3/CrPO4 of the peak intensity PPO3 derived from PO3
- to the peak intensity PCrPO4 derived from CrPO4
- is in the range of 6-120.
