Title:
BATTERY PACKAGING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2024/024713
Kind Code:
A1
Abstract:
The present invention improves adhesive strength at high temperatures in a battery packaging material in which an active energy-curable adhesive is used. This battery packaging material 1 comprises a barrier layer 11 that has one surface that is bonded to a heat-resistant resin layer 13 with a first adhesive layer 12 interposed therebetween, and another surface that is bonded to a sealant layer 15 with a second adhesive layer 14 interposed therebetween. The first adhesive layer 12 is constituted by an adhesive composition that includes polyester polyurethane acrylate (A) and a (meth)acrylate monomer (B) that has an isobornyl group, in a mass ratio of (A)/(B) = 1/1–8/1.
