Document Type and Number:
Japanese Patent JP7381528
Kind Code:
B2
Abstract:
Provided is an outer material for power storage devices. According to the present invention, the outer material comprises: a heat-resistant resin layer (2) as an outer layer; a sealant layer (3) as an inner layer; and a metal foil layer (4) disposed between both layers. At least the innermost layer (7) of the sealant layer (3) contains an elastomeric-modified olefin-based resin. The elastomer-modified olefin-based resin is composed of an olefin-based thermoplastic elastomer-modified homopolypropylene or/and an olefin-based thermoplastic elastomer-modified random copolymer. The olefin-based thermoplastic elastomer-modified random copolymer is an olefin-based thermoplastic elastomer modified product of a random copolymer containing propylene and other copolymerization components except for propylene as a copolymerization component. Accordingly, satisfactory sealing properties of the sealant layer of the outer material can be maintained even when exposed to a high-temperature environment for a long period.
