Document Type and Number:
Japanese Patent JP5848783
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide: a laminate superior in the adhesion between an electrode and a separator; a power storage device; and a lithium ion secondary battery.SOLUTION: A laminate according to the present invention comprises: at least one electrode; a separator base material; and a layer formed at least partially between the separator base material and the at least one electrode, and including a thermoplastic polymer. Further, in the laminate, the thermoplastic polymer includes a copolymer having, as monomer units, 2-66 mass% of an ethylenic unsaturated monomer having a chain alkyl group with 8 or more carbon atoms, and 34-98 mass% of other monomers copolymerizable with the ethylenic unsaturated monomer having a chain alkyl group with 8 or more carbon atoms.
