▎ 摘  要

NOVELTY - Secondary battery pouch film comprises: a sealant layer (10); a first adhesive layer (401) formed on the sealant layer; a primer layer formed on the first adhesive layer; a core layer (20) formed on the primer layer; a second adhesive layer (402) formed on the core layer; and a surface layer (30) formed on the second adhesive layer, where at least one layer from the sealant layer, the primer layer, the first adhesive layer, the second adhesive layer and the surface layer includes graphene. The graphene is at least one of graphene, graphene oxide, reduced graphene oxide and graphene nanoplatelet. The core layer includes an aluminum foil or an aluminum deposition layer. USE - Secondary battery pouch film. ADVANTAGE - The pouch film: utilizes the graphene that increases a durability, and reduces gas permeability and moisture permeability; and exhibits excellent heat resistance, chemical resistance, and durability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for manufacturing the secondary battery pouch film. DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of a secondary battery pouch film. Sealant layer (10) Core layer (20) Surface layer (30) First adhesive layer (401 ) Second adhesive layer (402)
