▎ 摘　　要

NOVELTY - Graphene composite flexible packaging film comprises first polymer layer, a first adhesive layer, a graphene film layer, a second adhesive layer, and a second polymer layer that are sequentially stacked. The bottom surface of the graphene film layer faces the first polymer layer. The layers are arranged and bonded to the first polymer layer through the first adhesive layer. The top surface of the graphene film layer is disposed opposite to the second polymer layer and is bonded to the second polymer layer through a second adhesive layer. USE - Graphene composite flexible packaging film used in lithium ion battery (claimed). ADVANTAGE - The graphene composite flexible packaging film exist very stably in the battery system and is resistant to electrolyte corrosion, and has excellent barrier properties and corrosion resistance, and improves battery life and safety performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a lithium ion battery, which comprises graphene composite flexible packaging film.
