Abstract
An aluminum laminated packaging film, and lithium-ion battery using same. The aluminum laminated film (1) comprises an aluminum layer (12), a graphene layer (14), and a sealing layer (13) in sequence. The graphene layer (14) comprises graphene sheets and a thermoplastic polymer adhesive. The platelet structure of the graphene and irregular arrangement of the graphene enable locations between sheets to form indirect and complex paths, creating a huge barrier for lithium ions moving toward the aluminum layer, thus preventing the lithium ions from forming aluminum-lithium alloy with the metal aluminum, and avoiding corrosion of the aluminum layer (12).
