Aluminum-plastic packaging films and lithium ion batteries using them

摘要

The present invention provides an aluminum-plastic packaging film and a lithium ion battery using the same, wherein the aluminum-plastic packaging film (1) comprises an aluminum layer (12), a graphene layer (14) and a sealing layer , The graphene layer 14 comprises a graphene sheet and a thermoplastic polymer adhesive. Since the graphene has a layered structure, a curved and complicated path is formed at a position where the sheet and the sheet of irregularly arranged grains intersect with each other, and thus, the lithium ions are subjected to a great effect in the process of moving to the aluminum layer, It is possible to prevent the lithium ion and the aluminum metal from forming the aluminum-lithium alloy, and to avoid the corrosion of the aluminum layer 12.
