▎ 摘　　要

NOVELTY - A graphene-silver composite tab comprises a polar ear matrix, a graphene layer formed on a part of a surface of the polar ear substrate and a silver layer, which is formed on a part of the surface of the graphene layer away from the pole base. USE - Graphene-silver composite tab for a lithium battery pole piece (claimed). ADVANTAGE - The composite tab improves the electrical and thermal conductivity of the tabs and reduces the internal resistance and temperature rise of the pole pieces. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing graphene-silver composite tab, which involves providing a polar ear base, forming a graphene layer on a part of the surface of the pole base and a silver layer on a part of the surface of the graphene layer away from the pole base.
