▎ 摘　　要

NOVELTY - The positive electrode busbar structure capable of generating graphene by friction comprises a multiple of positive electrode current collectors. The positive electrode tab is provided on one side of each positive electrode current collector. The disk is provided on the positive pole ear and is suitable for friction with the positive pole ear to generate graphene. The cathode current collector and the cathode bus plate are formed of graphite. The cathode current collector is graphite foil. The positive electrode busbar is a graphite plate. USE - Positive electrode busbar structure capable of generating graphene by friction. ADVANTAGE - Positive electrode busbar structure is effectively reduced the internal resistance of the contact surface, and increased the electron transmission path. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing positive electrode collector involves providing a graphite foil, using graphite plate to the surface of the graphite foil to friction. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the positive electrode bus structure of the graphene.
