▎ 摘　　要

NOVELTY - Lithium ion battery current collector comprises a conductive carbon layer attached to one surface of an organic substrate layer. The organic substrate layer is a porous membrane. The conductive carbon layer comprises superconducting carbon black, acetylene black, ketjen black, Super P (Conductive carbon black), Super S (Conductive carbon black), carbon nano tube, graphene, porous carbon and/or carbon fiber. USE - Used as lithium ion battery current collector. ADVANTAGE - The lithium-ion battery current collector has the function of confluence and can also isolate the isolating film effect of the anode and cathode and belonging to the double-function current collector. The lithium ion battery has good electrical conductivity, high mechanical strength, strong manufacturing process compatibility and reduced weight. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing lithium-ion battery current collector; (2) a anode or cathode sheet; (3) preparing anode or cathode sheet; and (4) a lithium-ion battery.
