NOVELTY - The utility model claims a lithium ion battery with high capacity of graphene, comprising a wound-type electrode group and a battery shell, an electrode group housed in the battery shell; the anode of the electrode group is provided with a lithium ion supply unit; This utility model lithium battery through the anode foil is equipped with a layer of graphene, increase the conductivity of anode foil on the anode foil is high non-charging potential of the positive electrode of the same with the ions in the electrolyte of the lithium ion supply unit when it is not charging covering part has blocking action of the film. to prevent reaction between metal lithium and a positive electrode, the positive electrode will not over-discharge, the potential reaches the potential redox reaction is, covering part to dissolve the lithium ion supply unit exposed to the electrolyte and react with the anode to prevent deterioration of battery capacity.
