NOVELTY - A one graphene-base polymer lithium cell cathode structure, comprising: a negative electrode electrolyte layer graphite, graphene film layer, copper foil. Polymer lithium power of negative current collector copper foil on growing graphene thin film layer, graphene film layer attached to the graphite electrolyte layer. The graphene thin film layer as cathode graphite electrolyte layer and current collector of copper foil between the conducting layer, add have conducting layer and electric conduction capacity, increase have energy density of lithium battery, and the graphene thin film layer and graphite and copper foil are the chemistry key firmly combined, reducing the contact resistance and have heat resistance, graphene film layer between graphite and copper foil is set with the good heat conducting performance, and the cathode can generate the heat derive, reducing have the temperature change caused by the negative electrode material, add have circulation use life of polymer lithium power.
