GRAPHENE LITHIUM ION CAPACITOR

The present invention proposes a graphene lithium ion capacitor formed of a graphene material and including electrodes pre-doped with lithium ions. There is provided a graphene lithium ion capacitor according to an exemplary embodiment of the present invention, including: at least a part of a cathode and an anode formed of a graphene material; a lithium sacrificial electrode electrically connected to the anode so as to provide pre-doping lithium ions to the anode; a separator disposed between the cathode and the anode; and an electrolyte bonded to the cathode and the anode in a state of being dissociated into ions to flow current between the cathode and the anode, in which the anode is formed of a multilayered structure so as to adsorb lithium ions provided from the lithium sacrificial electrode on the surface and accommodate the lithium ions intercalated between graphene layers, and at least a part of the surface and the multilayered structure are formed of lithium carbide by reaction with the lithium ions.
