▎ 摘　　要

NOVELTY - A graphene lithium-ion capacitor (100) consists of cathode (120, 160) and anode (110, 150) having at least a portion formed using graphene material, sacrificial lithium electrode (130) which is electrically connected to the anode such that pre-doping lithium ions are supplied to the anode, a membrane (140) which is disposed between the cathode and the anode, and an electrolyte. The graphene lithium-ion capacitor is formed in a multilayered structure in order to accommodate the lithium ions (131) which are interposed between the layers of graphene (111, 121), on the surface of anode. USE - Graphene lithium-ion capacitor (claimed). ADVANTAGE - The graphene lithium-ion capacitor has excellent output characteristics and high energy density. The graphene contained in the capacitor has excellent conductivity and large specific surface area of 2675 m2/g. DETAILED DESCRIPTION - A graphene lithium-ion capacitor (100) consists of cathode (120, 160) and anode (110, 150) having at least a portion formed using graphene material, a sacrificial lithium electrode (130) which is electrically connected to the anode such that pre-doping lithium ions are supplied to the anode, a membrane (140) which is disposed between the cathode and the anode, and an electrolyte. The graphene lithium-ion capacitor is formed in a multilayered structure in order to accommodate the lithium ions (131) which are interposed between the layers of graphene (111, 121), on the surface of anode. The multi-layered structure is formed using lithium carbide by reaction with the lithium ions. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of graphene lithium ion capacitor.
