PURPOSE: A lithium ion capacitor is provided to obtain a coin type stability by a self-discharge process and a cell activation process. CONSTITUTION: A lithium ion capacitor includes an organic solvent electrolyte. An anode(240) includes an active carbon based anodic active material. A first separation layer(250) is interposed between a graphite electrode(262) and the anode. The graphite electrode includes a first current collector and a cathode active material. The cathode active material is coated on the first current collector. A lithium metal member(266) faces the graphite electrode. The lithium metal member is connected to the graphite electrode. The lithium metal member and the graphite electrode function as one cathode(260).
