NOVELTY - The capacitor (100) has an electrode cell (110) including cathodes (111) and anodes (112) alternately placed with separators (113) interposed. An electrolyte in a phase of gel is arranged on a surface of the anode. Another electrolyte in a phase of liquid is immerged into the electrode cell. The former electrolyte is selected from the group consisting of lithium phosphorus oxynitride (LiPON), A-site deficient perovskite-type oxide (L02/ 3-XLi3XTiO3), NASICON-type mixed phosphates (LiM2(P04)3) and lithium superionic conductor (lisicon) material(Li2+2Zn1GeO4).    USE - Lithium ion capacitor for preventing dendrite from growing from an anode and a liquid phase electrolyte for assisting using a gel phase electrolyte use in mobile information communication devices and electronic devices. Can also be used for an electric vehicles and mobile electronic devices.    ADVANTAGE - The capacitor provides a secure stability by preventing a dendrite from growing from an anode by forming an electrolyte in a phase of gel on a surface of the anode in an efficient manner. The capacitor reduces an energy density and weight by preventing the dendrite of the anode from growing, as the lithium metal can be used as the anode. The capacitor facilitates limitation of a high power density by including a liquid phase electrolyte for aiding the gel phase electrolyte in an efficient manner.    DETAILED DESCRIPTION - The latter electrolyte includes lithium salt and carbonate group solvent. The lithium salt includes Lithium Hexafluorophosphate (LiPF6), Lithium tetrafluoroborate (LiBF4) and Lithium perchlorate (LiClO4). The carbonate group solvent includes mixed solvent among propylene carbonate, ethylene carbonate, diethyl carbonate, dimethyl carbonate and ethyl methyl carbonate. The cathode active material layer is made of a charcoal.    DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of an electrode cell.
