POSITIVE ELECTRODE FOR ELECTRIC DOUBLE-LAYER CAPACITOR USING GRAPHITE AND ELECTRIC DOUBLE-LAYER CAPACITOR

摘要

PROBLEM TO BE SOLVED: To provide an electric double layer capacitor which has large electrostatic capacitance. SOLUTION: Graphite with a BET surface area of 10 to 300 m2/g, has an energy storing ability of 10 to 200 mAh at a voltage of 1 V or more, based on the oxidation-reduction potential of lithium. A charge storage element uses the graphite. COPYRIGHT: (C)2008,JPO&INPIT
