POSITIVE ELECTRODE FOR CAPACITOR AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a positive electrode having a practical thickness, a large capacitance, and a large output, and to provide a method for manufacturing the electrode. SOLUTION: The positive electrode for a capacitor is obtained by dispersing and molding a material having an oxide capable of occluding and discharging lithium and having conductive powder carrying the oxide thereon. The positive electrode has a thickness of 20μm or more. The oxide capable of occluding and discharging lithium is preferably a vanadium-based oxide, and the conductive powder is preferably carbon material powder of a specific surface area of 10 m2/g or more. The weight ratio of the oxide capable of occluding and discharging lithium to the conductive powder is preferably 7/3 to 1/9. COPYRIGHT: (C)2004,JPO&NCIPI
