An AS-containing CNH and graphite ball was synthesized using a twin-torch-arc apparatus to make an electrode for an electrochemical capacitor with RuO2 of metallic catalyst. The electrode was composed of activated material, graphite, and binder. RuO2-AS was prepared by oxidization of Ru-AS. The capacitance current of RuO2-AS electrode increases with an increase in the catalyst loading amount. RuO2-AS electrode in case of 4 wt.% RuO2 has a capacitance current comparable to an AC electrode. The increase of specific capacitance for a composite electrode loading of 2 wt.% RuO2 was 360% (16.6–60 F/g), while that for a loading of 4 wt.% was 640% (16.6–106 F/g). RuO2-AS electrodes have a smaller internal resistance than not only AC but also AS. Capacitance current of RuO2-AS/AC electrode is about twice that of AC electrode and RuO2-AS electrode. The RuO2-AS/AC electrode has a high specific capacitance and smaller internal resistance than AC electrode and RuO2-AS electrode.
