【 摘 要 】

tsA facile strategy is proposed to construct novel CoO and NiO electrode material with interior (Cu+) and exterior (metallic Cu0) decoration for supercapacitor.The co-doped CoO electrode presents four times higher specific capacitance and more cycle stability than that of pristine CoO.The conductivity and electron transport rate of CoO with Cu0/Cu+ co-doping have been effectively improved and confirmed by detailed theoretical calculations.
