Interior and Exterior Decoration of Transition Metal Oxide Through Cu⁰/Cu⁺ Co-Doping Strategy for High-Performance Supercapacitor.

ABSTRACT: Although CoO is a promising electrode material for supercapacitors due to its high theoretical capacitance, the practical applications still suffering from inferior electrochemical activity owing to its low electrical conductivity, poor structural stability and inefficient nanostructure. Herein, we report a novel Cu⁰/Cu⁺ co-doped CoO composite with adjustable metallic Cu⁰ and ion Cu⁺ via a facile strategy. Through interior (Cu⁺) and exterior (Cu⁰) decoration of CoO, the electrochemical performance of CoO electrode has been significantly improved due to both the beneficial flower-like nanostructure and the synergetic effect of Cu⁰/Cu⁺ co-doping, which results in a significantly enhanced specific capacita
