A novel supercapacitor material was synthesized from SiO₂-coated Co₃O₄ and CuO nanoparticles. These nanocapsules provided large specific surface area, fast electron transport, good mechanical stability and high electrochemical activity. The specific capacitance at 1 A g⁻¹ was 835.4 F g⁻¹, and it had excellent cycling performance.
