Abstract

In this work, a novel hierarchical CuCo₂O₄@MnO₂ composite with core-shell structure grown on RGO (coated on the surface of nickel foam (NF)) was synthesized via a facile hydrothermal route, in which MnO₂ nanosheets uniformly wrapped around the surface of CuCo₂O₄ nanorods. RGO/CuCo₂O₄ composite was also prepared for comparison. Benefiting from their synergistic effect, RGO/CuCo₂O₄@MnO₂ electrode delivered high specific capacitance of 850 F g⁻¹ at 1 A g⁻¹ in 2.0 M KOH electrolyte and an outstanding cycling stability with 94.2% retention over 3000 cycles, suggesting the great potential application of this material in advanced energy storage device.
