Using a scaleable chemical method, the ultrathin MnO2 nanosheets-decorated CuO nanoneedle arrays@Cu sheet has been synthesized and applied as electrodes, while CuO nanoneedles were obtained via an electrochemical deposition at room temperature. Such binder-free Cu/CuO@MnO2 electrodes were measured by using X-ray diffraction (XRD), and field emission scanning electron microscopy (FESEM) to investigate the structure and morphology. Further electrochemical characterizations revealed that the specific capacitance of samples prepared in 24-hour reaction was as high as 177 mF cm -2 at current density 0.5 mA cm -2 , with a stable cycling performance of 87.3% retention after 1000 cycles. These findings suggest that the Cu/CuO@MnO2 electrode is a promising candidate for excellent electrochemical capacitors.
