Abstract

Abstract

Pseudocapacitive metal oxide active materials are promising for use in high performance supercapacitors. However, their poor electrical conductivity greatly hinders their practical application. We formed NiO and Co₃O₄ active materials on the surface of a highly conductive NiCo nanowire membrane current collector by a simple air oxidation method to fabricate a self-supported flexible NiO/Co₃O₄@NiCo electrode. This significantly improves electron transport at the interface between the current collector and the active NiO/Co₃O₄. Furthermore, the reticular nanowire network facilitates ion transportation and releases strain caused during charge and discharge. Due to this unique structural characteristic, the NiO/Co₃O₄@NiCo electrode delivers a high specific capacitance of 1.36 F cm^-2 at a current density of 5 mA cm^-2, and excellent cycling stability with a capacitance retention of 96.95% after 10 000 cycles. An asymmetric supercapacitor was assembled using the NiO/Co₃O₄@NiCo as the cathode and an activated carbon electrode as the anode, which delivered an energy density of 0.32 mWh cm^-2 at a power density of 8 mW cm^-2. Even at a high power density of 40 mW cm^-2, an energy density of 0.17 mWh cm^-2 was achieved, suggesting its promising use as an efficient electrode for high performance supercapacitors.
