摘要：
High-performance supercapacitor electrodes with a core-shell heterostructure of carbon-fabric/NiCo2S4/Ni(OH)(2) are rationally designed. The NiCO2S4 nanotube core synthesized by two step hydrothermal methods has a diameter of about 120 nm and a thickness of about 25 nm. The Ni(OH)(2) shell prepared by electrochemical deposition method is made up by the small Ni(OH)(2) ultrathin sheets. With this design and method, high specific capacitance of 2700 F/g at a current density of 1 mA/cm(2) is found from NiCO2S4/Ni(OH)(2) heterostructured arrays. These samples show energy density of 120 Wh/kg and power density of 0.4 kW/kg at a current density of 1 mA/cm(2), and good cycle stability with 78% capacitance retention after 2000 circles.
