Abstract
- Ultra-thin and porous MgCo2O4 nanowires with larger specific surface area was successfully synthesized on Ni foam by hydrothermal method with surfactant sodium dodecylsulphate. It showed that MgCo2O4 nanowires exhibited a dense interwoven and transparent net-like structure with a high specific capacitance of 2128 F/g at a current of 5 A/g. After 6000 cycles under the condition of 40 A/g, 98.4% of initial capacitance was retained. Additionally, asymmetric supercapacitor was assembled with this nanowires as binder-free positive electrode and activated carbon as negative electrode respectively, which displayed a specific capacitance of 65.32 F/g and energy density of 20.41 Wh/kg under the power density of 338.95 W/kg. The above results show that the asymmetric supercapacitor is a good energy storage device which has good potential in practical applications. [ABSTRACT FROM AUTHOR]
