Two-step synthesis of MnCo2S4 nanowires for supercapacitor electrode

In this study, MnCo2S4 nanowires were synthesized on 3D-Ni foam by the hydrothermal process in two-step and investigated as supercapacitor electrode material. Crystal structure and morphology analyzes of MnCo2S4 nanowires were performed. Electrochemical measurements were taken in 1 M of a potassium hydroxide aqueous electrolyte solution. The specific capacitance value calculated from GCD measurement taken at a current density of 0.5 A g−1 from the sample was 450 F g−1 . Furthermore, the sample have good cycling stability by keeping 46% of the initial specific capacitance after 3000 cycles.
