The contrast tests of six electrodes: (a) Cyclic voltammograms at a scan rate of 20 mV s-1 in 1 M KOH aqueous electrolyte. (b) Galvanostatic charge-discharge at a current density 1 A g−1. Electrochemical performances of NiMn1.25OH@Ni3S2/NF: (c) Cyclic voltammograms at different scan rates in 1 M KOH aqueous electrolyte. (d) Galvanostatic charge-discharge at different current density (the inset shows the specific capacitance under different current densities).
