Fig. 5 (a) Comparison of the CV curves of NiCo2S4, P–NiCo2S4, NiCo2S4−x, and P–NiCo2S4−x at a scan rate of 10 mV s−1. (b) CV curves of P–NiCo2S4−x at different scan rates. (c) Determination of the b-values of NiCo2S4, P–NiCo2S4, NiCo2S4−x and P–NiCo2S4−x from the current densities of cathodic peaks using the power law. (d) Histogram illustrating the ratio of capacitive and diffusive contributions to capacitance at 10 mV s−1. (e) Comparison of the GCD curves of NiCo2S4, P–NiCo2S4, NiCo2S4−x, and P–NiCo2S4−x at a current density of 1 A g−1. (f) GCD curves of P–NiCo2S4−x obtained at different current densities. (g) Specific capacities obtained at various current densities. (h) Cycling performances of NiCo2S4, P–NiCo2S4, NiCo2S4−x and P–NiCo2S4−x at a high current density of 30 A g−1. (i) Schematic illustrating the structural advantages of P–NiCo2S4−x nanotubes in terms of electrochemical reactivity.
