(a) CVs of the SnO2@NGO composite electrodes at various scan rates of (10–100) mV s−1 in 6 M KOH. (b) Charge/discharge profiles of the composite electrode at different current densities (4, 8.5, and 12.6) A/g. (c) Variation of specific capacitance as a function of cyclic number at a current density of 4.0 A/g, (d) EIS, and (e) the effect of Energy density vs. Power density.
