(a) Cyclic voltammetry curves of V20-rGO, activated reduced graphene oxide (ArGO), and thermally treated ArGO (TArGO) at a scanning rate of 2 mV/s. (b) Cyclic voltammetry curves of TArGO depending on the potential sweep rates. (c) Galvanostatic charge/discharge curves of V20-rGO, ArGO, and TArGO under a constant current density of 1 A/g. (d) Galvanostatic charge/discharge curve of TArGO depending on the constant current densities. (e) Specific capacitances of V20-rGO, ArGO, and TArGO as functions of constant current density. (f) Specific capacity vs cycle number of TArGO at a constant current density of 10 A/g.
