Galvanostatic charge/discharge (GCD) profiles at rates between 20 -5,000 mA/g are shown in Fig. . The potential profiles at low rates are comparable for all samples, with variations in the maximum capacity. The samples show cathodic (lithiation) capacities at a rate of 20 mA/g with 169 mAh/g (V2O5-2C-DA), 193 mAh/g (V2O5-6C-DA) and 155 mAh/g (V2O5-12C-DA). However, at higher rates like 5 A/g, a reduced polarization is observed for V2O5-12C-DA compared to V2O5-2C-DA and V2O5-6C-DA, indicating improved kinetics for the V2O5 host with the largest interlayer spacing.
