Fig. 5. CV curves of the (a) CPC10 and (b) CPR10 electrodes at different scan rates. (c) Maximum current vs. scan rate of two electrodes determined from their corresponding CV curves. GCD curves for the (d) CPC10 and (e) CPR10 electrodes at different current densities. (f) Nyquist plots of the two electrodes. (g) Areal capacitances of the two electrodes at different scan rates. (h) Gravimetric capacitances of the two electrodes at different current densities. All data were obtained under three-electrode testing conditions in 1 M H2SO4.
