Figure 5. Electrochemical performances of CAC and CAC-x electrodes in a three-electrode system using 6M KOH as electrolyte. (A) CV curves at 10 mV s^-1 and (B) GC curves at 0.5 A g^-1 of CAC and CAC-x. (C) CV curves of CAC-24 at various scan rates from 10 mV s^-1 to 1,000 mV s^-1. (D) Gravimetric capacitances of CAC-x calculated from GC curves. (E) Volumetric capacitances of CAC-x based on material skeleton densities. (F) Comparison of the volumetric and gravimetric capacitances of CAC-24 electrode with other reported carbon electrodes.
