(a) CV curves of composites KCP-700, KCP-800, and KCP-900 electrodes and single-silk carbon KSW-800 electrode at 10 mV/s. (b) Nyquist plots for those electrodes measured at 0 V DC potential in the frequency range of 100 kHz to 10 MHz. (c) Specific capacitance of the four samples at different current densities in 6 M KOH electrolyte.
