Fig. 8. (a) Ragone plots of power density vs. energy density for the two assembled supercapacitors. (b) Cycling stabilities of the two assembled supercapacitors. CV curves of (c) CPC10 and (d) CPR10 electrodes at different bending angles. Representative photographs of (e) CPC10 and (f) CPR10 electrodes in normal and bent states. CV curves of (g) CPC10 and (h) CPR10 electrodes after folding 200 times at a scan rate of 50 mV s−1. (i) Stability of electrode capacitance after 200 bending cycles according to CV curves in (g) and (h). Illustration is the schematic diagram of the electrode's bending state. All data were obtained under two-electrode testing conditions with PVA/H3PO4 gel electrolyte.
