Electrochemical behaviours of PPy-MnO2-CFs SCs with different growth conditions of their electrode materials.
(a and b) CV curves of the SCs with MnO2 electrodeposition time from 1 to 45 min; (c) specific capacitances vs MnO2 electrodeposition time; (d and e) CV curves of the SCs with PPy electrodeposition time from 0.5 to 3 min; (f) specific capacitances vs PPy electrodeposition time.The scan rate of all the CV curves was 10 mV s−1.
