Figure 7: Electrochemical performance of reassembled δ-MnO2 electrodes.
From: The critical role of point defects in improving the specific capacitance of δ-MnO2 nanosheets
Electrochemical testing results: (a) CV curves for the samples at 50 mV s−1 scan rate; (b), (c) and (d) galvanostatic charge–discharge curves of the pH=2, 4 and HxMnO2 samples; (e) comparison of specific capacitance for the samples as a function of current density; and (f) cycle stability at constant current density of 5 A g−1 between 0 and 1 V.
