Cyclic voltammograms and specific capacitance vs. scan rate of the different electrodes. Cyclic voltammograms for the (a) CNT, (b) pure MnO2, and (c) MnO2/CNT nanocomposite electrodes in a 1-M Na2SO4 solution at different scan rates from 10 to 100 mV/s. (d) Specific capacitance vs. scan rate of the different electrodes.
