Figure 6From: Hydrothermal synthesis of MnO2/CNT nanocomposite with a CNT core/porous MnO2 sheath hierarchy architecture for supercapacitorsCyclic 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.Back to article page
