Electrochemical performance of the solid-state MnO2/CNTs-25, MnO2/CNTs-40, MnO2/CNTs-60 and MnO2/CNTs-80 yarn electrodes. (a) CV curves of the MnO2/CNTs-25, MnO2/CNTs-40, MnO2/CNTs-60 and MnO2/CNTs-80 yarn electrodes measured at a scan rate of 10 mV/s. (b) GCD profiles of the MnO2/CNTs-25, MnO2/CNTs-40, MnO2/CNTs-60 and MnO2/CNTs-80 yarn electrodes measured at 1 mA/cm2 (c) areal specific capacitance measured of each electrode at different current densities in the potential range of 0–1 V. (d) Capacitive and diffusive capacitance contribution at a scan rate of 5 mV/s.
