Figure 6

(a) SEM image of MnOx nanoparticles electrodeposited on a plasma-treated CNT/RGO surface. The inset is a photo of CNT/RGO surfaces that shows the wettability change before and after plasma treatment. (b) Cyclic voltammetry (CV) curves of MnOx/CNT/RGO nanohybrid with plasma treatment at scan rates of 10, 20 and 50 mV s−1. (c) Charge/discharge curves of MnOx/CNT/RGO nanohybrid with plasma treatment at current densities of 5, 10 and 20 A g−1. (d) The capacitance retention of MnOx/CNT/RGO nanohybrid with plasma treatment is 87% after 1000 cycles at 100 mV s−1.
