This work reports a simple and robust approach to integrate MnOx nanoparticles onto flexible graphite paper using an ultrathin CNT/RGO supporting layer. Supercapacitor electrodes employing the MnOx/CNT/RGO nanohybrids without any conductive additives or binders yielded a high specific capacitance. The cycling stability of the nanohybrid electrodes was further improved through functionalizing the CNT/RGO supporting layer with atmospheric-pressure plasmas, demonstrating the synergistic use of nanohybrids and plasma-related effects for enhanced device performance.
