Ultrafine MnO nanowires grown on RGO-coated carbon cloth as a binder-free and flexible supercapacitor electrode with high performance.

Reduced graphene oxide coated carbon cloth has been used as a substrate for the growth of ultrafine MnO nanowires (CC/RGO/MnO), forming binder-free and flexible supercapacitor electrode materials. The experimental results indicate that a maximum area-specific capacitance of 506.8 mF cm was gained from the CC/RGO/MnO electrode at the current density of 0.
