MnO2/reduced graphene oxide composite as high-performance electrode for flexible supercapacitors

In this paper, we reported a facile method to prepare MnO2/reduced graphene oxide (RGO) composites and examined their applications as electrodes in flexible solid-state supercapacitors. The as-fabricated solid-state device based on these MnO2/RGO composite electrodes exhibit a good electrochemical performance with an area capacitance of 14 F cm− 2 at 2 mV s− 1 and excellent stability.
