چکیده

Supercapacitors represent a new class of energy storage devices that have been attracted many researchers in last few years. Graphene with unique properties such as superior electrical conductivity and large specific surface area is one of the most suitable materials in supercapacitor applications. Therefore graphene, especially chemically modified graphene is one of the most promising carbon materials to be applied to energy storage systems. Besides, metal oxides are being used as active compounds in supercapacitors due to their role in redox reactions. In this research, sonochemical synthesis and characterization of a novel manganese oxide (MnO2)/reduced graphene oxide (RGO) nanohybrid that coated onto stainless steel (SS) was studied. The electrochemical performance of the MnO2/SS and MnO2/RGO/SS electrodes were compared by electrochemical methods.
