Abstract: The supercapacitor electrode material plays a decisive role on its performance. mon
electrode materials are carbon materials, metal oxide, conductive polymers. Graphene /MnOx
composite as materials for supercapacitors is a new research hotspot. The main business of graphene
and pound preparation methods (liquid phase coprecipitation method, in situ growth method,
electrochemical deposition), single electrode and used for asymmetric capacitor is analyzed. Brief
introduction of graphene with other posite, such as MnO, Mn3O4 is also introduced.
