Reduced graphene oxides prepared via mass loading-controlled non-explosive thermal reduction for high volumetric capacitance supercapacitors

NE-TRGO was prepared by controlling the mass loading of the GO film. The NE-TRGO exhibits a high packing density of 1.94 g cm −3 . The volumetric specific capacitance of RGO-300-1.35 is 609 F cm −3 at 0.1 A g −1 .
