The　specific　capacitance　of　redox　additive　based　electrolytes　in　supercapacitors　is　becoming　increasingly　important.　The　reduced　Graphene　Oxide　(rGO)-Dy2WO6-ZnO,　obtained　by　a　simple　hydrothermal　route　was　analyzed　by　high　resolution-transmission　electron　microscope　(TEM),　X-ray　diffraction　(XRD),　X-ray　photo-emission　spectroscopy　(XPS),　scanning　electron　microscope　(SEM),　BET　analysis,　and　cyclic　voltagram　(CV),　to　understand　its　structural　morphology,　chemical　constitution　and　electrochemical　efficiency　of　the　nanocomposite.　SEM　images　depict　porous　nanosheet　like　the　structure　of　rGO-Dy2WO6-ZnO　having　a　wave-type　pattern.　This　research　examines　the　capacitive　performance　of　rGO-Dy2WO6-ZnO　using　redox　additive　electrolyte　0.2　M　of　K-4[Fe(CN)(6)]　in　3　M　of　KOH.　The　composite　electrode　with　redox　additive　based　electrolyte　gives　synergistic　effects　and　enhances　the　capacitance　performance　up　to　752　Fg(-1)　at　the　current　density　of　1　Ag-1.　The　energy　storage　of　rGO-Dy2WO6-ZnO　electrode　material　in　0.2　M　of　K-4[Fe(CN)(6)]　in　3　M　of　KOH　is　greater　than　that　in　the　bare　aqueous　electrolyte　of　3　M　of　KOH.　Moreover,　the　rGO-Dy2WO6-ZnO　nanosheet　electrode　material　exhibits　excellent　cycling　stability　of　89.6%　up　to　2000　cycles.
