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 photoemission 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 K₄[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 K₄[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.

超级电容器中基于氧化还原添加剂的电解质的比电容变得越来越重要。通过高分辨率透射电子显微镜（TEM），X射线衍射（XRD），X射线光发射光谱（XPS）分析了通过简单水热途径获得的还原氧化石墨烯（rGO）-Dy ₂ WO ₆ -ZnO ，扫描电子显微镜（SEM），BET分析和循环伏安图（CV），以了解其结构形态，化学组成和纳米复合材料的电化学效率。SEM图像描绘了具有波型图案的类似于rGO-Dy ₂ WO ₆ -ZnO的结构的多孔纳米片。这项研究检查了rGO-Dy ₂ WO ₆的电容性能-氧化锌，在3 M的KOH中使用0.2 M的K ₄ [Fe（CN）₆ ]氧化还原添加剂电解质。与氧化还原添加剂基于电解质的复合电极给出了协同作用，并且提高了电容性能高达752蛋白原^-1 1 Ag的电流密度^-1。rGO-Dy ₂ WO ₆ -ZnO电极材料在3 M KOH中的0.2 M K ₄ [Fe（CN）₆ ]中的能量存储大于在3 M KOH中的裸露电解质中的能量存储。此外，rGO-Dy ₂ WO ₆ -ZnO纳米片电极材料在2000次循环之前表现出极好的循环稳定性，为89.6％。
