This study focuses on developing the anode material for hybrid supercapacitor applications. The widely used anode material or negative material for hybrid supercapacitors is activated carbon, Also, very few materials have been used for the alternate anodes, likely based on polyaniline and metal oxides. In this context, the transition metal oxide, like ZnO, is a well-known anode material in a potassium hydroxide electrolyte medium. Since the conductivity and electrochemical properties of ZnO are still limited, and to improve these properties, the Co3O4 material has been added to ZnO to prepare the composite, and the physical and electrochemical properties have been studied. The synthesized ZnO/Co3O4 composite exhibits better electrochemical properties than the bare ZnO.
