        abstract = {Supercapacitors are an emerging class of energy storage devices combining high power density, long cycle life, and rapid charge–discharge rates. Electrode material selection critically commands their efficiency. Efficiency of supercapacitor is multifaceted, depending on a material’s capacitance, energy density, power density, rate capability, electrical conductivity, cyclability, and manufacturing feasibility Current research has explored the sustainable synthesis of Metal oxides emerged as promising materials for supercapacitor electrodes owing to their high theoretical capacitance, multiple oxidation states, and better chemical stability than polymers. This review confers information about supercapacitor’s performance formed by metal oxides. Detailed about preparation methods and supercapacitor properties are discussed.},
