Nano-Metal Oxide Based Supercapacitor Via Electrochemical Deposition

Abstract

In this rapid growing world, the demand of alternate or non-conventional energy sources with high density and power has been tremendously increased. Supercapacitor is one of the promising energy storage devices which possess high specific capacitance, high power density and long life cycle. The performance of supercapacitors is evaluated by its electrode materials. Among the various supercapacitor electrode materials, recent research focused on synthesis of transition metal oxides/ hydroxides, carbon metals and polymers. Transition metal oxides such as manganese oxide (MnO ), ruthenium oxide (RuO ), cobalt oxide (Co O ), nickel oxides (NiO) etc. have been widely used as supercapacitor 2 2 3 4
