These are considered important energy efficiency devices for rapid energy storage and delivery. Among the advantages of ESs are high power density, environmentally friendly, long cycle life, high efficiency, wide range of operating temperatures, environmental friendliness and safety . ESs also serves as a bridging function for the power/energy gap of traditional dielectric capacitors. These characteristics have made ESs very competitive for applications in electric hybri d vehicles, digital communication devices such as ABSTRACT Manganese doped Cobalt oxide thin films were deposi ted on steel substrate by sol-gel spin coat method and investigated the impact of doping on electrochemica l behaviour. Cyclic Voltammetry technique was used for the electrochemical characterizations of supercapacitor ells fabricated usin...
