Effect of Mn:(CuO/Cu(OH)2) Electrodes for Supercapacitors Application

In the present study, we report structural and electrochemical properties of Mn:(CuO/Cu(OH) 2 ) electrodes were investigable made-up on stainless steel via surfactant-free and inexpensive successive ionic layer adsorption and reaction (SILAR) method. Further, these CuO(CuOH) 2 and 3% Mn:CuO(CuOH) 2 electrodes exhibits outstanding surface properties like uniform growth on surface, high surface area and uniform pore size distribution of pure and doped CuO samples. The electrochemical properties of pure and 3% Mn doped (CuO(CuOH) 2 ) nanostructure have been investigated by cyclic voltammetry, charge discharge. The electrochemical studies of the pure and 3% Mn doped (CuO(CuOH) 2 ) samples show evident influence of surface properties on the pseudo capacitance performance. The maximum specific capacitances of nanoflowers like CuO electrodes are found to be 597 Fg −1 , respectively at 5 mV s −1 scan rate. Present investigation suggests the inexpensive SILAR move toward for fine modification surface properties of 3% Mn:(CuO(CuOH) 2 ) materials for energy storage applications. © 2015 American Scientific Publishers.
