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

Abstract

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.
