Abstract
Effect of aqueous electrolytes (KOH, KCl, CH3 COONa and NH4 Cl) on electrochemical behaviour of Supercapacitor was studied by cyclic voltammetry, cyclic stability, and electrochemical impedance analysis. The results show that among all aqueous electrolytes investigated, KOH revealed good supercapacitive behaviour and exhibited 675Fgm-1 specific capacitance, 86% of cyclic stability, 100% columbic efficiency and 8Ω equivalent series resistance ESR.
