Comparative Study of Mno2 and Polypyrrole for Supercapacitor Application

Abstract

This paper is related to comparative study of Mno2 and polypyrrole, Mno2 and polypyrrole are separately deposited on two different stainless steel substrate using electrodeposition method, we have studied their super capacitance behaviour using cyclic voltammetry technique and charge discharging curve. We got maximum capacitance value equal to 184.42 F/gm and 29.72 F/gm For MnO2 and Polypyrrole so Mno2 shows better performance than polypyrrole.
