CuO and MoS2 difference including S -rGO and PPy nanocomposite for SupercapBattery device

Abstract

In this study, electrochemical performances of Copper (II) oxide (CuO) and Molybdenum (IV)sulfide (MoS2) were comparatively investigated by cyclic voltammetry (CV), galvanostatic chargedischarge (GCD) and electrochemical impedance spectroscopy (EIS) measurements. We have designedSupercapBattery with Al and Cu electrodes on 2032 coin cell. Ionic liquid (1-butyl-3-methylimidazoliumtetra fluoroborate) was used to carry out electrolyte between the anode and cathode compartments. Thehighest specific capacitance was obtained as Csp= 1110.32 F×g-1at 2 mV×s-1by CV method for SrGO/MoS2/PPy nanocomposite. CuO was seriously reduced the electrochemical performances ofSupercapBattery device (Csp= 113.10 F×g-1at 2 mV×s-1by CV method) for S-rGO/CuO/PPynanocomposite. (Electrode weights were obtained as 19.8 mg and 21.8 mg for S-rGO/MoS2/PPy and SrGO/CuO/PPy nanocomposites, respectively).
