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 charge discharge (GCD) and electrochemical impedance spectroscopy (EIS) measurements. We have designed SupercapBattery with Al and Cu electrodes on 2032 coin cell. Ionic liquid (1-butyl-3-methylimidazolium tetra fluoroborate) was used to carry out electrolyte between the anode and cathode compartments. The highest specific capacitance was obtained as Csp= 1110.32 F×g-1 at 2 mV×s-1 by CV method for SrGO/MoS2/PPy nanocomposite. CuO was seriously reduced the electrochemical performances of SupercapBattery device (Csp= 113.10 F×g-1 at 2 mV×s-1 by CV method) for S-rGO/CuO/PPy nanocomposite. (Electrode weights were obtained as 19.8 mg and 21.8 mg for S-rGO/MoS2/PPy and SrGO/CuO/PPy nanocomposites, respectively).
