Abstract

In this study, 3 different materials were combined to form hybrid nanocomposite forSupercapBattery applications. The effects of using sulfur (S) doped and undoped reduced graphene oxide(S-rGO), Molybdenum (IV) sulfide (MoS2), and polyaniline (PANI) were used as a component ofnanocomposites. Electrochemical performances were performed by cyclic voltammetry (CV),galvanostatic charge / discharge (GCD) and electrochemical impedance spectroscopy (EIS)measurements. EIS measurements were analyzed by Nyquist, Bode-magnitude, Bode-phase, andAdmittance plots. Long-term stability tests were obtained by CV method using 1000 charge/dischargeperformances at a scan rate of 100 mV×s-1. The highest specific capacitance was calculated as Csp=1753.77 F×g-1at 2 mV×s-1for rGO/MoS2/PANI nanocomposite.
