In this study, 3 different materials were combined to form hybrid nanocomposite for SupercapBattery 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 of nanocomposites. 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, and Admittance plots. Long-term stability tests were obtained by CV method using 1000 charge/discharge performances at a scan rate of 100 mV×s-1 . The highest specific capacitance was calculated as Csp= 1753.77 F×g-1 at 2 mV×s-1 for rGO/MoS2/PANI nanocomposite.
