Abstract

In this work, hybrid 3 different materials (rGO, CuO and PPy) were formed by hybrid nanocomposites in 2032 coin cell for Supercapbattery applications. Pseudocapacitance behavior was obtained for transition metal oxides of copper (II) oxide (CuO) and conducting polymer of polypyrrole (PPy). Moreover, electrical double layer capacitance (EDLC) behavior was supplied by reduced graphene oxide (rGO) in nanocomposite. 3 different electrochemical performances were tested by cyclic voltammetry (CV), galvanostatic charge/discharge (GCD) and electrochemical impedance spectroscopic measurements (EIS). EIS measurements were given by 4 different plots, which are Nyquist, Bodemagnitude, Bode-phase and Admittance plots. Stability test was also performed by CV method using 1000 charge/discharge performances at a scan rate of 100 mV×s-1 . The highest specific capacitance was obtained as Csp= 2761.63 F×g-1 at 2 mV×s-1 (electrode weight was measured as 43.8 mg)
