Development and characterization of pani/go/zno supercapacitor electrodes using electrodeposition

Abstract

This study examines the development and characterization of PANI/GO/ZnO composite electrodes for supercapacitors using electrodeposition techniques. Samples of PANI, PANI/GO, PANI/ZnO, PANI/GO/ZnO were synthesized and evaluated. Electrochemical performance was assessed using cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), and electrochemical impedance spectroscopy (EIS). Structural analyses were conducted with Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD). Results show that PANI/GO/ZnO composites offer improved electrochemical performance with an efficiency of 139 %, an energy of 9.8 Wh/kg,specific capacitance of 359 F/g and a discharge time of 209.8 secondes. These results provide insights for optimizing electrodeposition parameters to enhance supercapacitor efficiency.
