Synthesis and Electrochemical Properties of Nanorod Polyaniline/Activated Carbon Composites for Electrochemical Capacitor

In this study, polyaniline (PANI) was prepared by electrochemical method on the surface of active carbon (AC) electrodes. The physical and electrochemistry properties of AC/PANI composite compared with pure AC electrode were investigated by scanning electronic microscope (SEM), galvanostatic charge/discharge test and electrochemical impedance spectroscopy (EIS). The AC/PANI composite electrodes showed much higher specific capacitance (624 F•g-1), better power characteristics and were more promising for application in capacitor than pure AC electrodes.
