Abstract
The purpose of this paper is to develop feasible composite electrodes with a long cycle life and large specific capacitance and to investigate optimal ratio between aniline and carbon aerogels (CA) materials. The characterization of the composite electrode materials was studied by using scanning electron microscopy (SEM), electrochemical impedance spectroscopy, cyclic voltammetry (CV) and the constant charge-discharge. The specific capacitance of the composite electrode materials, measured using cyclic voltammetry at scan rate of 1mV•s-1, was found to be 1139.66F•g-1. For a simple supercapcitor, the highest specific capacitance (127.53 F•g-1 at 30mA) is obtained at ratio between aniline and CA is 1:4.
