Abstract

The purpose of this study is to research and develop conducting polymer(CP) composite electrode for supercapacitor. The radius of semicircle of CP composite cell with polyaniline(PAn) composite electrode adding 30wt% acetylene black was small. The total resistance of supercapacitor cell mainly depended on internal resistance of he electrode. The discharge capacitance of supercapacitor cell with PAn composite electrode adding 30wt% acetylene black in 1st and 50th cycles was 27F/g and 31F/g at current density of 1mA/$\textrm{cm}^2$, respectively. Supercapacitor cell with PAn composite electrode adding 30wt% acetylene black showed a good cycliability. Supercapacitor cell of CP composite electrode with 1M LiClO$_4$/PC brings out god capacitor performance below 4V.
