The purpose of this study is to research and develop conducting polymer(CP) composite electrode for supercapacitor. Electrochemical capacitor(supercapacitor) cell of CP composite electrode with 1M LiClO$_4$PC bring out good capacitor performance below 4V. The radius of semicircle of CP composite cell with PAn composite electrode adding l5wt%SP270(PAnS15) and PT composite electrode adding 50wt%SP270 (PTS50) was absolutely small. The total resistance of supercapacitor cell mainly depended on internal resistance of the electrode. The discharge capacitance of supercapacitor cell with PTS50(+)/PAnS15(-) in 1st and 20th cycles was 38F/g and 28F/g at current density of 1mA/cm$^2$. Supercapacitor cell with PTS50(+)/PAnS15(-) showed good capacitance and stability with cycling.

The purpose of this study is to research and develop conducting polymer(CP) composite electrode for supercapacitor. Supercapactior cell of CP composite electrode with 1M LiClO$_4$/PC brings out good capacitor performance below 4V. The radius of semicircle of CP composite cell with PAn composite electrode adding 15Wt% SP270(PAnS15) and PT composite electrode adding 50%wt% SP270(PTS50) was absolutely small. The total resistance of supercapacitor cell mainly depended on internal resistance of the electrode. The discharge capacitance of supercapacitor cell with PTS50(+)/PAnS15(-) in 1st and 20th cycles was 38F/g and 28F/g at current density of 1mA/$\textrm{cm}^2$, respectively.
