Polypyrrole/carbon (PPy/C) composite doped with organic anion p-toluenesulfonate (pTS) is utilized as an electrode in supercapacitor for energy storage application. The surface initiated in-situ chemical oxidative polymerization yields a composite material PPy/C in the presence of varying concentrations of pTS. The novelty of the present invention lies in the doping of PPy/C composite with organic anion pTS and consequent enhancement of its electrochemical activity and stability. The conjugation length and electrical conductivity of pTS doped PPy/C composites increase with the increase in dopant concentration. The pTS doped PPy/C composite synthesized using equimolar concentration (0.1 M) of pTS to pyrrole shows the maximum specific capacitance of 395 F/g in 0.5 M Na.sub.2SO.sub.4 aqueous solution with significant stability 95% capacitance retention after 500 cycles.
