The characterization and performance of the supercapacitor has been studied by FTIR, Cyclic Voltammetry and AC Impedance spectroscopy. The supercapacitor showed a maximum specific capacitance of 121 F g-1 at a scan rate of 10 mV s-1. The time constant calculated for the supercapacitor through the active-reactive power behavior measurement was 12 milliseconds indicating the suitability of the system for efficient use at low frequency range. © 2007 Springer Science+Business Media, LLC.Cyclic voltammetryFourier transform infrared spectroscopyReactive powerRedox reactionsStainless steelThiopheneAC Impedance spectroscopyPower behavior measurementSupercapacitorsElectrochemical electrodes
