Hybrid electrochemical capacitors based on polyaniline and activated carbon electrodes

---

Abstract
The performance of a newly designed, polyaniline–activated carbon, hybrid electrochemical capacitor is evaluated. The capacitor is prepared by using polyaniline as a positive electrode and activated carbon as a negative electrode. From a constant charge–discharge test, a specific capacitance of 380 F g­­ ­­-1 is obtained. The cycling behaviour of the hybrid electrochemical capacitor is examined in a two-electrode
cell by means of cyclic voltammetry. The cycle-life is 4000 cycles. Values for the specific energy and specific power of 18 Wh kg -1 and 1.25 kW kg-1, respectively, are demonstrated for a cell voltage between 1 and 1.6 V.
