Hybrid electrochemical capacitors based on polyaniline and activated carbon e…

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 cap…
