Abstract. A hybrid asymmetric electrochemical supercapacitor is constructed by employing two different nanostructured conducting polymers of polypyrrole (PPy) and self-doped polyaniline (SDPA). Different electrochemical methods, including cyclic voltammetry, galvanostatic charge–discharge and electrochemical impedance spectroscopy (EIS), are performed to characterize the electrochemical per…
Abstract. Nanostructured self-doped polyaniline (SDPA) is prepared from an aqueous solution of aniline and maminobenzoic acid using an electrochemical method onto a stainless steel electrode. This electrode employed as a positive shared electrode in the construction of a hybrid battery–supercapacitor energy storage system AC/SDPA/Zn. This hybrid system is constructed using a parallel combi…
