High performance battery–supercapacitor hybrid energy storage system based on self-doped polyaniline nanofibers

---

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 combination of an
asymmetric supercapacitor (AC/SDPA) and a secondary battery (Zn/SDPA) in a single cell configuration
and same electrolyte. Different electrochemical methods including cyclic voltammetry, galvanostatic
charge–discharge and rate charge–discharge studies are carried out to characterize electrochemical performances of the hybrid system. Based on the obtained results, the hybrid system shows specific capacity,
specific energy, specific power and maximum power values of 215 Ah kg−1, 204 Wh kg−1, 863 W kg−1 and
8909 W kg−1, respectively, at a current density of 2.5 mA cm−2.

Keywords: Hybrid power source, Supercapacitor, Secondary battery, Self-doped polyaniline nanofiber
