Abstract
The Polyaniline (PANI) film is prepared on graphite electrode (graphite/Pani) in the solution consisting of aniline 0.1 M and acid sulfuric (H2SO4) 0.75 M by the electrochemical methods. The Zn-Pani rechargeable battery was prepared from purity Zinc and graphite/Pani as a negative and a positive electrode respectively. These electrodes were immersed in the electrolysis containing 1.0 M ZnCl2 and 0.5 M NH4Cl. The battery is charged and discharged by a constant current (galvanostatic). The factors affecting the cycle-life and the open-circuit potential (OCV) of Zn–polyaniline (PANI) rechargeable batteries are studied by means of electrochemical techniques and analyses of electrode surface. Results demonstrated a high current efficiency and a long cycle – life time of the prepared Zinc-Pani battery.
