Electrochemical properties of Fe2O3 electrode in alkaline solution containing K2S additive

Abstract

Abstract:To find the suitable materials for Fe/air battery anode, in this study Fe 2 O 3 electrodes were prepared using Fe 2 O 3 nanoparticles. The size and morphology of Fe 2 O 3 material were observed by scanning electron microscope (SEM). The electrochemical properties of the Fe 2 O 3 electrode in alkaline solution were investigated by using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The effects of K 2 S additive in electrolyte solution on the electrochemical characteristics of Fe 2 O 3 electrodes were also investigated. The obtained results show that the additive strongly affected on the impedance, redox reaction rate and cyclability of Fe 2 O 3 electrode.
