TiO2 Fabricated from Vietnamese Ilmenit Applying for Battery Anode

Abstract

Abstract:  In this study, TiO₂ was fabricated from Vietnamese ilmenite using plasma treatment. It was used as the active material in the metal-air battery to find the better anode material for metal-air battery. The physical and electrochemical properties of TiO₂ samples were investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM) and cyclic voltammetry (CV). The obtained results showed that pure TiO₂ fine powder was successfully fabricated by plasma treatment and it can be used as the anode material in metal-air batteries. The influence of Acetylene Black (AB) additive on the electrochemical behaviors of TiO₂/AB and TiO₂/Fe₂O₃/AB electrodes were investigated. The prepared TiO₂ could be a promising candidate for a metal/air battery anode.
