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 metalair battery. The physical and electrochemical properties of TiO2 samples were investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM) and cyclic voltammetry (CV). | VNU Journal of Science: Mathematics – Physics, Vol. 32, No. 3 (2016) 49-55 TiO2 Fabricated from Vietnamese Ilmenit Applying for Battery Anode Doan Ha Thang1,*, Vu Manh Thuan2, Bui Thi Hang2,* 1 Department of High Technology, Ministry of Science and Technology, Hanoi, Vietnam 2 International Institute for Materials Science, Hanoi University of Science and Technology, Hanoi, Vietnam Received 15 July 2016 Revised 25 August 2016; Accepted 09 September 2016 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 metalair battery. The physical and electrochemical properties of TiO 2 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 TiO 2/AB and TiO2/Fe2O3/AB electrodes were investigated. The prepared TiO2 could be a promising candidate for a metal/air battery anode. Keywords: TiO2 particles, plasma, carbon additive, TiO2-Fe2O3/AB composite electrode, Fe/air battery anode. 1. Introduction As a versatile functional material, titanium dioxide (TiO2) has a wide range of applications, such as solar cells, photocatalytic water splitting, gas sensing, and so on [1-3]. Besides that, TiO2-based materials are of great interest for energy storage and conversion devices, in particular rechargeable lithium ion batteries (LIBs). Due to its excellent advantages of low cost, nontoxicity, environmentally benign, thermally and chemically stability, TiO2 has been developed to be a promising anode material for LIBs [4]. Lithium-ion batteries are some of the most promising batteries because of their high energy density, low maintenance
