Abstract

In this work, vanandium(III) oxide nanoparticles (V₂O₃ NPs) were prepared via the heat treatment of hydrothermally prepared vananium(IV) oxide (VO₂) NPs in a reducing atmosphere. The V₂O₃ NPs had a spherical shape with a size of less than 50 nm as the initial VO₂ NPs. These V₂O₃ NPs without any conductive additives showed both long-term structural and electrochemical cycling stability (~142 mA h g⁻¹ of reversible capacity up to 400 cycles) for Li ion battery anodes.
