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.
