Abstract

Li₃VO₄ synthesized by ultrasonic spray pyrolysis was studied as a new anode material for lithium-ion batteries. Li₃VO ₄ sample heated up to 500°C has a round shape and smaller size compared with the samples synthesized by the solid-state reaction and solution-based precipitation. Compared to previously reported results, enhanced capacities and rate capabilities were obtained. Charge and discharge capacities of 250 mAh g^?1 after 100th cycle and excellent cyclabililties were observed. The average potentials for the charge and discharge curves are found to be lower than those of Li₄Ti₅O₁₂. New crystallographic planes that appear after the lithiation were identified by XRD and T.E.M. studies.
