Abstract: γ-LixV2O5 (x = 0.9-1) was synthesized at 350 °C. The material was characterized by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). The synthesis reactions were studied by thermogravimetric analysis (TGA). The composition of γ-LixV2O5 was determined by atomic absorption spectrophotometry (AAS) and inductively coupled plasma-atomic emission spectrophotometry (ICP-AES). Its electrochemical performance as cathode active materials was studied by galvanostatic charge-discharge and cycle voltammetry. γ-LixV2O5 could deintercalate lithium ion reversibly. The potential vs Li+/Li electrode was from 2.6 to 4.0 V. γ-LixV2O5 has potential as starting electrode active material in lithium ion batteries. © 1999 American Chemical Society.
