A detailed description of phase transitions occurring in the LixV2O5 active material in a composite electrode (0≤x < 2) is provided here for the first time using Raman spectroscopy. The successive emergence of the various phases governing the electrochemical properties of this cathode material is spectroscopically observed. This work demontrates that Raman spectroscopy constitutes a powerful tool to explore the structural changes induced by electrochemical Li insertion-extraction reactions in electrode materials for lithium batteries.
