Research Progress in Lithium Vanadium Oxides as Cathode Materials

Abstract:

The progress in lithium vanadium oxides used as cathode for lithium secondary batteries were reviewed, including vanadium oxides V2O5 and LiV3O8, vanadium oxides of single valence change LiNiVO4, and of double valences change FeVO4. The structures, the methods of preparation and electrochemical performances of these oxides were summarized. The charge-discharge mechanism and modification research status of FeVO4 were introduced
