Here, we demonstrate a new, rapid, and flexible hydrothermal method using the V2O5 and LiOH as the precursors to synthesize Li3VO4. The ratios of precursor of V2O5 and LiOH can be changed in a wide range to control different preferred facets and morphologies, and the reason has been discussed from the structure of Li3VO4. The electrical performance of the Li3VO4 has also been systematically investigated. The thus-synthesized Li3VO4 exhibits significantly improved rate capability and cycling life compared with commercial graphite, synthesized Li4Ti5O12, and previously reported results on Li3VO4.
