Abstract

A novel fluoro-polyanionic cathode LiV0.5Fe0.5PO4F is synthesized via a wet ball-milling-assisted solid state method. Cationic ordering of V3+ and Fe3+ results in a single phase behaviour over the lithium composition range of LixV0.5Fe0.5PO4F (0 < x < 0.5) as revealed by X-ray diffraction analysis and electrochemical tests. This finding offers a versatile strategy of introducing single-phase behaviour in promising fluoro-polyanionic compounds exhibiting two-phase mechanisms.
