Vanadium Metaphosphate V(PO ₃ ) ₃ Derived from V‐MOF as a Novel Anode for Lithium‐Ion Batteries

In this work, a new conversion anode material, vanadium metaphosphate V(PO3)3, is successfully prepared by adding red phosphorus into the synthesized V-MOF and calcination. V(PO3)3 obtains a high initial discharge specific capacity of 1068 mA h g−1 at a current density of 100 mA h g−1. In addition, the material obtains an ideal coulombic efficiency close to 100 % in 100 cycles, indicating that V(PO3)3 has a completely reversible lithium ion storage.
