Abstract
Abstract Electrode material is a decisive component that affects the overall performance of lithium‐ion batteries (LIBs). Therefore, many researchers are committed to developing electrode materials with better performance. Metal‐organic frameworks (MOFs) can provide a metal source for phosphate synthesis due to its composition. In this work, a new conversion anode material, vanadium (III) metaphosphate V(PO 3 ) 3 , is successfully prepared by adding red phosphorus into the synthesized V‐MOF and calcination. V(PO 3 ) 3 can reach a high initial discharge capacity of 1068 mA h g −1 and a high reversible capacity of 475 mA h g −1 at a current density of 100 mA g −1 . Remarkably, the reversible capacity of 430 mA h g −1 was still maintained after the current density returned from 2000 to 100 mA g −1 .
