Na3V2(PO4)2F3 (NVPF) is a highly promising, low-cost cathode material for Sodium-Ion Batteries (SIBs). It belongs to polyanion family of electrode materials and is distinguished by its stable, three-dimensional NASICON (Na super ionic conductor) structure. The main difference is fluorine-induced high voltage plateau (3.8 V) compared to NVP cathode material (3.4 V). It offers a high theoretical capacity of 128 mAh/g (for the two-electron Na+ extraction), translating to a high theoretical energy density (up to 500 Wh/kg).
