Na3V2(PO4)2O2F (NVPOF) 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, which features both oxide (O2-) and fluoride (F-) ions within its framework. The fluorine- and oxygen- induced high voltage plateau (3.8 V) compared to NVP cathode material (3.4 V). It offers a high theoretical capacity of 130 mAh/g and provides a high theoretical energy density (up to 500 Wh/kg).
