VOF2 is a vanadium oxyfluoride ceramic compound belonging to the family of mixed-anion oxides that combine oxygen and fluorine coordination around vanadium cations. This material is primarily investigated in research contexts for applications requiring a combination of ionic conductivity and chemical stability, particularly in electrochemical systems and solid-state energy storage where the fluoride component can enhance lithium-ion mobility and the vanadium redox chemistry enables multi-electron transfer processes.
