NiO2F

NiO₂F is an experimental nickel oxide fluoride ceramic compound that combines nickel oxide with fluorine, creating a mixed-anion ceramic with potential electrochemical and structural applications. This material remains primarily in the research phase, investigated for energy storage, catalysis, and functional ceramic applications where the fluorine dopant can modify electronic properties and ionic conductivity compared to conventional nickel oxides. Interest in this compound class stems from the ability to tailor defect chemistry and electrochemical performance through fluorine incorporation, though industrial adoption and manufacturing maturity remain limited.
