Ni6 O2 F10

Ni₆O₂F₁₀ is a mixed-valence nickel oxide fluoride compound belonging to the family of transition metal oxyfluorides, which are layered ionic solids combining both oxide and fluoride ligands. This material is primarily of research interest for energy storage and catalytic applications, particularly in battery electrolytes, solid-state ionic conductors, and emerging electrochemical devices where the fluoride component enhances ionic mobility and the nickel oxide framework provides redox activity. While not yet a mainstream industrial material, oxyfluoride semiconductors like this represent an important class for next-generation energy storage systems and fluoride-based solid electrolytes that can outperform conventional oxide ceramics in ion conductivity.
