· Na5Al3F14

Na5Al3F14 is a sodium aluminum fluoride compound that belongs to the family of fluoride-based ceramics and ionic materials. This material is primarily investigated in research contexts for applications requiring high ionic conductivity and chemical stability, particularly in solid electrolytes and fluoride-ion battery systems where its fluoride chemistry enables fast anion transport. Engineers consider this material when designing high-temperature electrochemical devices or solid-state battery systems where conventional liquid electrolytes are impractical, though it remains largely in the development phase rather than established high-volume production.
