· JVASP-94793· Na3PSe4

Na3PSe4 is an inorganic ceramic compound composed of sodium, phosphorus, and selenium—a phosphoselenide material that belongs to the family of solid-state ionic conductors. While primarily investigated in research contexts rather than established industrial production, this material is of interest for solid electrolyte applications in advanced energy storage systems, particularly in all-solid-state batteries where its ionic conductivity and ceramic stability are valued. Its selection would appeal to engineers designing next-generation energy devices or exploring alternative electrolyte chemistries where traditional liquid electrolytes present safety, stability, or thermal management challenges.
