· Na3 P1 S4

Na₃PS₄ is an inorganic semiconductor compound belonging to the family of alkali metal phosphorus sulfides, which are primarily of research interest rather than established commercial materials. This compound is being investigated for potential applications in solid-state electrolytes and energy storage systems, where its ionic conductivity and structural stability at operating temperatures could offer advantages over conventional liquid electrolytes. While not yet widely deployed in production, materials in this chemical family are notable for their potential to enable safer, higher-energy-density battery systems and their thermal stability compared to organic polymer-based alternatives.
