· JVASP-35178· Na3LiP2O7

Na3LiP2O7 is a mixed alkali phosphate ceramic compound combining sodium, lithium, and phosphate ions in a crystalline structure. This material is primarily investigated in research contexts as a solid electrolyte and ionic conductor for advanced battery systems, particularly solid-state lithium-ion battery designs where high ionic conductivity at moderate temperatures is desirable. Its mixed-cation composition offers potential advantages in ion transport and structural stability compared to single-alkali phosphate alternatives, making it relevant for next-generation energy storage applications where conventional liquid electrolytes present safety or performance limitations.
