· JVASP-40904· Li2SnP2O7

Li₂SnP₂O₇ is an inorganic ceramic compound combining lithium, tin, and phosphate oxides, belonging to the family of phosphate-based ceramics. This material is primarily of research interest for solid-state lithium-ion battery applications, where phosphate ceramics are investigated as potential solid electrolytes or electrolyte additives due to their ionic conductivity and structural stability. While not yet widely deployed in commercial products, compounds in this family are notable for their potential to enable high-energy-density batteries with improved thermal and chemical stability compared to conventional liquid electrolyte systems.
