Li2 O14 P4 Fe2

Li₂O₁₄P₄Fe₂ is an iron-containing lithium phosphate compound that functions as a semiconductor, belonging to the family of mixed-metal phosphate ceramics. This material is primarily of research interest for energy storage and electrochemical applications, where its ionic conductivity and structural framework make it a candidate for solid-state battery electrolytes and lithium-ion transport media. Compared to conventional oxide electrolytes, iron-doped lithium phosphates offer potential advantages in thermal stability and tunability of electronic properties, though this composition remains largely experimental and is not yet established in high-volume industrial production.
