· Li4 Fe2 P2 O10

Li₄Fe₂P₂O₁₀ is an iron-lithium phosphate ceramic compound belonging to the phosphate family of ionic conductors and energy-storage materials. This is a research-phase material primarily investigated for solid-state battery electrolytes and lithium-ion conductor applications, where its framework structure offers potential for high ionic conductivity. Engineers consider phosphate-based lithium compounds when designing all-solid-state battery systems that require improved thermal stability, safety, and energy density compared to conventional organic liquid electrolytes.
