· Li4 Fe2 Cu2 P4 O16

Li4Fe2Cu2P4O16 is a mixed-metal phosphate ceramic compound combining lithium, iron, copper, and phosphate groups in a rigid oxide framework. This material belongs to the polyphosphate family and is primarily of research interest for energy storage and electrochemical applications, particularly as a potential cathode material or electrolyte component in advanced lithium-ion and solid-state battery systems. Its mixed-valence transition metal composition (Fe and Cu) offers tunable electronic and ionic transport properties, making it a candidate for next-generation high-energy-density battery architectures where conventional oxide or olivine phosphates may have limitations.
