Li2 Mg2 Mn1 Fe1 P4 O16

Li2Mg2Mn1Fe1P4O16 is a mixed-metal phosphate ceramic compound belonging to the polyphosphate family, combining lithium, magnesium, manganese, and iron cations in a phosphate framework. This composition is primarily of research and development interest for energy storage applications, particularly as a potential cathode or electrolyte material in lithium-ion battery systems where the multi-metal composition offers opportunities for tuning electrochemical performance and thermal stability. The material's mixed-valent transition metals (Mn, Fe) and lithium content make it a candidate for next-generation battery chemistries seeking alternatives to traditional layered oxides, though it remains an exploratory compound rather than a widely commercialized material.
