Li4 Mn2 P4 O14

Li₄Mn₂P₄O₁₄ is a lithium manganese phosphate compound belonging to the polyphosphate ceramic family, of primary interest as a research material for energy storage and electrochemical applications. While not yet a mainstream industrial material, this compound is studied for potential use in lithium-ion battery cathodes and solid-state electrolyte systems due to its mixed-valence manganese framework and ionic conductivity characteristics. Engineers and materials researchers evaluate such polyphosphate compounds as alternatives to conventional layered oxides when seeking materials with enhanced thermal stability, reduced cobalt dependency, or improved structural cycling performance in electrochemical devices.
