· JVASP-46644· Li14Mn2O9

Li14Mn2O9 is a lithium-manganese oxide ceramic compound being investigated primarily in battery and energy storage research. This material is notable as a potential cathode or electrolyte component in lithium-ion systems, where its mixed-valence manganese chemistry and lithium-rich composition make it a candidate for improving energy density and ionic conductivity compared to conventional oxide frameworks. As an experimental compound rather than a commercialized material, it represents the class of high-capacity lithium oxides being explored to advance next-generation battery performance.
