· JVASP-48274· Li2Mn2C3O9

Li2Mn2C3O9 is a lithium-manganese oxide carbonate ceramic compound that belongs to the family of lithium-based metal oxides with potential electrochemical functionality. This material is primarily of research interest rather than established in widespread industrial production, with applications being explored in energy storage systems—particularly as a cathode material or electrolyte component in lithium-ion batteries and related electrochemical devices. Its mixed-valence manganese chemistry and lithium content make it a candidate for studies on ion transport and redox activity, though practical adoption depends on demonstrating advantages in cycle life, thermal stability, or cost compared to conventional layered oxide or spinel cathodes.
