Na2Mn2O3

Sodium manganese oxide (Na2Mn2O3) is a mixed-valence ceramic compound belonging to the family of transition metal oxides, where manganese exists in multiple oxidation states within a sodium-containing lattice structure. This material has attracted research interest primarily in energy storage and catalytic applications, particularly as a cathode material or precursor in sodium-ion battery systems and as a catalyst support in oxidation reactions. Compared to lithium-based systems, sodium-containing manganese oxides offer potential cost and resource advantages, though the material remains largely in development phases for commercial deployment.
