· JVASP-55316· Na4Mn2O5

Na₄Mn₂O₅ is a mixed-valent manganese oxide ceramic compound containing sodium, belonging to the family of layered metal oxides studied for electrochemical and catalytic applications. This material is primarily investigated in research contexts for energy storage systems (particularly sodium-ion battery cathodes) and as a catalyst precursor, where its mixed manganese oxidation states and layered crystal structure offer potential advantages in ion transport and redox cycling compared to single-phase oxides.
