Na3 Mn5 O12

Na₃Mn₅O₁₂ is a mixed-valence manganese oxide semiconductor with a complex crystal structure containing sodium and multiple oxidation states of manganese. This compound is primarily of research and development interest for energy storage and electrochemical applications, where its layered oxide framework and ion-transport properties are being investigated as a potential cathode material or electrolyte component. While not yet widely deployed in commercial products, materials in this family are attracting attention as lower-cost and sodium-rich alternatives to conventional lithium-based battery compounds, particularly for large-scale stationary energy storage where sodium-ion chemistry offers cost and sustainability advantages.
