ceramic

· JVASP-59208· Na5MnO4

Na5MnO4 is an inorganic ceramic compound containing sodium, manganese, and oxygen, belonging to the family of mixed-metal oxides. This material is primarily of research and development interest, investigated for energy storage and electrochemical applications where manganese oxides offer redox activity and ionic conductivity. While not yet widely deployed in mainstream engineering, sodium-manganese oxides are explored as potential cathode materials for sodium-ion batteries and as oxygen evolution catalysts, representing an alternative to lithium-based systems with potential cost and sustainability advantages.
