· JVASP-48601· Na5Mn7O16

Na5Mn7O16 is a sodium manganese oxide ceramic compound belonging to the family of mixed-valence manganese oxides, which are primarily of research and development interest rather than established commercial materials. This compound and related phases are investigated for energy storage and electrochemical applications, particularly as cathode materials in sodium-ion batteries and as catalysts, where the layered or tunnel structure can facilitate ion transport. The material represents an alternative chemistry to lithium-based systems, making it potentially valuable for cost-sensitive, large-scale energy storage where sodium abundance and supply chain stability offer advantages over conventional lithium compounds.
