· JVASP-11748· Na4FeO3

Na4FeO3 is an iron-sodium oxide ceramic compound belonging to the family of mixed-metal oxides. This material is primarily of research interest rather than widespread industrial use, studied for its potential in energy storage systems, particularly in sodium-ion battery cathodes and solid-state electrolyte applications where sodium mobility and iron redox chemistry are exploited. Its significance lies in the broader effort to develop sodium-based alternatives to lithium-ion technology, offering potential cost and resource advantages, though its performance and stability characteristics require further development compared to more established ceramic systems.
