Na3FeO3

Na3FeO3 is an iron-sodium oxide ceramic compound that belongs to the family of mixed-metal oxides with potential electrochemical and structural applications. This material is primarily investigated in research contexts for energy storage systems, particularly as a cathode material or electrolyte component in sodium-ion batteries and solid-state electrochemical devices, where the combination of sodium and iron offers cost advantages over lithium-based alternatives. Its selection in advanced battery chemistry is driven by the abundance and lower cost of sodium compared to lithium, making it a candidate material for large-scale energy storage applications, though it remains largely experimental rather than widely commercialized.
