O2 Na1 Fe1
semiconductor· O2 Na1 Fe1
Sodium iron oxide (Na₁Fe₁O₂) is an intermetallic compound belonging to the semiconductor/ionic conductor family, combining alkali metal and transition metal elements in a layered oxide structure. This material is primarily of research interest for energy storage and electrochemistry applications, where mixed-valence iron oxides with sodium are investigated as potential cathode materials for sodium-ion batteries and as ionic conductors for solid-state electrochemical devices. The combination of sodium and iron offers advantages over lithium-based systems in terms of raw material abundance and cost, making it notable for next-generation battery chemistries despite still being largely in the development phase.
