· 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.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
