· Na14 Co2 O9

Na₁₄Co₂O₉ is a mixed-valence sodium cobalt oxide ceramic compound belonging to the family of layered perovskite-related oxides. This material is primarily of research interest for electrochemical and thermoelectric applications, where its unique crystal structure and ionic conductivity make it a candidate for solid-state electrolytes, energy storage systems, and temperature-dependent electronic devices. While not yet widely deployed in mainstream commercial products, sodium cobalt oxides are being explored as alternatives to lithium-based systems due to sodium's abundance and lower cost, and this particular composition is notable within that family for its structural stability and mixed-valence cobalt chemistry.
