Na4 Co2 O6
semiconductor· Na4 Co2 O6
Na₄Co₂O₆ is a mixed-valence sodium cobalt oxide compound belonging to the family of layered oxide semiconductors and ionic conductors. This material is primarily of research interest for energy storage and electrochemical applications, where its layered crystal structure and mixed oxidation states enable ion transport and electron conductivity. While not yet commercially widespread, sodium cobalt oxides represent a promising alternative to lithium-based systems for cost-effective battery chemistries and thermoelectric devices, particularly in applications where abundant sodium resources and lower material costs are advantageous.
