Na2 Co4 O6
semiconductor· Na2 Co4 O6
Na2Co4O6 is a layered metal oxide semiconductor belonging to the class of sodium cobalt oxides, which exhibit mixed-valence cobalt chemistry and ionic conductivity in the sodium sublattice. This material is primarily of research interest for energy storage and electrochemical applications, particularly in sodium-ion batteries and thermoelectric devices, where its layered structure enables sodium-ion transport and its electronic properties can be tuned through doping or structural modification. Compared to lithium-based counterparts, sodium cobalt oxides offer potential cost and abundance advantages, though the material remains in development stages for commercial deployment.
