· JVASP-140708· Na2Co3O4

Na₂Co₃O₄ is an inorganic ceramic compound containing sodium, cobalt, and oxygen, belonging to the mixed-valence oxide family. This material is primarily investigated in research contexts for electrochemical energy storage applications, particularly as a cathode material or electrocatalyst, where its cobalt-oxide framework and sodium-ion chemistry offer potential advantages in battery systems and catalytic processes. Its selection over conventional alternatives is driven by abundance of sodium, cost considerations, and the electrochemical activity of cobalt oxides in energy conversion devices.
