Na2CoO3

Na2CoO3 is a sodium cobalt oxide ceramic compound belonging to the family of transition metal oxides with layered crystal structures. This material is primarily studied in research contexts for electrochemical and thermoelectric applications, particularly as a cathode material in sodium-ion batteries and as a potential thermoelectric generator component, where its cobalt-oxygen framework enables ion transport and charge carrier mobility. Its layered structure and variable oxidation states make it notable compared to conventional lithium-based systems for cost-sensitive energy storage and solid-state power generation, though development remains largely in the laboratory and pre-commercialization phase.
