Na12 Mn4 O12

Na12Mn4O12 is a mixed-valence manganese oxide compound with a layered or tunnel crystal structure, belonging to the class of transition metal oxides used in electrochemical and catalytic applications. This material is primarily investigated in research contexts for energy storage devices (particularly sodium-ion batteries and supercapacitors) and catalysis, where the multiple oxidation states of manganese enable reversible electron transfer and active site generation. Its appeal lies in the abundance and cost-effectiveness of sodium and manganese compared to lithium-based alternatives, making it a candidate for next-generation electrochemical devices, though it remains largely in the experimental phase rather than widespread industrial production.
