· O12 Na1 Mn7

O12Na1Mn7 is a mixed-valent manganese oxide compound with sodium incorporation, belonging to the family of layered or tunnel-structured manganese oxides commonly studied as cathode materials and ion-intercalation hosts. This composition is primarily encountered in materials science research rather than established industrial applications, where it is investigated for electrochemical energy storage, particularly in sodium-ion battery systems and supercapacitors that exploit manganese oxide's redox activity and structural flexibility. The sodium content and manganese-rich stoichiometry make this compound notable for its potential in post-lithium battery chemistries and as a low-cost alternative to cobalt-based cathodes, though optimization of crystal structure, cycling stability, and rate performance remains an active research focus.
