Li2 Mn4 O8

Li₂Mn₄O₈ is a lithium-manganese mixed oxide ceramic compound that functions as a semiconductor material. It belongs to the family of layered transition metal oxides and is primarily of interest in electrochemical energy storage and catalysis research. This material is investigated for potential use in lithium-ion battery cathodes and oxygen reduction catalysts, where its layered structure and manganese redox activity offer advantages over simpler binary oxides, though it remains largely in the research and development phase rather than widespread industrial production.
