· JVASP-112826· Li4Mn5FeO12

Li4Mn5FeO12 is a mixed-valence oxide ceramic composed of lithium, manganese, and iron oxides, belonging to the family of layered or spinel-structured lithium metal oxides. This compound is primarily investigated as a cathode material for lithium-ion battery systems, where the combination of manganese and iron redox activity offers potential advantages in energy density and cost reduction compared to conventional nickel-cobalt cathodes. The material represents an area of active research in battery chemistry, with particular interest in applications requiring higher voltage operation and improved thermal stability, though it remains largely in development stages rather than widespread commercial deployment.
