Li2Mn3FeO8

Li2Mn3FeO8 is a lithium-based mixed-metal oxide ceramic belonging to the spinel or layered oxide family, combining manganese and iron as active redox centers. This compound is primarily investigated as a cathode material for lithium-ion batteries and emerging energy storage systems, where the multi-valent transition metals enable high lithium extraction capacity and structural stability during charge-discharge cycling. The material represents a research-stage alternative to conventional lithium cobalt oxide cathodes, offering potential cost advantages and improved thermal stability through compositional substitution, though it remains under development for commercial adoption.
