Li4 Mn1 Fe3 O8

Li₄Mn₁Fe₃O₈ is a mixed-metal oxide semiconductor compound combining lithium, manganese, and iron in a spinel-related crystal structure. This is primarily a research material being investigated for energy storage and electrochemical applications, particularly as a cathode material or electrolyte component in lithium-ion batteries and solid-state battery systems. The material is notable for its potential to offer improved energy density, thermal stability, or cost reduction compared to conventional cathode materials like LiCoO₂, though it remains largely in development phases rather than mainstream production.
