Li4Mn2OF7 is a mixed-valence lithium manganese oxyfluoride ceramic compound being investigated as a cathode material for advanced lithium-ion battery systems. This research-phase material is of interest to battery electrochemists because the fluorine substitution and mixed manganese oxidation states can potentially enhance electrochemical performance, cycle stability, and thermal safety compared to conventional oxide cathodes. The material represents the broader class of high-energy-density layered oxyfluorides being developed to meet demanding requirements in electric vehicle and grid-scale energy storage applications.
