Li1 Fe6 O7 F5

Li1Fe6O7F5 is a mixed-valence iron oxide fluoride ceramic compound containing lithium, representing an experimental material in the family of transition metal oxyfluorides. This composition is primarily of research interest for energy storage and electrochemical applications, particularly as a potential cathode material for lithium-ion batteries, where the combination of iron and fluorine can enable high charge capacity and structural stability. The material remains largely in the development phase; engineers would consider it when exploring advanced battery chemistries that demand improved energy density or thermal stability compared to conventional layered oxide cathodes.
