Li2Fe5O10

Li2Fe5O10 is an iron-lithium oxide ceramic compound belonging to the family of mixed-valence iron oxides, primarily of research and development interest rather than established commercial production. This material is investigated for energy storage and electrochemical applications, particularly in lithium-ion battery cathodes and solid-state battery systems, where its layered structure and mixed oxidation states of iron offer potential for lithium intercalation and ionic transport. Engineers evaluate this compound where high energy density, thermal stability, or alternative cathode chemistries are needed to complement or replace conventional lithium iron phosphate (LFP) or layered oxide systems.
