Li4 Fe5 O10

Li₄Fe₅O₁₀ is an iron-lithium mixed oxide ceramic compound belonging to the family of lithium iron oxides, which are of significant interest in energy storage and electrochemical applications. This material is primarily investigated in research contexts as a potential cathode material or active component in lithium-ion battery systems, where its iron content provides redox activity and lithium mobility enables ionic conduction. While not yet widely deployed in commercial products compared to more established lithium iron phosphate (LFP) alternatives, this oxide composition represents an area of active development for next-generation battery chemistries seeking improved energy density, thermal stability, or cost advantages.
