Li2 Fe3 Sb1 O8

Li₂Fe₃Sb₁O₈ is an iron antimonate lithium oxide compound—a mixed-metal oxide semiconductor in the family of complex transition-metal oxides. This is a research-stage material being investigated for energy storage and catalytic applications, particularly as a potential cathode material or catalytic support in lithium-ion battery systems and electrochemical devices. Interest in this compound stems from the combination of lithium, iron, and antimony oxides, which can offer tunable electronic properties and structural stability; it represents an emerging strategy to develop alternative cathode chemistries beyond conventional layered oxide systems.
