· Li4(FeO2)9

Li4(FeO2)9 is an iron-lithium oxide ceramic compound that belongs to the family of lithium-based metal oxides. This material is primarily investigated in battery and electrochemistry research, where it functions as a potential cathode material or lithium-ion conductor in advanced energy storage systems. While not yet widely deployed in commercial applications, compounds in this family are valued for their potential to improve lithium-ion battery performance, particularly in high-energy-density and solid-state battery architectures where stability and ionic conductivity are critical.
