· JVASP-44706· Li4FeCo3O8

Li4FeCo3O8 is a mixed-metal lithium oxide ceramic compound containing iron and cobalt, belonging to the family of lithium-based transition metal oxides. This is primarily a research material being investigated for energy storage and electrochemical applications, particularly as a potential cathode material or electrode component in advanced lithium-ion and solid-state battery systems. The dual transition metal composition (Fe and Co) is of interest for tuning electrochemical activity and structural stability compared to single-metal alternatives, though the material remains largely in academic development rather than established industrial production.
