· JVASP-42576· Li5Fe4O8

Li5Fe4O8 is a lithium iron oxide ceramic compound that belongs to the class of mixed-valence transition metal oxides, of primary interest in electrochemical and solid-state energy storage research. This material is investigated as a potential cathode or electrolyte component in advanced lithium-ion batteries and solid-state battery systems, where its layered or spinel-like crystal structure and lithium-ion conductivity properties are exploited to improve energy density and thermal stability compared to conventional oxide cathodes. While not yet in widespread commercial production, Li5Fe4O8 represents the broader family of lithium transition-metal oxides being developed to address the performance and safety demands of next-generation energy storage devices.
