· JVASP-46237· Li4CrFe3O8

Li4CrFe3O8 is a mixed-metal oxide ceramic compound containing lithium, chromium, and iron in a spinel-related crystal structure. This material is primarily investigated in battery and energy storage research, particularly as a potential cathode or electrolyte component for advanced lithium-ion systems, though it remains largely in the experimental phase rather than established industrial production. The combination of multiple d-block metal centers in a lithium-rich oxide framework makes it relevant to researchers seeking to improve energy density, ionic conductivity, or thermal stability in next-generation electrochemical devices.
