· Li4 Cr2 Fe2 O8

Li₄Cr₂Fe₂O₈ is an experimental mixed-metal oxide semiconductor combining lithium, chromium, and iron in a single crystal structure. This compound belongs to the family of complex oxides being investigated for energy storage and catalytic applications, where the multi-valent transition metals (Cr and Fe) enable tunable electronic and ionic properties. Research interest centers on its potential as a cathode material for advanced lithium-ion batteries or as an electrocatalyst, though it remains primarily a laboratory compound without established commercial production.
