· Li3 Fe2 Cu2 O8

Li₃Fe₂Cu₂O₈ is an experimental mixed-metal oxide semiconductor combining lithium, iron, and copper cations in a complex crystal structure. This compound belongs to the family of layered or spinel-related oxides under investigation for energy storage and electronic applications, where the multiple redox-active metal sites (Fe²⁺/Fe³⁺ and Cu²⁺/Cu⁺) enable tunable electrochemical and optical behavior. While primarily a research material rather than a commercial product, compounds in this family are being explored for next-generation lithium-ion battery cathodes, solid-state electrolytes, and photocatalytic or photovoltaic devices where multi-metal synergy can enhance performance beyond single-metal oxide systems.
