· Li4 Fe2 Cu2 O8

Li₄Fe₂Cu₂O₈ is a mixed-metal oxide semiconductor compound containing lithium, iron, and copper cations in a crystalline structure. This material belongs to the family of transition-metal lithium oxides, which are primarily of research interest for energy storage and electrochemical applications rather than mature commercial use. The compound's potential relevance lies in lithium-ion battery development, solid-state electrolytes, and catalytic applications, where the synergistic effects of multiple transition metals (Fe and Cu) may offer advantages in ionic conductivity, electrochemical stability, or catalytic activity compared to single-metal alternatives.
