· Li3 Cu4 O4

Li₃Cu₄O₄ is a mixed-valence copper-lithium oxide ceramic compound that functions as a semiconductor, belonging to the family of transition metal oxides with potential electrochemical and photocatalytic activity. This material remains largely in the research and development phase, where it is being investigated for applications in energy storage systems, photocatalysis, and advanced ceramics due to the synergistic effects of lithium and copper ions in its crystal structure. Its appeal lies in the possibility of combining lithium's electrochemical properties with copper's catalytic behavior, offering potential alternatives to conventional lithium-ion battery cathodes or catalytic materials, though practical engineering adoption is not yet widespread.
