· Li2 Cu2 O2

Li₂Cu₂O₂ is a mixed-valence lithium copper oxide semiconductor compound that combines copper redox chemistry with lithium-ion conductivity, placing it in the family of layered oxide materials explored for advanced energy and electronic applications. This compound is primarily studied in research contexts for potential use in lithium-ion battery cathodes, solid-state electrolytes, and oxide electronics where the interplay between lithium mobility and copper d-orbital states offers tunable electronic properties. Its relevance lies in the ability to engineer materials with simultaneous ionic conductivity and electronic functionality, making it a candidate where conventional single-purpose oxides fall short, though it remains largely in the development phase with limited commercial deployment compared to established lithium metal oxides.
