LiCu

LiCu is an intermetallic compound combining lithium and copper, representing an experimental material within the broader family of lithium-based alloys and copper intermetallics. While not yet widely established in mainstream industrial production, this composition is of research interest for applications requiring lightweight properties combined with electrical conductivity, particularly in advanced battery systems, aerospace structures, and electronic interconnect materials where the unique combination of lithium's low density and copper's excellent electrical and thermal properties could offer design advantages.
