Li1 Cu1 P2 O6

Lithium copper phosphate (Li₁Cu₁P₂O₆) is an inorganic semiconductor compound belonging to the phosphate family, combining lithium, copper, and phosphorus oxide in a crystalline structure. This is a research-phase material primarily investigated for solid-state battery applications and ion-conductive ceramics, where the lithium content enables ionic transport while the copper provides electronic properties. The material represents an emerging class of hybrid ionic-electronic conductors of interest to battery developers seeking alternatives to traditional liquid electrolytes, though it remains largely in academic study rather than widespread industrial production.
