· JVASP-49798· Li2CuPO4

Li2CuPO4 is an inorganic ceramic compound combining lithium, copper, and phosphate phases, belonging to the family of phosphate ceramics with potential electrochemical functionality. This is primarily a research material explored for solid-state battery applications, particularly as a cathode material or electrolyte component in lithium-ion and all-solid-state battery systems, where the copper-phosphate framework offers ionic conductivity pathways and structural stability. Engineers and materials researchers evaluate this compound for next-generation energy storage where the combination of lithium mobility and copper's redox chemistry could enable higher energy density or improved thermal stability compared to conventional layered oxide cathodes.
