· JVASP-42149· Li7CuO4

Li7CuO4 is a lithium copper oxide ceramic compound belonging to the family of lithium-based mixed-metal oxides. This material is primarily of research and development interest rather than widespread industrial use, with investigations focused on its potential as a lithium-ion conductor and electrochemical application in solid-state battery systems and ionic transport membranes. Engineers and materials scientists studying advanced energy storage and solid electrolyte technologies may evaluate this compound for its structural and ionic properties, though it remains largely in the experimental phase compared to more established ceramic electrolyte alternatives.
