Li4Mn5Cu3O16

Li₄Mn₅Cu₃O₁₆ is a complex mixed-metal oxide ceramic compound containing lithium, manganese, and copper oxides, typically investigated as a functional ceramic material in energy storage and electrochemistry research. This compound belongs to the family of lithium-manganese oxides with copper doping, which are explored primarily for cathode materials in advanced lithium-ion batteries and solid-state energy storage systems where high energy density and ionic conductivity are required. The copper incorporation modifies the electronic structure and electrochemical properties compared to undoped lithium-manganese oxides, making it of interest to researchers developing next-generation battery chemistries, though it remains largely in the experimental phase for commercial applications.
