Li4 Mn4 Cu2 O12

Li₄Mn₄Cu₂O₁₂ is a mixed-metal oxide ceramic compound containing lithium, manganese, and copper in a layered or spinel-related crystal structure. This is primarily a research material investigated for energy storage and electrochemical applications, particularly as a cathode material or electrode additive in lithium-ion batteries and related electrochemical devices. The compound is notable for combining multiple redox-active transition metals (Mn and Cu) with lithium, offering potential advantages in capacity, cycling stability, and cost compared to single-transition-metal oxides, though it remains largely in the experimental phase without widespread commercial deployment.
