Li3 In2

Li₃In₂ is an intermetallic compound in the lithium-indium system, a ternary phase that combines a highly reactive alkali metal (lithium) with a post-transition metal (indium). This material exists primarily as a research compound rather than a commercial engineering material, and belongs to the broader family of lithium intermetallics being investigated for energy storage, optoelectronic, and solid-state ionic conductor applications. Interest in Li₃In₂ stems from lithium's role in advanced battery chemistries and the potential for tailored ionic conductivity or electrochemical properties when paired with indium, though the compound remains largely exploratory and has not achieved widespread industrial adoption.
