Li₂I₂ is an inorganic ionic ceramic compound composed of lithium and iodine, belonging to the halide ceramic family. This material is primarily of research and developmental interest for solid-state battery applications, where it functions as a component in lithium-ion conducting electrolytes and related electrochemical systems. As an experimental compound rather than an established industrial material, Li₂I₂ is notable for its potential to enable higher energy density and improved thermal stability compared to conventional liquid electrolyte systems, though engineering adoption remains limited to laboratory-scale prototypes and advanced battery development programs.
