Cobalt iodide (CoI₂) is an intermetallic compound combining cobalt and iodine, belonging to the transition metal halide family. While not a mainstream structural material in conventional engineering, CoI₂ is of significant interest in materials research for layered crystal structures and two-dimensional material applications, particularly as a candidate for exfoliation into thin-film devices. Its notable low exfoliation energy makes it attractive for emerging technologies in electronics, photonics, and energy storage where atomically thin materials are engineered for enhanced properties.
