Nickel iodide (NiI₂) is an inorganic compound that exists primarily as a layered crystalline material, belonging to the halide family of transition metal compounds. While not widely used in conventional structural engineering, NiI₂ is of significant interest in materials research for layered material applications, particularly as a precursor or component in two-dimensional material synthesis and as a model system for studying layered crystal physics. The material's weak interlayer bonding and potential for exfoliation make it relevant to emerging technologies in nanoelectronics, energy storage, and catalysis, though current applications remain largely in the research and development phase rather than mature industrial production.
