Aluminum Iodide is the simple compound formed when Aluminum reacts with iodine and is a white or yellow colour in nature. Aluminum Iodide is a strong Lewis base which means it contains an empty orbital capable of accepting an electron pair from a Lewis base to form a Lewis product. It used to break the chemical bond between compounds like C-O and N-O. Aluminum Iodide is used as an additive for electrolytes in lithium-ion batteries.
