Chemical chemical compound

Lithium iodide, or LiI, is a chemical compound of lithium and iodine. When exposed to air, it becomes yellow in color, due to the oxidation of iodide to iodine.^[2] Information technology crystallizes in the NaCl motif.^[3] It tin participate in diverse hydrates.^[four]

Applications [edit]

Lithium iodide is used as a solid-state electrolyte for high-temperature batteries. Information technology is too the standard electrolyte in artificial pacemakers^[6] due to the long bicycle life it enables.^[7] The solid is used as a phosphor for neutron detection.^[viii] It is also used, in a complex with Iodine, in the electrolyte of dye-sensitized solar cells.

In organic synthesis, LiI is useful for cleaving C-O bonds. For example, it can be used to catechumen methyl esters to carboxylic acids:^[9]

RCO₂CH_iii + LiI → RCO_twoLi + CH₃I

Similar reactions utilize to epoxides and aziridines.

Lithium iodide was used as a radiocontrast agent for CT scans. Its use was discontinued due to renal toxicity. Inorganic iodine solutions suffered from hyperosmolarity and high viscosities. Current iodinated contrast agents are organoiodine compounds.^[x]
