Anhydrous lithium iodide has broad application prospects in lithium batteries. The number of manufacturing companies in my country is still relatively small.

Anhydrous lithium iodide is one of the lithium compounds with the molecular formula LiI. It appears as a white crystalline powder and is easily soluble in water, ethanol, and acetone. It is corrosive to glass and ceramics when melted. Anhydrous lithium iodide has good solubility, ionic conductivity, high selectivity, chemical stability, etc., and has broad application prospects in the fields of medicine, batteries, chemicals, catalysts, optoelectronic devices, etc.

Specifically, in the battery field, anhydrous lithium iodide is mainly used in lithium battery electrolyte production scenarios, playing a role in improving lithium-ion battery performance and improving battery cycle stability. Currently, it is prepared using anhydrous lithium iodide. Lithium-ion batteries have been widely used in medical, electronic and other fields; in the field of catalysts, anhydrous lithium iodide can be used as a reaction catalyst in organic synthesis reactions (coupling reactions, oxidation reactions, etc.), playing a role in promoting the stability of reactions. ; In the field of optoelectronics, anhydrous lithium iodide can be used in device manufacturing scenarios such as photoelectric sensors, photoconductors, photoelectric and color-changing films; in the medical field, anhydrous lithium iodide can be used in the synthesis of dopamine drugs, L-ribonucleosides and other drugs Scenes.

According to the “2023-2028 Anhydrous Lithium Iodide Industry Market In-depth Research and Investment Prospects Forecast Analysis Report” released by the Industrial Research Center It shows that anhydrous lithium iodide has a wide range of application fields, among which the wide application of lithium batteries is the main driving force for the rapid development of the anhydrous lithium iodide market. In 2022, the domestic lithium battery market shipments will exceed 650GWh, a year-on-year increase of more than 100%. Against this background, my country’s anhydrous lithium iodide market size will be approximately 82.4 million yuan in 2022, a year-on-year increase of approximately 16%.

From the production side, the current methods for producing anhydrous lithium iodide mainly include acetone method, hydrazine method, H2S reduction method, neutralization method, liquid ammonia method, organic solvent method, etc. Among them, the neutralization method is the mainstream production method of anhydrous lithium iodide. It refers to using lithium hydroxide or lithium carbonate and hydriodic acid as raw materials to generate lithium iodide containing crystal water through chemical reaction, and then through vacuum distillation and electrolysis. A method to generate anhydrous lithium iodide without crystal water through processes such as chemical electrolysis.

As the world’s largest chemical country, my country’s current domestic upstream raw materials for anhydrous lithium iodide can be obtained through market-based procurement. The supply is relatively sufficient and the industry has a good foundation for development. However, due to technical limitations, the number of domestic companies with anhydrous lithium iodide production capacity is currently relatively small. Only Hubei Baijiere New Materials, Taian Hanwei Group, Xinjiang Junqiang Technology Development, Xinjiang Nonferrous Metals Group, and Jiangxi Ganfeng Lithium Industrial Group, Shanghai Xinman Sensing Technology and a few other companies.

Industry analysts said that anhydrous lithium iodide is an important type of lithium compound that can be widely used In medical, chemical, optoelectronic, battery and other fields. Among them, lithium batteries are the main application field of anhydrous lithium iodide. Benefiting from the rapid development of the lithium battery industry, the demand for anhydrous lithium iodide continues to increase. Due to technical limitations, the number of enterprises in my country’s anhydrous lithium iodide production field is still relatively small, and there is still considerable room for growth in the industry in the future.
