Used as a precursor in the production of lithium-based greases, which are valued for their high-temperature stability, water resistance, and oxidation resistance, making them ideal for automotive and industrial lubrication. Plays a key role in the recovery of carbon dioxide in closed environments such as spacecraft and submarines, where it reacts with CO₂ to form lithium carbonate. Employed in the manufacture of lithium-ion batteries, contributing to the production of cathode materials such as lithium cobalt oxide and electrolytes. Utilized in the production of plastics and synthetic rubber to adjust pH levels. Also used in the synthesis of other lithium compounds for ceramics, glass, air purification systems, electronics, and pharmaceuticals.
