Used primarily in the production of lithium greases, which are valued for their high-temperature stability and water resistance, making them ideal for automotive and industrial lubrication. Plays a key role in the manufacture of lithium-ion batteries, particularly in the processing of cathode materials. Employed in air purification systems, especially in confined environments like spacecraft and submarines, where it effectively absorbs carbon dioxide from the air. Also utilized in the synthesis of other lithium compounds and in certain types of cement and ceramics to modify setting properties and improve durability.
