Used primarily in the treatment of bipolar disorder as a mood stabilizer, helping to control manic and depressive episodes. It is also employed in the manufacturing of lithium-ion batteries, where it serves as a precursor material for cathode production. Widely utilized in the glass and ceramic industry to reduce melting temperature and improve thermal shock resistance. Plays a role in aluminum production by enhancing the efficiency of electrolytic processes. Additionally, used in air purification systems to remove carbon dioxide, especially in confined environments like spacecraft and submarines.
