Used primarily in the treatment of bipolar disorder as a mood stabilizer, helping to reduce the severity and frequency of manic episodes. It is also employed in the management of recurrent depression when other treatments are ineffective. In industry, it serves as a precursor in the production of specialty glasses and ceramics, where it lowers melting temperatures and improves thermal shock resistance. Additionally, lithium carbonate is a key raw material in manufacturing cathode materials for lithium-ion batteries, contributing to energy storage technologies in electronics and electric vehicles. Its use in aluminum production enhances the efficiency of electrolytic processes.
