The most well-known lithium salt is lithium carbonate, which helps stabilize mood and reduce the frequency of manic and depressive episodes. In addition to their medical uses, lithium salts are also important in various industrial applications. They are used in the production of batteries, particularly in rechargeable lithium-ion batteries, which power many electronic devices. Their unique properties make them valuable in both healthcare and technology sectors.
