Lithium sulfate solution is widely used in the production of lithium-ion batteries, where it serves as a precursor for cathode materials. It is also employed in the synthesis of other lithium-based compounds used in ceramics, glass, and aluminum processing. In electrochemical applications, it functions as an electrolyte due to its ionic conductivity. The solution is utilized in air purification systems to absorb carbon dioxide, especially in confined environments like spacecraft and submarines. Additionally, it finds use in some pharmaceutical formulations and psychiatric treatments, as lithium compounds are effective in managing mood disorders. Its high solubility and stability in aqueous systems make it suitable for various industrial and research applications requiring a reliable lithium source.
