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 chemicals used in ceramics and glass manufacturing, improving thermal shock resistance and lowering melting temperatures. In electrochemical applications, it functions as an electrolyte due to its ionic conductivity. Additionally, lithium sulfate solution finds use in air purification systems, where it helps absorb carbon dioxide. Its role in pharmaceutical research includes studies related to mood-stabilizing agents, although it is not administered directly in solution form for medical treatment.
