Used as a desiccant for drying gases due to its strong hygroscopic nature. Employed in the production of lithium metal through electrolysis of molten mixtures and other lithium compounds for batteries and ceramics. Serves as a catalyst in organic synthesis, particularly in carbon-carbon bond formation reactions. Utilized in air purification systems to control humidity. Found in some brazing and welding fluxes to improve metal surface wetting. Applied in research laboratories as an electrolyte in electrochemical studies and battery development, as well as for separating biomolecules and studying solution equilibria due to its high solubility in water and effects on biological molecular structures. Also used in the textile industry for fiber spinning processes involving synthetic polymers.
