Used as a desiccant for drying gases due to its strong hygroscopic nature. Employed in air conditioning systems to control humidity. Serves as an electrolyte in certain types of batteries and electrochemical devices, including the production of lithium metal through electrolysis processes. Utilized in the pharmaceutical industry for the synthesis of lithium-based medications. Applied in research laboratories as a reagent for DNA and RNA isolation due to its ability to precipitate nucleic acids, and in bacterial transformation to facilitate the uptake of foreign DNA by making cells competent. Also used in humidity sensors and relative humidity measurement devices.
