Used in the production of lithium-ion batteries, particularly in specialty electrolytes where stable ionic conductivity is required. It serves as a lithium source in ceramic and glass manufacturing, improving thermal shock resistance and lowering melting temperatures. Employed in air purification systems to absorb carbon dioxide and moisture due to its hygroscopic nature. Also utilized in some pharmaceutical formulations and as a component in certain electrochemical sensors. Its ability to influence cell signaling pathways makes it relevant in research settings for studying neurological disorders, though this application is primarily experimental.
