Used as an electrolyte in lithium-ion batteries due to its high ionic conductivity and thermal stability. Plays a role in the treatment of bipolar disorder in pharmaceutical formulations, though less commonly than other lithium salts. Employed in ceramics and glass manufacturing to reduce thermal expansion and improve shock resistance. Also utilized in analytical chemistry as a buffering agent in X-ray fluorescence and mass spectrometry. Shows potential in solid-state battery development because of its stability in high-temperature applications.
