Used as a raw material in the production of lithium-ion battery cathodes, particularly in lithium iron phosphate (LFP) batteries for electric vehicles and large energy storage systems, due to its thermal stability and safety performance. It also serves as a precursor in the synthesis of other lithium-containing compounds for electrochemical applications. Additionally, it finds use in some ceramic and glass formulations to improve heat resistance, durability, and chemical stability. In limited cases, it is employed in pharmaceuticals as a source of lithium in controlled-release formulations.
