Used as a precursor in the synthesis of lithium-ion battery cathode materials, particularly in lithium iron phosphate (LFP) batteries, due to its ability to provide a stable lithium source with good thermal stability. It serves as a key raw material in solid-state electrolytes and lithium conductive ceramics, enhancing ion transport in energy storage devices. Also employed in specialty glasses and ceramics requiring high heat resistance and low thermal expansion. Its buffering properties make it suitable in certain chemical processing applications where pH control is needed under high-temperature conditions.
