Purification of LiHCO3

RESOURCES

Lithium (Li), an exceptional cathode material used in rechargeable batteries, is an essential element in modern energy production and storage devices. Extraction of lithium by processing minerals, brine, or sea water produces technical-grade Li2CO3. To upgrade the purity to electrochemical grade, there are several purification processes. Diana will show the carbonation process, during which the technical-grade Li2CO3 is subjected to carbonation with gaseous CO2 at elevated temperature and pressure to solubilize the lithium as LiHCO3. LiHCO3 is then heated at 90 ⁰C to precipitate lithium as Li2CO3 with 99.95% purity. The released CO2 is recycled for reuse
