Lithium extraction from salt lake achieves a key technological breakthrough

Against the background of the booming development of new energy worldwide, the demand for lithium resources represented by new energy electric vehicles and clean energy storage is increasing. Recently, Qinghai salt lake has made a breakthrough in the key technology of lithium resource extraction and separation, attracting attention from the energy industry. The research team of Li Lijuan from Qinghai salt lake institute of Chinese academy of sciences successfully overcame the bottleneck of efficient separation of lithium, sodium and potassium ions in the lithium brine. Compared with similar technologies at home and abroad, this technology is the only solution that simultaneously meets the four major goals of "economic feasibility, efficient recovery, clean production, and high-quality products". It provides key technical support for the high-quality development of China's salt lake lithium industry. Expert evaluation shows that this technology has reached the international leading level, and its industrial application is expected to provide important support for the efficient recovery and high value utilization of salt lake lithium resources throughout the whole process.
