摘要：
Lithium and its compounds are important strategic resources for the national economy and national defense construction. It has important applications in the fields of energy storage batteries, fine chemicals, and atomic energy thermonuclear fusion. China is a major consumer and producer of lithium resources, but our lithium consumption is more than 70% dependent on foreign sources. At the same time, lithium resources in China are mainly stored in salt lake brines in the western region. The problems of low lithium concentration and high magnesium-to-lithium ratio have increased the difficulties of lithium extraction. In view of the existing problems of lithium extraction from salt lakes in China, this article systematically summarizes the traditional methods for extracting lithium resources from salt lakes, and focuses on the important progress of new membrane separation materials and membrane separation processes in the efficient extraction of lithium from salt lake brines, especially the latest achievements made by Chinese researchers. © 2022, Editorial Board of CIESC Journal.
