Abstract:

Under the rapid development of the new energy industry,the development of lithium brine resources has become an important connotation of the development of strategic emerging industries worldwide.Membrane separation technology has become the mainstream process for lithium extraction from salt lake brine with high magnesium lithium ratio in China,due to its excellent separation performance of monovalent/divalent ions,good environmental protection and economy.The separation mechanism,research progress and future development of membrane separation technology in brine system were summarized and analyzed.The continuous research and development of new high-performance lithium ion separation membranes would certainly accelerate the development of lithium resources in brine in China.

Key words: lithium extraction from salt lake brine, nanofiltration membrane, electrodialysis membrane, ion imprinted membrane, antifouling membrane
