摘要：
As the use of lithium-ion batteries in electric vehicles, portable electronic devices, power tools, and grid energy storage continues to increase, the demand for lithium resources is growing rapidly. In China, over 71% of lithium resources are stored in salt lakes, which are abundant in the Qinghai-Tibet Plateau. Among them, salt lakes in Qinghai province generally have the characteristics of high ratio of magnesium to lithium and low lithium content. Lithium extraction from high Mg/Li ratio salt lakes is a great challenge worldwide. This review focuses on the latest progress of Mg/Li separation and lithium extraction technologies from salt lake brine with high Mg/Li ratio. We comprehensively analyzed the features and applications in terms of principles, characteristics and performance of each method including extraction, adsorption, reaction/separation coupling technology, membrane and electrochemical method. The adsorption method is more suitable for high Mg/Li brine. The extraction method can be used for brine with a lower lithium concentration. The emerging new reaction-coupled separation technology can achieve high-efficiency lithium extraction and comprehensive utilization of magnesium and lithium resources. The membrane methods like nanofiltration, electrodialysis and bipolar membranes have the advantages of lower energy consumption and modularity. The electrochemical method has the simple equipment, but the system needs to be optimized yet. The extraction of lithium from salt lakes requires to increase the total yield, to improve the comprehensive utilization of related resources, to develop high-valued lithium products, and to strengthen the engineering technology. Finally, the goal is to utilize salt lake resources more efficiently, comprehensively and sustainably. © 2021, Editorial Board of CIESC Journal. All right reserved.
