Abstract

Abstract:

With the rapid development of battery-powered vehicles and electronic products in recent years, there has been a dramatic increase in the global demand for lithium. Therefore, the development and use of lithium resources has also attracted increasing attention. Because there is a large amount of lithium in brine, the selective extraction of lithium from that resource has become the focus of intensive research in recent years. There are many techniques for extracting lithium from salt lakes. Among these, electrochemical lithium extraction has attracted considerable attention because it is green, safe, highly efficient, and saves energy. Herein, recent research into lithium extraction by electrochemical methods—both domestically and abroad—is reviewed. Such research includes the development of working electrodes and counter electrodes, and the construction of various electrochemical lithium extraction systems. In addition, suggestions and prospects are given for the future development direction of electrochemical lithium extraction.

Key words: brines, extracting lithium, electrochemistry, electrolytes, selectivity
