电化学提锂体系及其电极材料的研究进展

Research progress of electrochemical lithium extraction systems and electrode materials

近年来,随着新能源汽车和电子类产品的快速发展,锂及其化合物得到广泛应用,使得全球对锂资源需求量剧增,锂资源的开发利用也越来越受重视。因盐湖卤水中含有大量锂资源,近年来盐湖卤水选择性提锂成为研究热点和主要途径。盐湖提锂的多种技术方法中,电化学提锂具有高效节能、安全环保等优势而备受关注。本文对近年来国内外电化学方法提锂的研究工作进行了综述,包括工作电极和对电极的研究进展以及不同电化学提锂体系的构建等。另外,还对电化学方法提锂未来的发展方向给出了建议和展望。

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.
