| 摘 要： | 锂资源是国家重要战略资源，其广泛应用于新能源汽车、电子产品、储能等诸多领域。中国锂资源储量丰富，其中盐湖卤水锂资源主要分布在青海与西藏地区，但受制于盐湖卤水自身品位较低、锂盐提取效率低下以及生产能力有限等因素，未能得到有效开发，使得对国外锂产品产生了严重的依赖。因此，为保障中国锂资源持续安全供应，着力突破盐湖提锂技术，探索出更为绿色、高效且低成本的提取技术对盐湖卤水锂资源的利用具有重要意义。系统地介绍了盐湖锂资源概况、盐湖卤水特点以及锂资源高效分离提取的最新研究进展，最后对锂资源分离提取技术的研究重点做出了展望。

| Abstract: | Lithium resources are important national strategic resources,which are widely used in many fields such as new energy vehicles,electronic products,and energy storage.China is rich in lithium resources.Among them,salt lake brine lithium resources are mainly distributed in Qinghai and Tibet.However,due to factors such as the low grade of salt lake brine itself,low extraction efficiency of lithium salt and limited production capacity,it has not been effectively developed,resulting in a serious dependence on foreign lithium products.Therefore,in order to ensure the continuous and safe supply of lithium resources in China,it is of great significance to break through the lithium extraction technology from salt lakes and explore more green,efficient and low-cost extraction technologies for the utilization of lithium resources in salt lake brines.The general situation of lithium resources in salt lakes,the characteristics of salt lake brine,and the latest research progress of efficient separation and extraction of lithium resources were systematically introduced.Finally,the research focus of lithium resources separation and extraction technology was prospected. |
