摘　　要：目前全球动力、储能需求呈爆发式增长,全球锂电市场将迈入TWh时代,锂行业无疑正身处“超级周期”之中,但非线性加速增长的需求以及价格的大幅上行,也给新能源产业的中下游带来了显著的“资源焦虑”。因此,开发针对不同类型盐湖的提锂技术具有重要意义。本文根据锂资源的赋存状态,对卤水提锂技术进行了综述,系统总结和对比了各方法的优缺点。经过多年的探索,目前盐湖提锂技术百花齐放,太阳池法、化学沉淀法、萃取法、煅烧法、吸附法、膜分离法等都有工业应用,电化学法等新技术也逐渐涌现。In view of the explosive growth of global energy storage demand,the global lithium market would enter the TWh era.The lithium industry was undoubtedly in the super cycle,with non-linear accelerated demand growth and a significant upward trend,but it had also brought significant"resource anxiety"to the new energy industry in the middle and lower reaches.Therefore,it was of great importance to find lithium extraction technologies for different types of salt lakes.In this paper,the lithium extraction technology of brine was reviewed according to the status of lithium resources,and the advantages and disadvantages of various methods were systematically summarized and compared.After years of exploration,the current technology of lithium extraction from salt lakes was flourished,with industrial applications of solar cell method,chemical precipitation method,extraction method,calcination method,adsorption method,membrane separation method,etc.,and new technologies such as electrochemical method were also gradually emerging.
