More than 70％of the global lithium ores exist in the"salt lake"type,so it is important to comprehensively review the lithium extraction technology from salt lake.The article analyzes the global development trend of lithium extraction from salt lake based on the multi-source literature such as fund projects(exploratory research),conference papers(frontier research),scientific papers(basic research),and patent literature(applied R&D),and the knowledge correlation based on the representations of different links of the innovation value chain.Through the fusion and correlation digging on multi-source literature,the evolution process of scientific knowledge that drives technological progress is described,the evolutionary trajectory of cutting-edge technology's emergence,development,and mutation is tracked,and the future development direction of the key industries and technologies for lithium extraction from salt lake is evaluated.Analysis results show that the salt lake resources extraction technologies mainly concentrate in the technical directions such as adsorption,membrane separation,extraction,etc.In addition,certain R&D layout focuses on precipitation,electrochemical,dialysis,crystallization,and ion exchange methods.In addition,the technology integration and various technical process combination are obvious characteristics.
