摘　　要：随着新能源行业在世界范围内的快速发展,金属锂因其能量密度高等优势被广泛应用,从蕴含大量锂资源的盐湖卤水中提锂是获取锂资源的重要方向。盐湖提锂的方法主要有碳化法、沉淀法、离子筛吸附法、电化学辅助法等。离子筛吸附法适合从浓度低的液相中选择性回收锂,其中钛系锂离子筛因其稳定性强、吸附容量大而成为吸附法的研究热点。本文以钛系锂离子筛技术为立足点,对全球锂资源分布现状、钛系锂离子筛提锂机理进行了分析,综述了目前钛氧化物锂离子筛的合成方法、成型方法、现存的问题等,为后续开发新型钛系锂离子筛,提高饱和吸附容量等方面提供参考。With the rapid development of the new energy industry,lithium is widely used because of its high energy density,extracting lithium from salt lake brine is an important way to obtain lithium resources.The main methods of extracting lithium from salt lake brine are carbonization,precipitation,ion-sieve adsorption,and electrochemical method.Ion sieve adsorption method is suitable for selective recovery of lithium from low concentration liquid phase.Titanium-based lithium ion sieve has become a research hotspot because of its strong stability and large adsorption capacity.Based on the titanium-based lithium ion sieve technology,this paper analyzes the global lithium resource distribution and the lithium extraction mechanism of titanium-based lithium ion sieve,and summarizes the synthesis methods,molding methods and existing problems of titanium-based lithium ion sieve,so as to provide reference for the subsequent development of new titanium lithium ion sieve and the improvement of saturated adsorption capacity.
