摘要
锂作为新能源领域的战略性金属,其高效开发对全球能源转型至关重要。盐湖卤水占全球锂资源储量的60%~65%,但高镁锂比导致的分离难题使传统提锂方法面临选择性差、能耗高或环境污染等问题。钛系锂离子筛凭借高锂选择性及钛氧骨架稳定性成为盐湖提锂的研究热门。围绕钛系离子筛材料在盐湖提锂中的研究进展,对全球液态锂资源的开发技术、钛系锂离子筛的合成方法、提锂机制及掺杂改性的最新成果进行了分析评述,在指出现有问题的同时,对未来发展进行了合理展望,可以为钛系锂离子筛的材料设计、合成工艺、理论机制和强化改性等提供参考。
Lithium is a strategic metal in the field of new energy,and its efficient development is crucial to global energy transformation.Salt lake brine accounts for 60%~65% of the world's lithium resource reserves.However,the separation problem caused by high ratio of Mg to Li makes the traditional lithium extraction method face problems such as poor selectivity,high energy consumption or environmental pollution.Titanium-based lithium ion sieve has become a hot research topic in lithium extraction from salt lakes due to its high lithium selectivity and stability of titanium-oxygen skeleton.The development technology of global liquid lithium resources,the synthesis method of titanium-based lithium ion sieve,the mechanism of lithium extraction and the latest achievements of doping modification are analyzed and reviewed focusing on the research progress of titanium-based ion sieve materials in lithium extraction from salt lakes.The existing problems are pointed out and the future development is prospected,which provide reference for the material design,synthesis process,theoretical mechanism and strengthening modification of titanium-based lithium ion sieves.
