摘要:

随着新能源电动汽车、储能产业的快速发展,确保锂资源的供给成为热点话题。锰系锂离子筛因其有对锂离子的高选择性、高吸附量、低成本等优点,在盐湖提锂方面已成为最具发展潜力的吸附剂材料之一,然而其在循环吸、脱附过程中,锰的溶损以及Jahn-Teller效应等问题会影响离子筛结构的稳定性,使吸附剂的吸附性能降低。近年来,围绕吸附性能提升,从制备方法方面进行改良的研究工作很多,可通过不同的制备方法调控锂离子筛的结构和形态。针对其存在的问题,总结了可以改善其性能的方法,包括掺杂、表面包覆以及造粒和成膜等,并在此基础上对改性锂离子筛材料在工业应用方面的发展方向进行展望,制备出高数量级循环下稳定的锂离子筛材料是未来的主要发展方向。

Abstract:

With the rapid development of new energy electric vehicles and energy storage industry,ensuring the supply of lithi-um resources has become a hot topic.Manganese based lithium ion sieve has become one of the most potential adsorbents for lithium extraction from salt lakes due to its high selectivity,high adsorption capacity and low cost.However,in the process of cyclic adsorption and desorption,the dissolution of manganese and Jahn-teller effect will affect the structural stability of the ion sieve and reduce the adsorption performance of the adsorbent.In recent years,for the improvement of adsorption perfor-mance,a lot of research work has been carried out on the improvement of preparation methods.The structure and morphology of lithium ion sieve can be controlled by different preparation methods.In view of the existing problems,the methods to im-prove the performance of the adsorbent were summarized,including doping,surface coating,granulation and film-forming.On this basis,the development direction of modified lithium-ion sieve materials in industrial application was prospected.The main development direction in the future was to prepare lithium ion sieve materials with high order of magnitude and stable cycle.

Key words: new energy, lithium ion-sieve, adsorbent, dissolving, modification
