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.
