锰系锂离子筛的制备及成型方式研究进展

Research Progress on Preparation and Formating Method of Manganese Series Lithium Ion Sieve

近年来,随着科学技术进步和锂离子电池的大规模应用,市场对锂的需求快速增长。由于固体矿产锂资源有限,锂提取技术的重点已转移到盐湖卤水资源中,因此研究盐湖提锂技术具有重要价值。在现有的各种锂提取技术中,吸附法因其制备工艺简单,成为从盐湖卤水中回收锂的最有效、最环保的方法之一。而基于锂离子筛的吸附法因其吸附选择性高、再生性能好、低能耗和环保等优点被认为是最有前途的提锂方法。文章综述了锰系锂离子筛的结构特点和制备方法等该领域的最新研究进展,同时还着重讨论了锰系锂离子筛的成型技术和相关研究进展,并对离子筛工业应用中存在的不足进行了总结和展望。

Recently,along with the rapid development of science and technology,the demand of lithium resources has grown rapidly due to the large-scale application of lithium ion batteries.However,the traditional mineral lithium is limited..The focus of lithium extraction technology has shifted to lithium resources form salt lake brine.Therefore,it is of significant to study lithium extraction technology in salt lake.Among various lithium extraction technologies,adsorption has become one of the most effective and environmental friendly methods for lithium recovery from salt lake brine due to its simple process.The adsorption method based on lithium ion sieve has been recognized as the most promising method for lithium extraction due to its adsorption selectivity,high regeneration performance,low energy consumption and environmental protection.In this paper,systematically reviews the structural characteristics of manganese lithium ion sieve and preparation methods.Besides,the formation technology and related research progress of manganese series lithium ion sieve are discussed emphatically,and the shortcomings of industrial application of ion sieve are summarized and prospected.
