摘　　要：介绍了作为锂离子筛前体的尖晶石型锂锰氧化物的结构与合成方法,指出固相配位反应法和水热合成法极具发展前景。详细论述了锂离子筛的制备、存在的问题、应用及相关研究,指出复合机理的相对合理性。最后提出开发粒(膜)状锂离子筛、进行规模化提锂工艺研究的必要性和重要意义。Spinel lithium manganese oxide as the precursor of lithium ionic sieve is presented with respect to its structure and synthesis method, and the solid-state coordination reaction method and hydrothermal method are considered as promising ways of synthesis. The preparation and application of lithium ionic sieve and the development of adsorption/desorption mechanism are introduced, and the complex theory is found more reasonable. Finally, the necessary of making granular or membrane-type lithium ionic sieve and developing large-scale technology of extracting lithium is emphasized.
