【Abstract】 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.更多还原
