1. A method for preparing a lithium adsorbent, comprising the steps of:
uniformly mixing raw materials comprising a lithium compound, an aluminum compound, a pore-forming agent, a hydrophilic binder and water, and carrying out a reaction at a temperature ranging from 60° C. to 100° C. for 2 h to 4 h so that the lithium compound reacts with the aluminum compound to form an aluminum-based lithium adsorbent active material; wherein a ratio of a total weight of the lithium compound, the aluminum compound and the hydrophilic binder to a weight of the pore-forming agent is 100:(0.6 to 20); and
curing the hydrophilic binder in the raw material mixture, and performing granulating and drying to obtain the lithium adsorbent.
