Zusammenfassung:	A lithium ion adsorbent and a method for preparing same are disclosed. The lithium ion adsorbent includes a material having a chemical formula of LiCl·2Al(OH)3nH2O, where n is an integer from 1 to 3. The method includes: mixing a lithium salt solution and a meta-aluminate solution, and performing a first stirring, a first aging and a first filtration to obtain a precursor; mixing the precursor with an acid and controlling the amount of the acid added to obtain a mixture with a pH value of 6.0-7.0, and performing a second stirring, a second aging and a second filtration to obtain a residue obtained from the second filtration; and treating the residue obtained from the second filtration by 1 to 3 cycles of pre-desorption and filtration.
