Lithium ion adsorbent and preparation method thereof
By inserting sulfate ions (SO42-) into the interlayer of lithium-aluminum layered double hydroxides (LiAl-LDHs), LiAl-LDH-S materials were prepared, solving the structural collapse problem caused by excessive Li+ deintercalation and intercalation, and improving the structural stability and economy of lithium-ion adsorbents.

Abstract
The invention discloses a lithium ion adsorbent and a preparation method thereof. The lithium ion adsorbent is prepared from the following raw materials: soluble aluminum salt, soluble lithium salt, soluble alkali and soluble sulfate. According to the lithium ion adsorbent prepared by the invention, the soluble sulfate is added into the preparation raw materials, so that the phenomenon of structural collapse caused by repeated elution of lithium ions is weakened, the elution inactivation resistance of the adsorbent is enhanced, and the service life of the lithium ion adsorbent is prolonged.
