| Abstract |
An Li-Al layered double hydroxide (LDH) was synthesized via a mechanochemical route to adsorb lithium cations by using lithium salt (Li2CO3, LiCl, LiOH). Mechanochemical synthesis of Li-Al LDH was carried out with a mixture of gibbsite Al(OH)3 and lithium salts for 12 hours by ball milling operation. As a result, LiCl and LiOH salts were absorbed in Al(OH)3 rather than Li2CO3. The average size of as-synthesized Li-Al LDH nanosheets were variable from 100nm to 10㎛ on the different synthetic conditions. The solubility of the lithium salts plays an important role on the lithium ion reaction with Al(OH)3 lattice. The as-prepared samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetry (TG) and differential scanning calorimetry (DSC). |
