| Abstract |
An LiAl2-layered double hydroxide(LDH) was synthesized on an aluminum foil in an aqueous solution of LiCl by urea hydrolysis to adsorb lithium cations. As-adsorbed lithium cations in LiAl2-LDH were simply extracted in a distilled water at 70~90℃. This work presents a method for directly growing oriented LiAl2-LDH films on aluminum foil. The concentrations of urea and LiCl were controlled to find the optimal conditions for synthesis of LiAl2-LDH. The concentration of LiCl is a critical factor rather than the concentration of urea in the synthesis of LDH. Concentration of as-adsorbed lithium cations in LiAl2-LDH was determined by inductively coupled plasma(ICP), thermogravimetric analysis(TGA) and lithium ion selective electrode(ISE). |
