Hydrothermal synthesis and adsorption behavior of H₄Ti₅O₁₂ nanorods along [100] as lithium ion-sieves.

ABSTRACT: The adsorption method is a promising route to recover Li⁺ from waste lithium batteries and lithium-containing brines. To achieve this goal, it is vital to synthesize a stable and high adsorption capacity adsorbent. In this work, Li₄Ti₅O₁₂ nanorods are prepared by two hydrothermal processes followed by a calcination process. Then the prepared Li₄Ti₅O₁₂ nanorods are treated with different HCl concentrations to obtain a H₄Ti₅O₁₂ adsorbent with 5 μm length along the [100] direction. The maximum amount of extracted lithium can reach 90% and the extracted titanium only 2.5%. The batch adsorption experiments indicate that the H₄Ti₅O₁₂ nanorod maximum adsor
