2020年12月1日 · We propose a reaction scheme to selectively separate lithium ions from an aqueous urea solution by formation of lithium aluminum layered double hydroxide (LDH) on aluminum metal foils.

2024年8月15日 · Aluminum-based adsorbents, simply prepared by eluting the lithium-aluminum layered double hydroxide precursors with deionized water, is the only industrialized adsorbents for selectively separating Li + from saline brines.

Crystal structure of lithium-aluminum double hydroxide (Li Al2 (OH)6 Cl) [126]. Li, Al, Cl, O, and H represented as purple, gray, green, red, and white, respectively. Reproduced with...

Lithium–aluminum layered double hydroxides (LDHs) selectively sorb lithium from brines, concentrating and purifying this critical element for subsequent conversion to active battery components. Lithium ion partitioning into lattice vacancies within the LDH structure is selectively enhanced with iron doping.

2023年10月6日 · Lithium aluminum layered double hydroxide chlorides (LADH-Cl) have been widely used for lithium extraction from brine. Elevation of the performances of LADH-Cl sorbents urgently requires knowledge of the composition–structure–property relationship of LADH-Cl in lithium extraction applications, but these are still unclear.

1998年11月1日 · The structure of intercalation complexes of aluminum hydroxide with lithium salts is investigated by X-ray diffractometry and by21Al,7Li, and1H NMR. The lithium ions occupy vacant...

The structure of intercalation complexes of aluminum hydroxide with lithium salts is investigated by X-ray diffractometry and by 21 Al, 7 Li, and 1 H NMR. The lithium ions occupy vacant positions in the octahedral voids of aluminum hydroxide, and all atoms of gibbsite change localization.

1993年3月1日 · Cryogenic heat capacity measurements and thermodynamic analysis of lithium aluminum layered double hydroxides (LDHs) with intercalated chloride. American Mineralogist 2022, 107 (4) , 709-715. https://doi.org/10.2138/am-2021-7935

Based on the tetrahedral coo dination of lithium, the authors of[19] suggested astructural model for the highest-symmetry alnrnlnum and lithium b nary hydroxide [LiOH. 2A](OH)3.2H20 ] (hereinafter deno by ALBH-OH) d in space group P63cm. The atomic coordinates were determined from structural crystal-optical data [20-26].

Lithium/aluminum layered double hydroxides (Li/Al-LDHs) were synthesized via a facile hydrothermal route, using lithium and aluminum chloride mixed solutions with various molar ratios (Li+/Al3+ = 2, 3, 4, 5) as precursors and urea as a precipitating agent. The …
