Lithium is widely used in digital products and new energy vehicles due to its low density and low redox potential, and there are huge prospects for extracting lithium from the brines of salt lakes. In addition, it is well known that the majority of the lithium salt lake brines on Earth have been identified in high-altitude areas with harsh geographical environments. Nevertheless, there are also rich natural energy sources, such as wind and tidal energy. Therefore, it is vital to develop a novel variety of lithium-ion sieves that can utilize natural energy. It is highly exclusive and selective for lithium-ions in salt lakes to achieve low-cost and large-scale lithium extraction under natural conditions. In this paper, BaTiO 3 -LiFePO 4 (BTO-LFP) piezoelectric composite-based lithium-ion sieve materials were successfully prepared and utilized to convert kinetic energy into electrical energy, which should be used in lithium extraction from raw brines with natural energy. According to the experiments, the materials can reach adsorbing equilibrium in simulated brine after 48 h. The lithium adsorption amount is 21.5 mg/g and can also reach adsorbing equilibrium in Yi-Liping raw salt lake brines after 72 h, and the adsorption amount can also reach 21.7 mg/g which indicates that this lithium-ion sieve is specific and selective for lithium-ion. What's more surprising is that this lithium-ion sieve only uses natural kinetic energy as the driving force for lithium extraction. Therefore, this study has devised an innovative technique for extracting lithium from natural brines, which shows significant promise, for the large-scale exploration of lithium resources from salt lakes under harsh natural conditions.

Lithium has been a high-demand element with the rapid development of lithium-ion batteries. The recovery of lithium from salt lake brine via solvent extraction is considered a promising technique. In this study, the solvent extraction process in the tributyl phosphate (TBP)–FeCl3/brine system was investigated. The order of metal ions competitively combining with TBP–FeCl3 was Li+ > Na+ > K+ > Mg2+, and the compositions of main cationic extraction complexes were Li(TBP)2(H2O)2+, Na(TBP)2(H2O)4+, K(TBP)2(H2O)4+, and Mg(TBP)2(H2O)42+, respectively. The energy decomposition analysis showed that the electrostatics was the major interaction between the metal ions and the solvent (TBP and water). Compared with water, TBP bound more competitively with the metal ions. The calculated species distribution results showed that the ferric ion reacted with the chloride ion to form FeCl2+, FeCl3, and FeCl4– in high Cl– concentration brine. Co-extractant FeCl3 was found to exist in the organic phase in the form of FeCl4– upon comparing the experimental and simulated spectra. Furthermore, the length of the Fe–Cl bond increased and the charge on the iron element was distracted when the FeCln3–n complexes coordinated with the water molecules. This indicated that FeCl4– was more stable in the TBP solvent environment and it can be extracted from the aqueous phase. The results help us understand the extraction mechanism in essence and develop a high-efficiency extraction solvent for industrial lithium recovery.

In response to the increasing demand for lithium in industrial applications, efficient lithium extraction methods have become a research focus. This study presents the synthesis of porous manganese-based lithium-ion sieve adsorbent (HMn 2 O 4 ) for the selective recovery of lithium from brine. A high-temperature solid-phase method was employed to prepare a porous LiMn 2 O 4 precursor, increasing the interaction between the adsorbent and lithium-containing solutions. The results showed that porous HMn 2 O 4 achieved high adsorption rates and capacity, with the equilibrium reached in 5–30 min and lithium adsorption reaching up to 30.83 mg·g −1 . Moreover, after ten adsorption-desorption cycles, the adsorption capacity of the sample remained at 91.85 % relative to the pristine adsorbent, demonstrating excellent stability and reusability. These findings suggest that the porous HMn 2 O 4 adsorbent is a promising candidate for large-scale lithium extraction from salt lakes, providing a cost-effective and environmentally friendly solution to meet the growing demand for lithium.

Environmental boron removal and salt lake brine boron enrichment are important separation processes, which are of great significance to animal and plant health, environmental safety, and effective use of resources. Polymers are often used for boron separation due to their low cost and high performance. In this study, Tris(hydroxymethyl)methyl aminomethane (TRIS) and glucose functionalized polymer (P(GMA-co-TRIM)) were synthesized by hydrothermal method , and the polymer structure were characterized by FTIR, SEM, Mapping, XRD , XPS, PZC and TG-DSC-DTG. P(GMA-co-TRIM)-TRIS and P(GMA-co-TRIM)-Glu were used as boron adsorbents and the performance test were carried out. When the pH = 8 of boron solution, the two adsorbents have the best adsorption performance, with the adsorption capacity of 16.25 and 18.09 mg/g, respectively. The effects of initial concentration and contact time on boron adsorption were studied. Langmuir adsorption isothermal model and pseudo-second-order model were more consistent with the adsorption data, and the adsorption process was chemical adsorption . The two adsorbents have strong resistance to ion interference and cycle life, and have potential application value in environmental boron removal and boron extraction from salt lake.

It is of importance to reclaim single-salt of potash from Li + -type brines of low concentration. In this work the potassium salts KHCO 3 was efficiently separated from the lithium carbonate-type brines with the aid of CO 2 carbonation. The phase field was provided in which the precipitation of KHCO 3 occurs and single-salt of potassium can be obtained. The low concentration of [Li + ] was also successfully concentrated to a high level (8.1 g/L), and this concentration can be used as sources for Li + -salts production using pre-developed strategies, which looks forward wider applications of the lithium resources of natural brine. This state-of-art was traced via isotherm evaporation on the quaternary system of Li + –K + –CO 3 2− –H 2 O at 298.15 K in which the carbonation steps were performed by CO 2 . Metastable phase diagram was found to consist of three invariant points, seven univariant curves, and four crystallization fields corresponding to Li 2 CO 3 , KHCO 3 , potassium carbonate sesquihydrate (K 2 CO 3 ⋅ 3/2H 2 O), and a potassium carbonate and potassium bicarbonate double salt (K 2 CO 3 ⋅ 2 KHCO 3 ⋅ 1.5H 2 O). There was no crystallization field corresponding to LiHCO 3 . The pH-composition diagram and density-composition diagram were also plotted. This work was carried out in aim of extracting/separating single salts of alkali metals from carbonate-type brines of west China.

Powder Li/Al-layered double hydroxides (LDHs) of Li 2 Al 4 (CO 3 )(OH) 12 ·3H 2 O were hydrothermally synthesized in one pot with sodium alginate as a structure modifier and granulated by crosslinked sodium alginate. The powder and granulated Li/Al-LDHs lithium adsorbents were characterized by FT-IR spectroscopy, XRD, SEM, TEM, XPS, and porosity. The adsorption-desorption performance of the granulated Li/Al-LDHs adsorbents was evaluated. Adsorption isotherm , adsorption kinetics , adsorption thermodynamics were investigated. The effects of solution pH, temperature, and the electrolytes (NaCl, Na 2 SO 4 , MgCl 2 , and KCl) on lithium adsorption, and the dissolution of granulated Li/Al-LDHs adsorbents after cyclic adsorption-desorption were also investigated. The granulated Li/Al-LDHs adsorbed 14.5 mg/g of lithium from the brine of East Taigener Salt Lake with a lithium concentration of 1400 mg/L. The granulation of powder Li/Al-LDHs by crosslinked alginate greatly reduced the dissolution of powder Li/Al-LDHs. The granulated Li/Al-LDHs adsorbents prepared in this report are promising materials for Li + extraction from salt lake brines.

In order to satisfy the growing global demand for lithium, selective extraction of lithium from brine has attracted extensive attention. LiMn 2 O 4 -based electrochemical lithium recovery system is one of the best choices for commercial applications because of its high selectivity and low energy consumption. However, the low ion diffusion coefficient of lithium manganate limits the further development of electrochemical lithium recovery system. In this work, a novel porous disc-like LiMn 2 O 4 was successfully synthesized for the first time via two-step annealing manganese (II) precursors. The as-prepared LiMn 2 O 4 exhibits porous disc-like morphology, excellent crystallinity, high Li + diffusion coefficient (average 7.6 × 10 −9 cm 2 ⋅s −1 ), high cycle stability (after 30 uninterrupted extraction and release cycles, the crystal structure hardly changed) and superior rate capacity (93.5% retention from 10−120 mA⋅g − 1 ). The porous structure and disc-like morphology further promote the contact between lithium ions and electrode materials. Therefore, the assembled electrochemical lithium extraction device with LiMn 2 O 4 as positive electrode and silver as negative electrode can realize the rapid and selective extraction of lithium in simulated brine (adsorption capacity of lithium can reach 4.85 mg⋅g −1 in 1 h). The mechanism of disc-like LiMn 2 O 4 in electrochemical lithium extraction was proposed based on the analysis of electrochemical characterization and quasi in situ XRD. This novel structure may further promote the practical application of electrochemical lithium extraction from brine.

In view of the coexistence of lithium and boron in brines, in this article, the novel adsorption technology was developed for the simultaneous recovery of lithium and boron from brines based on the cooperative action of titanium-type lithium-ion sieves and N-methylglucamine boron specific resins. During the collaborative adsorption, lithium-ion sieves adsorbed Li+ ions based on the Li+/H+ ion-exchange mechanism, and the released H+ ions from lithium-ion sieves would be neutralized by the amine functional groups of the N-methylglucamine resins to enhance the Li+/H+ ion exchange. Meanwhile, the adjacent double hydroxyl functional groups of the N-methylglucamine resins formed preferentially the complexation adsorption with borate ions to recover boron from brines. The synergistic adsorption mechanism between lithium-ion sieves (home-made PVB-HTO granules) and N-methylglucamine boron specific resins (commercial D403 resins) was investigated experimentally in batch adsorbers. Furthermore, six groups of experiments were performed in the continuous mode for the simultaneous recovery of lithium and boron from the salt-lake brines with 50∼200 mg/L of Li and B contents and 50–200 of Mg/Li molar ratio, where three-stage continuous stirred–tank adsorbers containing 18 L of brine, 300 mL of PVB-HTO granules, and 600 mL of D403 resins were used for the lithium and boron recovery from brine. Then, the regeneration of the PVB-HTO granule-packed column by 0.3 M HCl solution was carried out to obtain the lithium-rich solution, and the regeneration of the D403 resin-packed column by 0.3 M HCl solution was performed to obtain the boron-rich solution. The feasibility and efficiencies of the adsorption method for the simultaneous recovery of lithium and boron from salt-lake brines will be evaluated.

Efficient separation of lithium from salt lake brine with high Na/Li ratio is of great importance for the development of new energy industry. Liquid-liquid extraction using β-diketone system was proved to be an effective approach to separate lithium from alkaline metal ions, while the separation effect of lithium to alkali earth ions needs further investigation. In this work we proposed an extraction process using HBTA/TRPO system to recovery lithium from salt lake brine with high Na/Li ratio. The conditions of saponification, extraction, eluting, stripping and regeneration process was optimized by equilibrium experiments. Through the process, lithium, calcium and magnesium were extracted to the organic phase and then stripped step by step to obtain lithium-rich solution, then the stability of the process and organic was tested by cycle experiments, the results indicated the proposed method was effective and stable. Theoretical study based on density functional theory was conducted to expound the extraction selectivity to different metal ions, and the energy change, electrostatic potential and Mulliken charge of the complexes was obtained, the calculated results suggested the stability of the complexes followed the sequence: Mg 2+ > Ca 2+ > Li + > Na + > K + , which is consistent with the experimental results. The present work may provide a novel way to efficiently recover lithium from salt lake brine with high Na/Li ratio.

Hierarchical meso- and macro-porosity increases the adsorption capacity of lithium adsorbents and the granulation of powder lithium adsorbents raises the applicability of lithium adsorbents. Granulated lithium adsorbents consisting of porous mixtures of Li-Al-LDHs (layered double hydroxide) and NH 4 Al 3 (SO 4 ) 2 (OH) 6 by crosslinking sodium alginate were successfully prepared, and adsorption-desorption performance of granulated adsorbents was evaluated. The adsorption capacity of granulated lithium adsorbents reached 9.66 mg/g (at the loading capacity of 83.3% by mass, 25 ℃, and pH=6). The granulated lithium adsorbents were prepared in three steps. First, porous precursors of NH 4 Al 3 (SO 4 ) 2 (OH) 6 and γ-AlOOH were synthesized hydrothermally using Al 2 (SO 4 ) 3 ·18H 2 O and Urea. The porous powder precursors were then lithiated in aqueous LiOH solution to give mixed porous powders of NH 4 Al 3 (SO 4 ) 2 (OH) 6 and Li-Al-LDHs of Li 2 Al 4 (OH) 12 SO 4 ·xH 2 O. Lithiated powder precursors were finally granulated by ionic crosslinking sodium alginate in CaCl 2 aqueous solutions and deintercalated using water. The precursors and lithiated precursors were characterized by IR spectroscopy , powder XRD , XPS spectroscopy , SEM, TEM, thermal analyses, particle size analysis , and BET surface area. The adsorption isotherm , adsorption kinetics , the effects of pH, temperature, initial lithium concentration, and the anions and cations interference on lithium adsorption-desorption performance of granulated lithium adsorbents were studied. The adsorption isotherm and adsorption kinetics were best fitted with the Langmuir model and pseudo-second-order rate equation , respectively. Lithium adsorption was an endothermic process. The granulated lithium adsorbents were applied to real East Taigener salt lake brine. The lithium adsorption capacity dropped slightly to 9.16 mg/g; the adsorption equilibrium reached within 180 min; the dissolution rate was 0.54% after 10 cycles of adsorption and desorption. The granulated lithium adsorbents prepared show the potential in industrial application.

Developing green and efficient extractants for selectively recovering lithium from salt lake brine is beneficial for alleviating the increasingly growing demand for lithium resources. This study developed a novel hydrophobic deep eutectic solvent (HDES) for selective recovery of Li + from simulated salt lake brine solutions. Under the optimal experimental parameters, the single extraction efficiency of Li + was 70.18 %, β (Li + / Na + ) and β (Li + /Mg 2+ ) were 22.32 and 947.58, respectively. Cycle experiments verified the high stability and good cycle performance of HDES. The conditions affecting the extraction efficiency of Li⁺ were optimized through experiments, and the high stability and good cyclic performance of HDES were verified. The extraction ability and mechanism of HDES for different metal ions were studied based on FTIR spectra combined with density functional theory. The calculation results showed that the order of extraction capacity of HDES for metal ions was: Li + >Na + >Mg 2+ . This calculation results were identical to the experimental results. This research will help develop HDES for the selective recovery of lithium from aqueous solutions containing high concentrations of Mg 2+ , helping to address the urgent global demand for lithium resources.

Positively charged polyamide (PA) nanofiltration (NF) membranes fabricated via interfacial polymerization of polyethyleneimine (PEI) and trimesoyl chloride (TMC) hold great potential for lithium extraction from salt-lake brines, but still face challenges in precise Li + /Mg 2+ separation under high-salinity conditions due to broad pore size distribution and electrostatic shielding. Herein, we designed a PEI/TMC-based PA membrane with enhanced positive charge and narrowed pore size distribution. These properties were regulated by an interlayer fabricated via a Schiff base reaction between polyallylamine (PAA) and glutaraldehyde (GA) on a polysulfone (PSf) substrate. The enrichment and diffusion of amine monomers were regulated by the interlayer, as confirmed through experiments and molecular dynamics simulations. As a result, a PA layer with narrowed pore size distribution ( σ p reduced from 1.36 to 1.21), increased positive surface charge, and reduced thickness was obtained. The optimized interlayer polyamide (iPA) membrane demonstrated a remarkable Li + /Mg 2+ separation factor up to 174.1 in simulated brine, a two-fold increase in water permeance of 5.5 L m −2 h −1 bar −1 , as well as excellent long-term separation stability under high-salinity conditions. This work highlights the potential of iPA membranes for achieving both high lithium purity and recovery, offering a promising avenue for lithium extraction from high-concentration salt-lake brines.
