The high demand for lithium (Li) relates to clean, renewable storage devices and the advent of electric vehicles (EVs). The extraction of Li ions from aqueous media calls for efficient adsorbent materials with various characteristics, such as good adsorption capacity, good selectivity, easy isolation of the Li-loaded adsorbents, and good recovery of the adsorbed Li ions. The widespread use of metal-based adsorbent materials for Li ions extraction relates to various factors: (i) the ease of preparation via inexpensive and facile templation techniques, (ii) excellent selectivity for Li ions in a matrix, (iii) high recovery of the adsorbed ions, and (iv) good cycling performance of the adsorbents. However, the use of nano-sized metal-based Lithium-ion sieves (LISs) is limited due to challenges associated with isolating the loaded adsorbent material from the aqueous media. The adsorbent granulation process employing various binding agents (e.g., biopolymers, synthetic polymers, and inorganic materials) affords composite functional particles with modified morphological and surface properties that support easy isolation from the aqueous phase upon adsorption of Li ions. Biomaterials (e.g., chitosan, cellulose, alginate, and agar) are of particular interest because their structural diversity renders them amenable to coordination interactions with metal-based LISs to form three-dimensional bio-composite materials. The current review highlights recent progress in the use of biopolymer binding agents for the granulation of metal-based LISs, along with various crosslinking strategies employed to improve the mechanical stability of the granules. The study reviews the effects of granulation and crosslinking on adsorption capacity, selectivity, isolation, recovery, cycling performance, and the stability of the LISs. Adsorbent granulation using biopolymer binders has been reported to modify the uptake properties of the resulting composite materials to varying degrees in accordance with the surface and textural properties of the binding agent. The review further highlights the importance of granulation and crosslinking for improving the extraction process of Li ions from aqueous media. This review contributes to manifold areas related to industrial application of LISs, as follows: (1) to highlight recent progress in the granulation and crosslinking of metal-based adsorbents for Li ions recovery, (2) to highlight the advantages, challenges, and knowledge gaps of using biopolymer-based binders for granulation of LISs, and finally, (3) to catalyze further research interest into the use of biopolymer binders and various crosslinking strategies to engineer functional composite materials for application in Li extraction industry. Properly engineered extractants for Li ions are expected to offer various cost benefits in terms of capital expenditure, percent Li recovery, and reduced environmental footprint.

“…Currently, the methods for the lithium extraction from liquid resources are mainly based on the solvent extraction, precipitation, membrane separation, electrochemistry, and adsorption methods. , The adsorption method is considered a low-cost, nonpolluting, effective, and selective method for the lithium extraction from brines. So far, the adsorbents used for the lithium extraction are mainly classified as aluminum-based adsorbents, , lithium–titanium oxides , (LTO, Li 2 TiO 3 and Li 4 Ti 5 O 12 ), and lithium–manganese oxides − (LMO, LiMn 2 O 4 , Li 4 Mn 5 O 12 , and Li 1.6 Mn 1.6 O 4 ). Aluminum-based adsorbents have a high selectivity for Li + ions, while their lithium adsorption capacity is relatively poor.…”

In this work, novel lithium manganese oxide ion sieves (LISs) H 1.6 Mn 1.54 Al 0.02 Cr 0.04 F y O 4−y codoped with Al, Cr, and F ions were synthesized to improve their lithium adsorption performance. The resulting anion-and cation-codoped LISs maintain the spinel structure. Particularly, the introduction of F ions forms a fluoride coating layer on the surface of LISs, playing an important role in stabilizing the LIS structure. Moreover, some Mn 3+ ions are partially replaced by Al 3+ and Cr 3+ ions and some of the surface O 2− ions are replaced by F − ions, forming the stronger Al−O, Cr−O, and metal−fluorine bonds. The synergistic effect of the anion and cation codoping enhances the structural stability of LIS. Compared with undoped and double-doped LISs, the triple-doped LIS H 1.6 Mn 1.54 Al 0.02 Cr 0.04 F 0.1 O 3.9 (HMACFO-10) exhibits a lower manganese dissolution loss, enhanced Li + adsorption performance, and better reusability. In addition, HMACFO-10 affords good adsorption selectivity for Li + ions from brines.
