“…In our work, Li + ions were selectively recovered from brine with an energy consumption of 1.76 Wh mol −1 . The energy consumption in our work is more efficient than that in the previous reports on λ‐MnO 2 /Pt, LiFePO 4 /Ag, Li 1−x Ni 0.33 Co 1/3 Mn 1/3 O 2 /Ag, and LiMn 2 O 4 /Zn, and comparable with λ‐MnO 2 /Ag and Li 1−x Ni 0.5 Mn 1.5 O 4 /Ag . It is worth noting that the present LiMn 2 O 4 nanorods/Ni HCF III cell exhibits the highest recovery capacity among the previously reported recovery systems listed in Table .…”

Nowadays the world's demand for lithium extraction has been vigorously growing, especially driven by an increased lithium use in new consumer electronic battery technologies and electric cars. Conventional methods for industrial lithium production from two major sources of underground brine deposits and mineral ore deposits are straightforward, but time‐consuming from several months to a few years to complete. Therefore, efficient and low‐energy‐consuming lithium extraction is highly desirable. Here, we develop an attractive electrochemical method for lithium recovery with low energy consumption and high selectivity based on a cell system using LiMn2O4 nanorods. Despite the presence of other cations, lithium ions can be selectively recovered from brine with a low energy consumption of 1.76 Wh mol−1. The resulting electrochemical cell system using LiMn2O4 nanorods exhibits outstanding cyclability with a recovery capacity retention of 37.4 % over 200 cycles. The lithium extraction strategy is effective and economical, which holds great promise for future lithium recycling.

“…This methodology has a critical limitation: in order to compare different studies using the same Li‐capturing electrode, source and especially recovery solutions have to be similar, which is not often the case in literature. The Li selectivity has also been calculated as the ratio of the distribution coefficients (

K_{D}^{Li}

) of Li‐ion with respect to other cation (

K_{D}^{M}

) from the brine solution to the electrode material [ 62,63 ]

α_{M}^{Li} = \frac{K_{D}^{Li}}{K_{D}^{M}}

“…[ 135 ] Chung et al studied LiNi 1/3 Co 1/3 Mn 1/3 O 2 (LNCM) as a Li recovery electrode and Ag as a counter electrode. [ 62 ] The authors evaluated the effect of the current rate, from 0.56 C to 2.88 C, in 30 × 10 −3 m equimolar of mixed cation solution (Li, Na, Mg, K, and Ca) without cutoff potential limits and stopped the measurements after 20 min of applied current. The C‐rates and percentage of specific capacity provided were calculated based on the practical capacity reported in the literature for aqueous batteries (93 mAh g −1 ), [ 136 ] instead of using the theoretical capacity of LNCM (275 mAh g −1 ).…”

“…Silver has been a wingspread alternative to Pt. In spite of its cost that would preclude its commercial use, Ag has been extensively employed [ 45–47,59,62,63 ] because of its easy preparation and reactivity with Cl − , one of the main components of Brine lakes, to form AgCl. The potential versus time profile of this reaction is a plateau, allowing the utilization of an Ag/AgCl electrode simultaneously as counter and pseudoreference electrode, especially interesting for cell working with volume in the range of hundreds of microliters.…”

Electrochemical Methods for Lithium Recovery: A Comprehensive and Critical Review

Due to the ubiquitous presence of lithium‐ion batteries in portable applications, and their implementation in the transportation and large‐scale energy sectors, the future cost and availability of lithium is currently under debate. Lithium demand is expected to grow in the near future, up to 900 ktons per year in 2025. Lithium utilization would depend on a strong increase in production. However, the currently most extended lithium extraction method, the lime‐soda evaporation process, requires a period of time in the range of 1–2 years and depends on weather conditions. The actual global production of lithium by this technology will soon be far exceeded by market demand. Alternative production methods have recently attracted great attention. Among them, electrochemical lithium recovery, based on electrochemical ion‐pumping technology, offers higher capacity production, it does not require the use of chemicals for the regeneration of the materials, reduces the consumption of water and the production of chemical wastes, and allows the production rate to be controlled, attending to the market demand. Here, this technology is analyzed with a special focus on the methodology, materials employed, and reactor designs. The state‐of‐the‐art is reevaluated from a critical perspective and the viability of the different proposed methodologies analyzed.

Rapid developments in the electric industry have promoted an increasing demand for lithium resources. Lithium in salt lake brines has emerged as the main source for industrial lithium extraction, owing to its low cost and extensive reserves. The effective separation of Mg 2? and Li ? is critical to achieving high recovery efficiency and purity of the final lithium product. This paper summarizes Mg 2? /Li ? separation materials and methods in the field of lithium recovery from salt lake brines. The review begins with an introduction to the global distribution and demand for lithium resources, followed by a description of the materials used in various separation techniques, including precipitation, adsorption, solvent extraction, nanofiltration membrane, electrodialysis, and electrochemical methods. A comparison, analysis, and outlook of such methods are comprehensively discussed in terms of principles, mechanisms, synthesis/operation, development, and industrial applications. We conclude with a presentation of challenges and insights into the future directions of lithium extraction from salt lake brines. A combination of the advantages of various materials is the most logical step toward developing novel methods for extracting lithium from brines with high separation selectivity, stability, low cost, and environmentally friendly characteristics.
