“…The overall optimal operational conditions were found to be 50 × 10 −3 m HCl and NaOH and an applied electrical field of 30 V that resulted in 50% of boron and 62% of lithium recovery with a specific power consumption of 7.9 kWh m −3 . [308] A more recent work by Jarma et al [309] reported higher recovery values of both boron (ca. 57%) and lithium (ca.…”

“…Accordingly, the feed solution must be predominantly alkaline, while divalent cations such as magnesium and calcium need to be removed previously to this process, as they easily form borate complexes. [306][307][308][309] The experimental setup proposed by Bunani et al presented both conventional ion-exchange membranes and BP membranes (Figure 15b). [306] For this specific kind of operation, the feed solution was neither a natural nor a synthetic brine but Li 2 B 4 O 7 *5H 2 O (ca.…”

The ever-increasing amount of batteries used in today's society has led to an increase in the demand of lithium in the last few decades. While mining resources of this element have been steadily exploited and are rapidly depleting, water resources constitute an interesting reservoir just out of reach of current technologies. Several techniques are being explored and novel materials engineered. While evaporation is very time-consuming and has large footprints, ion sieves and supramolecular systems can be suitably tailored and even integrated into membrane and electrochemical techniques. This review gives a comprehensive overview of the available solutions to recover lithium from water resources both by passive and electrically enhanced techniques. Accordingly, this work aims to provide in a single document a rational comparison of outstanding strategies to remove lithium from aqueous sources. To this end, practical figures of merit of both main groups of techniques are provided. An absence of a common experimental protocol and the resulting variability of data and experimental methods are identified. The need for a shared methodology and a common agreement to report performance metrics are underlined.

“…Electrochemical processes such as ED and EDBM can contribute to soft-water production and the evaluation of waste fluxes [14]. EDBM is a new technology that combines the separation function of electrodialysis with water separation at the bipolar membrane interface, which can convert salts into corresponding acids and bases without adding external components [15]. In this system, anions and cations are separated from wastewater separately and combined with H + and OH − ions via bipolar membranes to form acidic and alkaline solutions [16].…”

In this study, it is aimed to investigate the potential of electrodialysis bipolar membrane (EDBM) systems for the recovery of the concentrate originating from an organized industrial estate (OIE) wastewater treatment system with reverse osmosis (RO). Acids and bases were obtained from a pilot-scale treatment plant as a result of the research. Furthermore, the sustainability and affordability of acids and bases obtained by EDBM systems were investigated. Six cycles were carried out in continuous-flow mode with the EDBM system as batch cycles in the disposal of the concentrate and the production of acids and bases with the EDBM system. For each cycle, the EDBM system was operated for 66, 48, 66, and 80 min, respectively, and the last two cycles were operated for a total of 165 min (70 + 90) with 5 min of waiting. In the EDBM system, a working method was determined such that the cycle flow rate was 180 L/hour, energy to be given to the system was 25 V, and the working pressure was in the range of 0.8–2.5 bar. In the six cycles with the EDBM system, the concentrate, acid and base, conductivity, pH, and pressure increase values were investigated depending on time. Throughout all these studies, the cycles were continued over the products formed in the acid and base chamber. As a result of all the cycles, acid (HCl) production at a level of 1.44% and base (NaOH) production at a level of 2% were obtained.

Lithium hydroxide (LiOH) is rapidly becoming the main precursor for layered oxide cathodes used in lithium ion batteries. Current hydrometallurgical method for LiOH production uses substantial amounts of chemicals and creates wastes, leaving behind a negative environmental footprint. Electrodialysis is emerging as a more sustainable technology for LiOH production, effectively eliminating the conventional chemical addition step and its subsequent waste management. Additionally, hydrogen is generated as a by‐product during the electrodialysis process. Various configurations of the electrodialysis cell have been employed to maximize the energy efficiency of the process and the purity of the LiOH product. Nonetheless, this review found that there is a lack of concerted effort in developing ion exchange membranes specific for LiOH production. Current membrane technologies are not tailored to LiOH production, with limited selectivity to lithium in relative to other monovalent cations, as well as relying heavily on harmful perfluoroalkyl (PFA)‐based polymeric membranes. In this review, special attention is given to the state of the art in the testing and development of membranes, i.e., cation and anion exchange membranes, bipolar membranes, as well as novel membranes that are potentially low‐cost, non‐fluorinated, lithium‐selective with high chemical stability and mechanical robustness.
