TL;DR: Li et al. as mentioned in this paper explored a new separation method from an electrochemical perspective using LiFePO 4/FePO4 as electrode materials, and the results showed that the extracted capacity of Mg2+ from a solution containing magnesium is only 5.5% of its inserted capacity.

TL;DR: In this paper, Li + exchange capacity and stability of anode-cathode distance, electrolyte temperature, surface density of active substrate and electrolysis time were optimized for brine extraction by membrane electrolysis.

TL;DR: Li et al. as mentioned in this paper proposed a liquid-membrane electrodialysis capable of selectively recovering lithium from high Mg/Li ratio brines, which is composed of an ionic liquid system as the Li+ carrier that presents high selectivity toward Li+ and long-term sustainability, and 2 solid cation-exchange membranes to sandwich the carrier.

TL;DR: Based on the principle of rocking chair Lithium-Ion Batteries, cathode material LiMn2O4 is applied to extract lithium from brine, and a novel lithium-ion battery system of “LiMn 2O4 (anode)|supporting electrolyte|anionic membrane|brine|Li1−xMn IIO4(cathode, 0) as discussed by the authors

TL;DR: A simple, green and effective method, which combined lithium iron phosphate battery charging mechanism and slurry electrolysis process, is proposed for recycling spent lithiumIron phosphate and it is found that the spent LiFePO4 is delithiated and oxidized to FePO4 by the function of e-, which is similar as the LiFe PO4 battery charging process.
