A Flow-Chart for Processing of a Lithium-Manganese Battery using HDES Aliquat 336/Menthol

Designing Low Toxic Deep Eutectic Solvents for the Green Recycle of Lithium‐Ion Batteries Cathodes

“…As the extraction system, Aliquat 336 : mennthol (1 : 1) could not only effectively deal with metal waste in batteries, but also recycle other recyclable components. [23] Zhang and colleagues developed a series of b-diketone-based DESs composed of benzoyl trifluoroacetone as hydrogen, it was found that TRPO : HBTA (1 : 1) had the best lithium separation effect (Figure 11). [126] Besides, after being leached by the above two hydrophobic DESs and washed by the water phase, the loaded metal could be almost completely stripped, while the extraction capacity of DESs remained stable.…”

“…Kozhevnikova and colleagues proposed a hydrometallurgical method for extracting and separating Li, Mn, Al and Fe from the cathode material of the lithium‐manganese batteries. As the extraction system, Aliquat 336 : menthol (1 : 1) could not only effectively deal with metal waste in batteries, but also recycle other recyclable components [23] . Zhang and colleagues developed a series of b‐diketone‐based DESs composed of benzoyl trifluoroacetone as hydrogen, it was found that TRPO : HBTA (1 : 1) had the best lithium separation effect (Figure 11).…”

“…Ionic liquids (ILs) and deep eutectic solvents (DESs) have been used to replace traditional solvents, [23,24] which are considered as new strategies for dissolving and recovering metals that are more environmentally and energy saving. [25] ILs are solutions composed of anions and cations [26] with good thermal stability and high solvation ability, [27,28] which can avoid pollution and biological inhalation toxicity caused by direct escape into the atmosphere, [29] showing high efficiency in metal leaching.…”

New Hydrophobic Deep Eutectic Solvent Based on Di-(2-Ethylhexyl)Phosphoric Acid and Trioctylphosphine Oxide: Properties and Application

“…HDES have a lower melting point compared to the starting components which are a mixture of organic compounds (hydrogen bond acceptor (HBA) and hydrogen bond donor (HBD)). The main advantages of these solvents are ease of preparation, often low cost, availability, and a wide choice of reagents, which makes it possible to vary the physicochemical properties and achieve selectivity to target compounds [3][4][5]. The combination of these and other advantages of HDES makes them one of the most promising extractants, favorably distinguishing them from ionic liquids and classical extractants.…”

Extraction technologies for the recycling of spent power sources

“…В докладе будут представлены современные данные по актуальным подходам к синтезу и применению перспективных экстракционных систем, отвечающих ключевым требованиям технологий замкнутого цикла [1][2][3][4][5][6][7][8][9][10][11][12]. Особое внимание будет уделено новому типу экстрагентов (растворителей)глубоким эвтектическим растворителям.…”
