One way to recover battery-grade lithium carbonate from oxalic acid leachate is to use synergistic solvent extraction with β-diketone and neutral extractant in kerosene.
Conclusions A very efficient way to achieve an early selective lithium recovery from spent lithium-ion batteries was demonstrated in this work. Oxalic acid, the strongest of the organic acids, reacts with lithium, nickel, manganese, and cobalt oxide to form their respective oxalates.
A novel synergistic extractant consisting of a deep eutectic solvent (DES) and tri-n-butyl phosphate (TBP) is proposed for selective extraction of valuable metals from waste lithium-ion batteries (LIBs).
In traditional hydrometallurgical processes, the black mass from spent lithium-ion batteries (after discharging, dismantling, crushing, and sorting) is dissolved in inorganic acids such as sulfuric acid, hydrochloric acid, and nitric acid, usually with the addition of a reducing agent such as hydrogen peroxide.
Such an extraction system has been reported to efficiently extract Li over other alkali metal ions from brines [, , ], sulfuric acid streams [15, 25], and mother liquor of the crystallization process [29, 30].
Solvent extraction for the recycling valuable metals from the leaching liquor of cathode material was summarized. Organic solvent extraction and supercritical extraction for the electrolyte recovery were summarized. The industrial examples of recovering valuable metals by solvent extraction were listed.
