Deep eutectic solvent‐assisted selective extraction of valuable metals from waste lithium‐ion batteries

AIChE Journal, Journal Year: 2024, Volume and Issue: 70(5)

Published: March 4, 2024

Abstract A novel synergistic extractant consisting of a deep eutectic solvent (DES) and tri‐n‐butyl phosphate (TBP) is proposed for selective extraction valuable metals from waste lithium‐ion batteries (LIBs). The efficiencies Ni 2+ , Co Mn were 99.8%, 99.1%, 95.9%, respectively, high‐purity Li + was enriched in the raffinate after single‐stage extraction. Valuable metal salts, lithium carbonate (92.3 wt%) cobalt oxalate (94.9 wt%), obtained. DES TBP retained its high performance even multiple regeneration cycles. process followed so‐called “cation exchange mechanism” with thermodynamic properties Δ H < 0, G S 0. molecular‐level mechanism demonstrated that dominated by both electrostatic coordination interactions between ions DES/TBP, based on quantum chemical calculations. This study aims to provide new strategy recycling LIBs.

The widespread adoption of lithium-ion batteries (LIBs) in modern electric vehicles has successfully addressed the issues limited oil and gas resources, as well environmental degradation. This development is crucial for achieving "carbon neutrality" reduce peaking". Proper disposal used LIBs vital effective resource management avoiding pollution potential hazards associated with toxic substances. Moreover, a significant weight fraction constituted by so-called critical raw materials (CRMs), presenting high supply risk price variability. Over past few years, considerable progress been made developing processes safe treatment material recovery from spent LIBs, besides CRMs. Among them, hydrometallurgical recycling components employing affordable eco-friendly ionic liquids (ILs) deep eutectic solvents (DESs) gained attention their potentially superior selectivity, low energy consumption, impact. Such present various advantages over traditional organic employed liquid separations terms volatility, safety, chemical thermal stability, recyclability, selectivity. review provides an overview most recent advances application ILs DESs to recover CRMs LIBs.

Addressing the Reuse of Deep Eutectic Solvents in Li‐Ion Battery Recycling: Insights into Dissolution Mechanism, Metal Recovery, Regeneration and Decomposition

ChemSusChem, Journal Year: 2024, Volume and Issue: 17(20)

Published: May 10, 2024

Abstract Deep eutectic solvents (DESs) have garnered attention in Li‐ion battery (LIB) recycling due to their declared eco‐friendly attributes and adjustable metal dissolution selectivity, offering a promising avenue for processes. However, DESs currently lack competitiveness compared mineral acids, commonly used industrial‐scale LIB recycling. Current research primarily focuses on optimizing DES formulation experimental conditions maximize yields standalone leaching experiments. While achieving comparable traditional systems is important, extensive reuse vital overall feasibility. To achieve this, evaluating the mechanism can assist estimating consumption rates assessing process makeup stream costs. The selection of appropriate recovery regeneration strategies essential enable subsequent over multiple cycles. Finally, decomposition components should be avoided throughout designed process, as by‐products impact efficiency compromise safety environmental friendliness DES. In this review, these aspects are emphasized with aim directing efforts away from simply pursuing maximization efficiency, towards broader view focusing application beyond laboratory scale.
