Hydrometallurgical recovery of metals from spent lithium-ion batteries with ionic liquids and deep eutectic solvents

Journal of environmental chemical engineering, Journal Year: 2024, Volume and Issue: 12(4), P. 113248 - 113248

Published: June 5, 2024

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.

Enthalpy-Driven Interaction between Bovine Serum Albumin and Biomass-Derived Low-Melting Mixture Solvents (LoMMSs) for Efficient and Green Purification of Protein

Biomacromolecules, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 9, 2025

Green separation of protein (e.g., bovine serum albumin (BSA)) by low-melting mixture solvents (LoMMSs) depends on the underlying mechanism between BSA and LoMMSs. Here, we for first time find that eco-friendly biomass-derived LoMMSs could be potentially used efficient green purification enthalpy-driven interactions. Biomass-derived possess merits high biocompatibility, degradability, abundance, low cost. A single high-affinity binding site via hydrogen bonding van der Waals forces is observed fluorescence thermodynamic analysis. Experimental results from circular dichroism infrared spectra demonstrate addition stabilizes secondary structure protein. This work provides a valuable indication design cost-effective

Green Recovery of Toxic Prussian White Cathode From Spent All‐Climate Sodium‐Ion Batteries Using Low‐Melting Mixture Solvents (LoMMSs)

Battery energy, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 21, 2025

ABSTRACT A large number of spent sodium‐ion batteries (SIBs) will be produced as SIBs become more widely used. However, components SIBs, such the cathode Prussian white Na 2 Mn[Fe(CN) 6 ], are toxic and hazardous, leading to water soil pollution posing a threat human health. Therefore, recycling is important meaningful. Here, we use phytic acid‐based low‐melting mixture solvents (LoMMSs) for efficient recovery hazardous at mild temperatures. Results show that highest leaching efficiency from could reach 94.7% by polyethylene glycol 200:phytic acid (14:1) 80°C 24 h with liquid/solid ratio 50:1. Furthermore, metal extracted leachate found precipitate when used anti‐solvent, ammonium hydroxide achieving precipitation 89.3% room temperature.
