Selective and highly efficient extraction technologies for the recovery of critical metals including lithium, nickel, cobalt, manganese from spent lithium-ion battery (LIB) cathode materials are essential in driving circularity. The tailored deep eutectic solvent (DES) choline chloride–formic acid (ChCl–FA) demonstrated a high selectivity efficiency extracting mixed (LiFePO4:Li(NiCoMn)1/3O2 mass ratio 1:1) under mild conditions (80 °C, 120 min) with solid–liquid 1:200. leaching performance could be further enhanced by mechanochemical processing because particle size reduction, grain refinement, internal energy storage. Furthermore, reactions effectively inhibited undesirable nontarget elements (iron phosphorus), thus promoting metals. This was achieved through preoxidation Fe stability iron phosphate framework, which significantly increased separation factor to 56.9 1475. proposed combination ChCl–FA reaction can achieve selective multisource LIBs conditions.

Separation and reaction processes are key components employed in the modern chemical industry, former accounts for majority of energy consumption therein. In particular, hydrocarbon separation purification processes, such as aromatics extraction, desulfurization, denitrification, challenging petroleum refinement, an industrial cornerstone that provides raw materials products used human activities. The major technical shortcomings solvent extraction volatile loss, product entrainment leading to secondary pollution, low efficiency, high regeneration due use traditional organic solvents with boiling points agents. Ionic liquids (ILs), a class designable functional or materials, have been widely replace conventional after nearly 30 years rapid development. Herein, we provide systematic comprehensive review state-of-the-art progress ILs field extractive (i.e., denitrification) including (i) molecular thermodynamic models IL systems enable large-scale screening candidates phase equilibrium prediction processes; (ii) structure-property relationships between anionic cationic structures their performance selectivity distribution coefficients); (iii) IL-related mechanisms (e.g., magnitude, strength, sites intermolecular interactions depending on system structure); (iv) process simulation design at scale based validated models. short, this Review easy-to-read exhaustive reference mixtures from multiscale perspective molecules, thermodynamics, processes. It also extends analogs, deep eutectic (DESs) research area, discusses current challenges faced by related fields well future directions opportunities.
