“…Wang and co‐workers used a reline mixture to extract Li and Co from spent LIBs (Figure 9e). [ 134 ] The strong reducibility of reline enables the extraction at a mild condition (180 °C) with a short reaction time of 12 h. They also found Co can be recycled as Co 3 O 4 using H 2 C 2 O 4 and NaOH precipitants through a dilution–precipitation–calcination process. Other DES systems such as ChCl/citric acid, [ 135 ] p‐toluenesulfonic acid monohydrate/ChCl, [ 136 ] and polyethylene glycol/thiourea [ 137 ] were also studied for the recycling of LiCoO 2 from spent LIBs.…”

The pursuit of sustainable energy utilization arouses increasing interest in efficiently producing durable battery materials and catalysts with minimum environmental impact. As green, safe, and cheap eutectic mixtures, deep eutectic solvents (DESs) provide tremendous opportunities and open up attractive perspectives as charge transfer and reaction media for electrochemical energy storage and conversion (EESC). In this review, the fundamental properties of DESs are first summarized. Then, the important roles that DESs play in various EESC technologies including advanced electrolytes for batteries/supercapacitors, media for the preparation of electrode materials and catalysts, and extracting agents for battery recycling are systematically reviewed. A particular focus is placed on the fundamental understanding of structure-composition-property-performance relationships. Finally, the challenges for the controllable design of DESs for EESC applications and future developments are presented. This review is expected to shed light on developing advanced DESs for next-generation EESC systems.

“…The reducing power of DESs, therefore, plays a key role in dissolving transition metals. Zhang and colleagues proposed a novel, simple, and robust experimental methodology based on DFT calculation and CV analysis to identify the reducibility of DESs 33 . After systematic investigations (Figure 2D and E), the good suitability of ChCl:urea‐based DES was proved due to a more strong reducibility.…”

Lithium‐ion batteries (LIBs) are booming in multiple fields due to a rapid development in the last decade. However, limited by operational lifespans, a growing number of spent LIBs reaching the end of their lives are consequently faced with serious accumulation and descended to hazardous waste. Without proper disposal, the spent LIBs will inevitably cause negative influence on the ecology and undermine the sustainable manufacture of LIBs. The initial research of recycling strategies mainly focused on the optimization of metallurgical processes. Recently, the sustainability of the recycling process has attracted much more attention and become an important factor. Here, we summarize the recent progress of the spent LIBs recycling from a sustainable perspective, especially discussing the green innovations in recycling strategies for spent LIBs. Through this article, we expect to reveal the challenges and developing tendency of the recycling strategies and provide a guideline for future researches on processing spent LIBs and beyond, like the recycling of the solid‐state lithium metal batteries.

Deep eutectic solvents (DESs) appeared recently as a new class of green designer solvents. The recovery of metals using hydrometallurgy is of major importance with the growth in metal demand. Several authors used these solvents for the hydrometallurgical recovery of metals from primary and secondary resources, and these studies are reviewed in the present work. Hydrophilic DESs can be used for the leaching of metals and have great potential to replace mineral acids, and even to reduce water consumption. Efficient and selective leaching of metals from minerals or wastes is feasible by using DESs. However, the kinetics of leaching as well as the physicochemical properties of DESs are still limiting their large-scale application. Electrochemical recovery from DES is also possible but deserves further investigation. Finally, the recovery of metals from aqueous solutions using hydrophobic DESs was studied in several works. For the solvent extraction of metals, hydrophobic DESs constitute credible alternative ionic liquids.
