“…PEG and PHA were mixed with the mole ratio of 1:1 to obtain DESs at 60 °C until the appearance of the liquid state, which was similar to the methods as previously reported. ,,− Magnetic adsorbents could be then synthesized by mixing DESs, Fe 3 O 4 , and LCO with a mass ratio of 1:5:0.1 at 100 °C for 24 h. A previous report suggested that PEG:PHA could dissolve LCO with high efficiency at a mild temperature; however, the leaching efficiency became lower as a result of the formation of the solid product when the temperature was not lower than 100 °C. The possible mechanism for the formation of magnetic adsorbent from DESs, Fe 3 O 4 , and LCO was the redox reaction between LCO and DESs, while Fe 3 O 4 plays the role of possessing magnetism.…”

Dissolution of the cathode by deep eutectic solvents (DESs) is the key and green step to recycle spent lithium-ion batteries (LIBs); moreover, pollutant removal by adsorbents is the efficient route for environment protection. However, the couple of dissolving the LIB cathode and pollutant removal with high sustainability and low cost has not been reported up to now. Here, we for the first time use cheap and green DESs to dissolve LIBs for the preparation of magnetic adsorbents for wastewater treatment and engine oil removal. Results show that the removal efficiency of wastewater could reach as much as 94.5%. More importantly, the magnetic adsorbents after removing pollutants could be easily regenerated by a magnet. In addition to organic dye removal, the magnetic adsorbent could adsorb 576.75% engine oil. This work would provide a novel sustainable and cheap strategy for achieving spent LIB recycle and pollutant removal subsequently with high efficiency.

“…Changing temperature is an efficient method to alter the physical properties − and application efficiency by DESs. ,− Effect of temperature on metal leaching from LCO by PEG/PHA is also investigated. Five temperature points (i.e., 25, 40, 60, 80, 100 °C) are selected as the representative conditions.…”

Efficient Recovery of Valuable Metals from Lithium-Ion Battery Cathodes Using Phytic Acid-Based Deep Eutectic Solvents at a Mild Temperature

et al. 2023

Recycling of waste lithium-ion batteries (LIBs) requires metal leaching from the LIB cathode; however, the metal-leaching process is too challenging to be efficient, green, and mild simultaneously. Moreover, the leaching efficiency at mild conditions by green solvents is not high and needs to be improved urgently. Here, deep eutectic solvents (DESs) composed of poly(ethylene glycol) 200 (PEG) and phytic acid (PHA) are designed to leach Co from LIB cathodes with an ultrahigh metalleaching efficiency of 0.987 at a low temperature of 80 °C for 24 h, which is much higher (ca. 0.3) than the efficiency of previously reported DESs. Moreover, the constituents (PEG and PHA) in DESs are low-cost, sustainable, and biodegradable; particularly, PHA is naturally available in legumes, cereals, dried fruits, vegetables, and other fruits, which are also edible by human beings. This work provides a super highly efficient, sustainable, and mild route for metal leaching from LIB cathodes.

“…Recently, DES ChCl-based nanofluids were formed by dispersion of nano-TiO 2 , Fe 2 O 3 , CuO, SiC, and carbon. These nanofluids exhibited an increase in thermal conductivity and heat capacity up to 4.23 and 26.23%, respectively [ 221 ]. In conclusion, DES-based nanofluids demonstrated potential prospects in the low-grade thermal energy utilization fields, specific heat capacity, thermal conductivity, and wide working temperature ranges.…”

The first report of deep eutectic solvents (DESs) was released in 2003 and was identified as a new member of ionic liquid (IL), involving innovative chemical and physical characteristics. Using green solvent technology concerning economical, practical, and environmental aspects, DESs open the window for sustainable development of nanomaterial fabrication. The DESs assist in different fabrication processes and design nanostructures with specific morphology and properties by tunable reaction conditions. Using DESs in synthesis reactions can reduce the required high temperature and pressure conditions for decreasing energy consumption and the risk of environmental contamination. This review paper provides the recent applications and advances in the design strategy of DESs for the green synthesis of nanomaterials. The strategy and application of DESs in wet-chemical processes, nanosize reticular material fabrication, electrodeposition/electrochemical synthesis of nanostructures, electroless deposition, DESs based nano-catalytic and nanofluidic systems are discussed and highlighted in this review.
