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.

“…Deep eutectic solvents (DESs) have received considerable attention as green solvents in various applications, such as gas absorption, , extraction, − battery technology, , chromatography, and catalysis . Among all types of DESs, those with choline chloride (ChCl) as hydrogen bond acceptor (HBA) and other natural compounds as hydrogen bond donor (HBD) have been extensively studied due to their desirable properties, such as low cost, low volatility, nontoxicity, and high solubility for a wide range of organic and inorganic compounds. , However, ChCl-based DESs tend to have relatively high viscosity compared to organic solvents, which can significantly impact the mass transfer, heat transfer, and reaction kinetics in chemical processes. , As such, it is crucial to determine the viscosity of ChCl-based DESs before considering them for a particular application …”

Choline chloride (ChCl)-based deep eutectic solvents (DESs) are emerging as promising environmentally friendly alternatives to conventional organic solvents across various applications. However, their relatively high viscosity necessitates careful assessment before implementation. This work proposes an approach to modeling the viscosity of ChCl-based DESs and their mixtures with water using the Grunberg−Nissan mixing rule. We assumed that the viscosity of the hypothetical liquid ChCl could be calculated by the Vogel−Fulcher−Tammann (VFT) model. The VFT parameters of ChCl were regressed using the viscosity data of 17 ChCl-based DESs at various compositions and temperatures. The obtained VFT parameters of ChCl allowed modeling of the viscosity of eight newly measured DESs and their mixtures with water. Five methods were investigated to calculate the interaction parameter (G ij ) in the Grunberg−Nissan mixing rule. It was found that the temperature-dependent G ij yields better results for modeling the viscosity of ChCl-based DESs, whereas the composition-dependent G ij is more suitable for modeling the viscosity of mixtures of DESs and water. The proposed viscosity modeling approach can significantly reduce the experimental effort required to obtain reliable viscosity estimations for ChCl-based DESs and their mixtures with water.

Due to the wide application of lithium iron phosphate (LFP)-based lithium-ion batteries (LIBs), the dissolution of LFP is a crucial step in the process of recycling LFP from LFP-based LIBs. However, the traditional methods for the dissolution of LFP typically require the usage of hazardous solvents, elevated temperatures, or limited efficiency. Achieving efficient, green, and selective dissolution of LFP at low temperatures remains a significant challenge. Here, we, for the first time, find that natural deep eutectic solvents (NADESs) containing glucose and lactic acid show a high Li leaching efficiency of 96.5% for LFP dissolution at a mild temperature, with Li more selectively separated from LFP than Fe. Both glucose and lactic acid in DESs are naturally available, cheap, biodegradable, and nontoxic. This research provides valuable guidance for the development of a green, mild, natural, and efficient process for achieving a sustainable recovery of spent LFP-based LIBs.
