“…[177] These solvents have been recently introduced to the metal and battery recycling flowsheets as successful media for electrochemical recovery, [178,179] direct leaching of metals (Li [180] , Ni, Co) from LIB cathodes, and even the dissolution of the polymeric binders in cathodes. [181] Ethylene glycol, [179] urea [182][183][184] based DES have the physical properties required to act as leaching agent and electrolyte for the electrochemical recovery of metals from LIBs. The studies by Wang [181] and Landa-Castro [182] discuss the role of urea and ethylene glycol as reducing agents of the leaching reaction.…”

Being successfully introduced into the market only 30 years ago, lithium‐ion batteries have become state‐of‐the‐art power sources for portable electronic devices and the most promising candidate for energy storage in stationary or electric vehicle applications. This widespread use in a multitude of industrial and private applications leads to the need for recycling and reutilization of their constituent components. Improving the “recycling technology” of lithium ion batteries is a continuous effort and recycling is far from maturity today. The complexity of lithium ion batteries with varying active and inactive material chemistries interferes with the desire to establish one robust recycling procedure for all kinds of lithium ion batteries. Therefore, the current state of the art needs to be analyzed, improved, and adapted for the coming cell chemistries and components. This paper provides an overview of regulations and new battery directive demands. It covers current practices in material collection, sorting, transportation, handling, and recycling. Future generations of batteries will further increase the diversity of cell chemistry and components. Therefore, this paper presents predictions related to the challenges of future battery recycling with regard to battery materials and chemical composition, and discusses future approaches to battery recycling.

“…175 The selection of the HBDs of the DESs was also critical to determine selectivity for extracting certain metals. For example, Landa-Castro et al (2020) 176 compared the performance of reline, glyceline and ethaline for electrodeposition of Ni–Co alloy, and reline rendered the best results to attaining up to 83.6% of nickel leaching and 53.3% of cobalt after 24 h.…”

“…For aluminum batteries, a much cheaper alternative to EMIM-based RTILs are deep eutectic solvents (DES), based on aluminum chloride salts mixed with simple organic molecules (e.g., urea -represented as "ur" thereafter in this work -or acetamide) [12]. Apart from involving low cost precursors in their preparation, DES are highly biodegradable compared to EMIM-based RTILs [13,14]. As a drawback, viscosities in DES are typically at least one order of magnitude larger than those in EMIM-based RTILs [12].…”

Deep eutectic solvents (DES) have emerged as an alternative for conventional ionic liquids in aluminum batteries. Elucidating DES composition is fundamental to understand aluminum electrodeposition in the battery anode. Despite numerous experiemental efforts, the speciation of these DES remains elusive. This work shows how \textit{Ab initio} molecular dynamics (AIMD) simulations can shed light on the molecular composition of DES.
