“…He et al made use of the deep eutectic solvents (DESs) to leach the metal components from spent NCM LIBs. The resultant leaching solution was subjected to a co-precipitation reaction and high-temperature calcination, getting the regenerated LiNi 0.5 Co 0.2 Mn 0.3 O 2 material ( He et al, 2023 ). These reported works inspired us to directly regenerate the NCM material from the spent LIBs.…”

“…Extracting the Ni, Co, Mn and Li from the spent NCM materials and efficiently transforming them into regenerated NCM materials by the designed stoichiometric ratio is not easy to realize. Another problem is the insufficient performance of the generated NCM materials compared with that of commercial new counterpart ( He et al, 2023 ), thus hindering the wide applications.…”

Rational reusing the waste materials in spent batteries play a key role in the sustainable development for the future lithium-ion batteries. In this work, we propose an effective and facile solid-state-calcination strategy for the recycling and regeneration of the cathode materials in spent LiNi0.5Co0.2Mn0.3O2 (NCM523) ternary lithium-ion batteries. By systemic physicochemical characterizations, the stoichiometry, phase purity and elemental composition of the regenerated material were deeply investigated. The electrochemical tests confirm that the material characteristics and performances got recovered after the regeneration process. The optimal material was proved to exhibit the excellent capacity with a discharge capacity of 147.9 mAh g−1 at 1 C and an outstanding capacity retention of 86% after 500 cycles at 1 C, which were comparable to those of commercial NCM materials.

Deep eutectic solvents (DESs) have garnered attention in Li‐ion battery (LIB) recycling due to their declared eco‐friendly attributes and adjustable metal dissolution selectivity, offering a promising avenue for recycling processes. However, DESs currently lack competitiveness compared to mineral acids, commonly used in industrial‐scale LIB recycling. Current research primarily focuses on optimizing DES formulation and experimental conditions to maximize metal dissolution yields in standalone leaching experiments. While achieving yields comparable to traditional leaching systems is important, extensive DES reuse is vital for overall recycling feasibility. To achieve this, evaluating the metal dissolution mechanism can assist in estimating DES consumption rates and assessing process makeup stream costs. The selection of appropriate metal recovery and DES regeneration strategies is essential to enable subsequent reuse over multiple cycles. Finally, decomposition of DES components should be avoided throughout the designed recycling process, as by‐products can impact leaching efficiency and compromise the safety and environmental friendliness of DES. In this review, these aspects are emphasized with the aim of directing research efforts away from simply pursuing the maximization of metal dissolution efficiency, towards a broader view focusing on the application of DES beyond the laboratory scale.
