Spent Li-ion battery (LIB) recovery has become the hot research area due to its surge in quantity and release of heavy metals and toxic substances harmful to the environment. Green and efficient recovery methods are of great significance for the recovery of valuable metals. Herein, an oxalic acid-based deep eutectic solvent (DES) with the weak acidic character and reducibility of oxalic acid was designed for the recovery of valuable metals from spent LIBs via a sustainable and convenient process. Nearly 96.1% of Li and 96.3% of Co can be extracted from lithium cobalt oxide at 120 °C. The DES can extract valuable metals from cathode materials and separate metal ions by itself after extraction without destroying its own structure in a one-pot extraction process. The composition and the structure of DES have been maximum retained and could be intact recycled for another recovery process. After five cycles, the Li and Co extraction efficiencies were maintained above 92.9 and 74.5%, respectively. This work provides a sustainable one-pot recovery process with inexpensive and simple operations for valuable metal recovery from spent LIBs.

通过一锅提取工艺从废锂离子电池中可持续和方便地回收有价值的金属
废锂离子电池（LIB）回收由于其数量激增和释放对环境有害的重金属和有毒物质而成为研究的热点。绿色高效的回收方法对于有价金属的回收具有重要意义。在此，设计了一种具有草酸弱酸性和还原性的草酸基深共熔溶剂 (DES)，用于通过可持续且方便的工艺从废 LIB 中回收有价值的金属。在 120°C 时，钴酸锂可以提取近 96.1% 的锂和 96.3% 的钴。DES可以从正极材料中提取有价金属，提取后自行分离金属离子，在一锅提取过程中不破坏自身结构。DES 的组成和结构得到了最大程度的保留，可以完整地回收用于另一个回收过程。五个循环后，锂和钴的提取效率分别保持在 92.9% 和 74.5% 以上。这项工作提供了一种可持续的单锅回收过程，操作简单且廉价，可从废 LIB 中回收有价值的金属。
