摘要

锂钴氧化物(LCO)的溶解是从废旧LCO基锂离子电池(LIBs)中回收有价值金属(如Co和Li)的关键步骤。然而,LCO的溶解过程要么需要有毒溶剂和高温,要么效率低。深共晶溶剂(DESs)是溶解LCO的潜在绿色溶剂。本文发现,以聚乙二醇(PEG)为氢键受体,抗坏血酸(AA)为氢键供体的DESs在80℃和72小时内可溶解LCO,Co浸出率为84.2%,高于常见DESs的参考文献。此外,DESs的两种成分(即PEG和AA)都是廉价的、可生物降解的和生物相容的。AA可以很容易地从天然水果或蔬菜中大量提取。它为LCO的绿色、温和和有效溶解提供了一个新的指南,旨在可持续回收废LIBs。

Mild and efficient recovery of lithium-ion battery cathode material by deep eutectic solvents with natural and cheap components

Dissolution of lithium cobalt oxide (LCO) is the key step for the recovery of valuable metals (e.g., Co and Li) from spent LCO-based lithium-ion batteries (LIBs). However, the dissolution process of LCO either needs toxic solvents, and high temperature, or shows low efficiency. Deep eutectic solvents (DESs) are potential green solvents to dissolve LCO. Here, DESs with polyethylene glycol (PEG) as hydrogen bond acceptor and ascorbic acid (AA) as hydrogen bond donor are found to dissolve LCO with 84.2% Co leaching efficiency at 80 oC and 72 h, which is higher than that from the reported references by common DESs. Furthermore, both DESs components (i.e., PEG and AA) are cheap, biodegradable, and biocompatible. AA could be easily and abundantly extracted from natural fruits or vegetables. It provides a new guide for the green, mild, and efficient dissolution of LCO aiming at sustainable recovery of spent LIBs.
