摘要

低熔点混合溶剂(LoMMSs)和离子液体(ILs)被认为是回收锂离子电池(LIBs)正极的绿色溶剂,具有很高的可持续性。意外的是,我们首次发现基于 LoMMSs 或 ILs 的碳材料和锂离子电池回收浸出液释放到水中会导致严重的溶解有机物(DOM)污染。此外,由于 DOM 浓度较高,京津冀地区河流中的 COD、NH4-N 和总磷浓度也相对较高。这项工作提示我们,在材料制备和惰性离子交换树脂回收中应用所谓的绿色 LoMMSs 和 ILs 时应高度谨慎,以尽量减少 DOM 对京津冀地区河流的污染。

Green low-melting mixture solvents/ionic liquids-based carbon materials and lithium-ion batteries recycling leachate unexpectedly cause water pollution from dissolved organic matter
Low-melting mixture solvents (LoMMSs) and ionic liquids (ILs) are regarded as green solvents for the recovery of lithium-ion batteries (LIBs) cathode with high sustainability. Unexpectedly, we find for the first time that the release of LoMMSs- or ILs-based carbon materials and LIBs recycling leachate into water can lead to significant pollution from dissolved organic matter (DOM). Moreover, COD, NH4–N and total P concentration in river from Jingjinji Region is relatively high due to the high concentration of DOM. This work would provide us a hint that the application of so-called green LoMMSs and ILs in materials preparation and LIBs recovery should be treated with high caution in order to minimize DOM pollution for the rivers in Jingjinji Region.
