Abstract

Designing an environment-friendly delamination process for an end-of-life (EoL) composite cathode is a crucial step in direct cathode recycling. In this study, the green solvent dimethyl isosorbide (DMI) is explored to extract cathode active materials (AMs) from the Al current collector dissolving the polyvinylidene fluoride (PVDF) binder. Mechanistic insight suggests that binder removal from the Al substrate proceeds reducing polymer interchain interaction through DMI penetrating into the PVDF crystalline region. Polymer-solvent interaction may increase establishing hydrogen bond between PVDF and DMI, which facilitates binder removal. Analytical characterizations including H NMR, FTIR, XRD and SEM-EDS reveal that the molecular, micro, and crystal structures of the recovered cathode AMs, PVDF and Al foil are preserved. This finding is expected to provide a replacement for the toxic organic solvent -methylpyrrolidone (NMP) and offers an effective, ecofriendly, and sustainable direct cathode recycling approach for spent Li-ion batteries.

摘要

为报废复合阴极设计一种环境友好的分层工艺是直接阴极回收的关键一步。在本研究中，探索了绿色溶剂二甲基异山梨醇（DMI）从铝集流体中提取阴极活性材料（AM），同时溶解聚偏氟乙烯（PVDF）粘结剂。机理分析表明，通过DMI渗透到PVDF结晶区域减少聚合物链间相互作用，从而实现从铝基板上去除粘结剂。聚合物与溶剂的相互作用可能会增强，在PVDF和DMI之间形成氢键，这有助于去除粘结剂。包括1H NMR、FTIR、XRD和SEM-EDS在内的分析表征表明，回收的阴极活性材料、PVDF和铝箔的分子、微观和晶体结构得以保留。这一发现有望替代有毒有机溶剂N-甲基吡咯烷酮（NMP），并为废旧锂离子电池提供一种有效、环保且可持续的直接阴极回收方法。
