ACS Applied Materials & Interfaces, Journal Year: 2024, Volume and Issue: 16(8), P. 10267 - 10276

Effective separation of cathode materials from the current collector is a critical step in recycling spent lithium-ion battery (LIB). This typically necessitates decomposition or dissolution organic binder, poly(vinylidene fluoride) (PVDF), to achieve efficient recovery materials. However, this process requires high temperature, between 400 and 600 °C, can lead side reactions, such as oxidation/brittleness, materials, formation metal fluorides. In study, we propose that non-thermal plasma (NTP) treatment be used an extremely aluminum at near room temperature. Instead relying on PVDF decomposition, which temperatures, deactivated by partially breaking down long molecular chains with appropriate NTP conditions. With total time around 2000 s environmental temperature approximately 80 minor reactions avoided. The rate reach up 95.69%, high-quality obtained only 0.02 wt % impurity content. research could potentially offer new approach toward minimizing steps reducing energy consumption LIBs. It also extended broader range electronic wastes.

ABSTRACT The growing use of lithium iron phosphate (LFP) batteries has raised concerns about their environmental impact and recycling challenges, particularly the recovery Li. Here, we propose a new strategy for priority Li precise separation Fe P from spent LFP cathode materials via H 2 O‐based deep eutectic solvents (DESs). Through adjusting form metal complexes precipitation mode, above 99.95% can be dissolved in choline chloride‐anhydrous oxalic acid‐water (ChCl‐OA‐H O) DES, high efficiency 93.41% 97.40% accordingly are obtained. effects main parameters comprehensively investigated during leaching processes. mechanism pretreated is clarified rate‐controlling step heterogeneous dissolution reactions also identified. Results show that soluble phases 3 (PO 4 ) O formed after roasting pretreatment, Li(I) ions tend to C precipitates with 2− process so recovered preferentially purity 99.82%. After UV‐visible light irradiation, Fe(III) converted into Fe(II) ions, which react FeC by content, as Na PO ∙12H (99.98% purity). Additionally, plan used DES proposed performances still maintain stable three circles. method offers an approach simple process, efficiency, waste‐free DESs.
