Abstract:ABSTRACT：In this comprehensive study, we conducted a rigorous comparison and evaluation of the synergistic effects between acid solution and ozone for p the separation of positive active materials. Our research unveiled that the infusion of a specific concentration of ozone fortuitously prompts the generation of H2O2, a rather potent oxidizer. This reactive species subsequently interacts with the fluorine moieties present within the polyvinylidene fluoride (PVDF) structure, forming hydrogen fluoride (HF) compounds, thus reducing their inherent adherence to PVDF. Consequently, it magnifies the efficacy of active material separation. Comparatively, this novel ozonation methodology is more secu re, eco-friendly, and user-friendly than traditional recycling techniques, offering a substantial reduction in cost expenditure.
