Sorption and Utilization of Per- and Polyfluoroalkyl Substances in Rechargeable Zinc-Ion Batteries.

ABSTRACT: Per- and polyfluoroalkyl substances (PFAS) are synthetic fluorinated organic compounds linked to severe health issues, highlighting the urgent need for environmentally sustainable remediation strategies. Here, an integrated PFAS sorption and utilization strategy for remediation is reported through incorporating into rechargeable aqueous zinc battery systems at room temperature. As a representative PFAS compound, perfluorooctanoic acid (PFOA) is successfully sorbed on zinc surface via hydrophobic and electrostatic interactions, with over 98% removal efficiency, and partially defluorinated into zinc fluoride after 24 h, enabling their application as an anode protective layer for improved battery performance. This layer enhances electrochemical performance by suppressing dendrite growth and s
