Here, we report an electrochemical water-mediated strategy for efficient, VFC-free PVDF defluorination under ambient conditions. The method achieves a high fluorine-to-fluoride conversion (93%) and is validated with an industrially relevant capacity of 8.5 kg\u00b7m\n                    <jats:sup>\u22123<\/jats:sup>\n                    \u00b7day\n                    <jats:sup>\u22121<\/jats:sup>\n                    on real wasted battery electrodes containing PVDF as the binder. The high efficiency originates from the spatial confinement of electrochemically generated hydroxide ions near the cathode surface. Mechanistically, isotopic labeling and kinetic Monte Carlo simulations reveal water\u2019s unprecedented dual role as both a reactant and a catalyst, driving an ionic pathway that fundamentally suppresses VFCs. This offers a scalable, sustainable, and nontoxic alternative for the critical challenge of C\u2500F breaking and PFAS defluorination.\n                  <\/jats:p>","DOI":"10.1126\/sciadv.aeg8495","type":"journal-article","created":{"date-parts":[[2026,8,28]],"date-time":"2026-08-28T17:58:31Z","timestamp":1787939911000},"update-policy":"https:\/\/doi.org\/10.34133\/aaas_crossmark","source":"Crossref","is-referenced-by-count":0,"title":["Electrocatalytic polyvinylidene fluoride defluorination with water mediation at room temperature"],"prefix":"10.1126","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6419-1526","authenticated-orcid":true,"given":"Yifan","family":"Bu","sequence":"first","affiliation":[{"name":"College of Chemistry and Molecular Engineering, Peking University, Beijing 100871, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-8285-1624","authenticated-orcid":true,"given":"Peixuan","family":"Li","sequence":"additional","affiliation":[{"name":"Beijing National Laboratory for Condensed Matter Physics, Institute of Physics, Chinese Academy of Sciences, Beijing 100190, China."},{"name":"School of Physics, University of Chinese Academy of Sciences, Beijing 100049, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-0082-9018","authenticated-orcid":true,"given":"Xiayu","family":"Yuan","sequence":"additional","affiliation":[{"name":"The Key Laboratory of Water and Sediment Sciences, Ministry of Education;
