Herein, we propose a facile, one\u2010step liquid\u2010phase mediated method to directly repair S\u2010LFP. By constructing a liquid\u2010phase\u2010mediated system comprising Fe\/Li\u2010based salts and sucrose, this method kinetically accelerates ionic diffusion and ensures homogeneous elemental distribution at a low temperature (300\u2009\u00b0C). Concurrently, the synergistic effect of the liquid\u2010phase\u2010mediated state and a reducing atmosphere facilitates the complete structural restoration from Fe\n                    <jats:sup>3+<\/jats:sup>\n                    to electrochemically active Fe\n                    <jats:sup>2+<\/jats:sup>\n                    . Consequently, the regenerated LFP (R\u2010LFP) demonstrates exceptional electrochemical reversibility, delivering a superior initial capacity of 158.5\u2009mAhg\n                    <jats:sup>\u22121<\/jats:sup>\n                    at 0.1\u2009C. Notably, practical full\u2010cell evaluations exhibit robust long\u2010term cycling stability, retaining 80.0% capacity over 1500 cycles at a high rate of 2\u2009C. Techno\u2010economic analysis confirms that this low\u2010cost, liquid\u2010phase\u2010mediated regeneration protocol outperforms conventional hydro\/pyrometallurgical routes, establishing a viable, scalable closed\u2010loop LFP recycling pathway.\n                  <\/jats:p>","DOI":"10.1002\/cssc.71095","type":"journal-article","created":{"date-parts":[[2026,9,26]],"date-time":"2026-09-26T10:25:12Z","timestamp":1790418312000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Direct Regeneration of Spent LiFePO\n                    <sub>4<\/sub>\n                    Cathodes by Liquid\u2010Phase\u2010Mediated Reconstruction"],"prefix":"10.1002","volume":"19","author":[{"given":"Minghao","family":"Wang","sequence":"first","affiliation":[{"name":"Hubei Longzhong Laboratory Wuhan University of Technology (Xiangyang Demonstration Zone)  Xiangyang Hubei China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenfeng","family":"Li","sequence":"additional","affiliation":[{"name":"Hubei Longzhong Laboratory Wuhan University of Technology (Xiangyang Demonstration Zone)  Xiangyang Hubei China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhuo","family":"Chen","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Advanced Technology for Materials Synthesis and Processing, School of Materials Science and Engineering Wuhan University of Technology  Wuhan Hubei China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuan","family":"Feng","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Advanced Technology for Materials Synthesis and Processing, School of Materials Science and Engineering Wuhan University of Technology  Wuhan Hubei China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Longhao","family":"Rao","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Advanced Technology for Materials Synthesis and Processing, School of Materials Science and Engineering Wuhan University of Technology  Wuhan Hubei China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lun","family":"Li","sequence":"additional","affiliation":[{"name":"Hubei Longzhong Laboratory Wuhan University of Technology (Xiangyang Demonstration Zone)  Xiangyang Hubei China"},{"name":"Hubei Engineering Research Center of RF\u2010Microwave Technology and Application, School of Physics and Mechanics Wuhan University of Technology  Wuhan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shidong","family":"Li","sequence":"additional","affiliation":[{"name":"Hubei Longzhong Laboratory Wuhan University of Technology (Xiangyang Demonstration Zone)  Xiangyang Hubei China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2972-8815","authenticated-orcid":false,"given":"Jiashen","family":"Meng","sequence":"additional","affiliation":[{"name":"Hubei Longzhong Laboratory Wuhan University of Technology (Xiangyang Demonstration Zone)  Xiangyang Hubei China"},{"name":"State Key Laboratory of Advanced Technology for Materials Synthesis and Processing, School of Materials Science and Engineering Wuhan University of Technology  Wuhan Hubei China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,26]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"crossref","first-page":"159920","DOI":"10.1016\/j.apsusc.2024.159920","article-title":"Effective Regeneration of Waste LiFePO4 Cathode Material by Cu Doping Modification","volume":"659","author":"Yao T.","year":"2024","journal-title":"Applied Surface Science"},{"key":"e_1_2_9_3_1","doi-asserted-by":"crossref","first-page":"433","DOI":"10.1016\/j.ensm.2021.02.032","article-title":"Recycling and Environmental Issues of Lithium\u2010Ion Batteries: Advances, Challenges and Opportunities","volume":"37","author":"Barbosa J.
