Here we argue that interfacial failure of layered cathodes is not a collection of isolated events but a coupled failure cascade in which chemical, structural, and mechanical factors amplify one another along a causal chain\u2014surface residual alkali and oxygen release, heterogeneous phase transitions and surface reconstruction, stress concentration and crack propagation, and finally electrolyte infiltration with self-catalyzed formation of fresh interfaces. Starting from this cascade, we extract the corresponding modulation targets and, organized along the atomic\u2013nano\u2013micro length scale, survey single-axis strategies that include pillar-ion pinning, in situ conversion of residual alkali, gradient and epitaxial coatings, intergrown heterointerfaces, multifunctional coatings, and concentration-gradient particles. We then synthesize cross-scale synergistic paradigms\u2014coating-plus-doping cascades, mechano-electrochemical coupling, dynamically stable interfaces under wide-temperature and high-voltage operation, and cathode\u2013electrolyte interphase (CEI) engineering\u2014and show that interface modulation is shifting from passive isolation toward active regulation. We close by distilling actionable design principles and outlining prospects for responsive interfaces and rational design.<\/jats:p>","DOI":"10.3390\/molecules31193551","type":"journal-article","created":{"date-parts":[[2026,10,5]],"date-time":"2026-10-05T10:02:27Z","timestamp":1791194547000},"page":"3551","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Interfacial Failure Cascade and Modulation Strategies for Layered Oxide Cathodes in Sodium-Ion Batteries"],"prefix":"10.3390","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2123-7408","authenticated-orcid":false,"given":"Yong-Gang","family":"Sun","sequence":"first","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Yancheng Institute of Technology, Yancheng 224051, China"},{"name":"Jiangsu Key Laboratory of Coastal Photovoltaic Technology and System, Yancheng Institute of Technology, Yancheng 224051, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hao-Jie","family":"Fan","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Yancheng Institute of Technology, Yancheng 224051, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi-Han","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Yancheng Institute of Technology, Yancheng 224051, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian","family":"Xiong","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Yancheng Institute of Technology, Yancheng 224051, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jin-Yi","family":"Ding","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Yancheng Institute of Technology, Yancheng 224051, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun-Yu","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Yancheng Institute of Technology, Yancheng 224051, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jia-Feng","family":"Ru","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Yancheng Institute of Technology, Yancheng 224051, China"},{"name":"School of Chemistry and Pharmaceutical Sciences, Guangxi Normal University, Guilin 541004, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meng-Shuang","family":"Lei","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Yancheng Institute of Technology, Yancheng 224051, China"},{"name":"School of Chemistry and Pharmaceutical Sciences, Guangxi Normal University, Guilin 541004, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chen","family":"Cheng","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Yancheng Institute of Technology, Yancheng 224051, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8431-9021","authenticated-orcid":false,"given":"Xi-Jie","family":"Lin","sequence":"additional","affiliation":[{"name":"School of Chemistry and Pharmaceutical Sciences, Guangxi Normal University, Guilin 541004, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,10,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"4230","DOI":"10.1039\/D3CS00929G","article-title":"Routes to high-performance layered oxide cathodes for sodium-ion batteries","volume":"53","author":"Wang","year":"2024","journal-title":"Chem.
