Existing methods struggle to resolve the signal ambiguity between overlapping fault modes without hardware upgrades. Here, we demonstrate that these distinct fault fingerprints are not lost, but topologically folded within voltage snapshots. We introduce DeFault, a cross-modal diagnostic framework that mathematically unfolds one-dimensional voltage sequences into multi-dimensional phase-space topologies. DeFault employs a bidirectional cross-attention mechanism that acts as an autonomous, physics-aligned filter, explicitly decoding compounded fault modes that remain fundamentally invisible to sequence-based methods. Validated on a field dataset of 16.4 million data records from 99 in-service EVs, our method achieves an average accuracy of 0.96 and an F1 score of 0.84 for four fault types using only 500-second snapshots (spanning <100 mV). This work proves that high-fidelity, interpretable electrochemical diagnosis is achievable on legacy fleets without new sensors, providing a scalable solution for the battery safety crisis.","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"9 1","pages":"105638"},"PeriodicalIF":20.4,"publicationDate":"2026-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149367692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we demonstrate that coupling bulk solvation reconstruction with ChCl-derived interfacial regulation provides an effective strategy for stabilizing zinc electrochemistry under high-temperature operating conditions.

Here, distributed pyrometer measurements and fluorine-resolved electron probe microanalysis provide temperature histories and high-resolution binder distributions. Thermal measurements reveal a temperature plateau during drying despite a continuously decreasing evaporation rate, indicating that solvent evaporation alone cannot fully explain the thermal response.

The as-constructed localized reservoir establishes on-demand bidirectional Zn<sup>2+</sup> fluxes, delivering instantaneous charge compensation to promote the four-electron iodine reduction at the cathode while ensuring fast Zn<sup>2+</sup>desolvation kinetics to facilitate uniform Zn deposition at the anode. Benefitting from this optimized interfacial Zn<sup>2+</sup> compensation, the assembled ZIBs substantially enable an enhanced four-electron iodine conversion with markedly suppressed voltage polarization and Zn dendrites formation, which deliver a high reversible capacity of 262 mAh g<sup>−1</sup> at a high rate of 16 A g<sup>−1</sup> with a capacity retention of 75% over 40,000 cycles at 10 A g<sup>−1</sup>. This work underscores the vital role of fast interfacial Zn<sup>2+</sup> compensation kinetics for achieving high-rate and durable four-electron ZIBs.</div></div>","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"92 ","pages":"Article 105631"},"PeriodicalIF":19.3,"publicationDate":"2026-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149364184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
