This study develops a carboxyl-functionalized separator integrated with the metal-organic framework MOF-801 on a glass fiber substrate (MGS) via an in situ growth strategy. The innovative design features dual mechanisms: fundamentally, the uniform nanochannels of MOF-801 regulate Zn<sup>2+</sup> flux distribution through spatial confinement effects. Beyond this, DFT calculations and Raman analyses demonstrate that the grafted carboxyl groups selectively capture Zn<sup>2+</sup> via dynamic coordination interactions, simultaneously inducing localized high-concentration electrolyte formation within the channels and effectively suppressing interfacial concentration polarization. The MGS enables Zn||Zn cells to achieve exceptional stability exceeding 8000 h at 1 mA cm<sup>-2</sup> and practical Zn||MnO<sub>2</sub> pouch cells to deliver a capacity of 108 mA h g<sup>-1</sup> at 0.1 A g<sup>-1</sup>.

However, lithium whiskers can form in the early stages of electroplating. These whiskers lead to low Coulombic efficiency due to isolated lithium formation during stripping. The mechanism of whisker formation is not fully understood, and different mechanisms are proposed in the literature. Herein, we computationally explore a stress-driven extrusion mechanism through cracks in the solid-electrolyte-interphase (SEI), which explains the experimentally observed root growth of lithium whiskers. We model the extrusion as a flow of a power-law Herschel-Bulkley fluid parametrized by the experimental power-law creep behavior of lithium, which results in the typical one-dimensional whisker shape. Consequently, in competition with SEI self-healing, SEI cracking determines the emergence of whiskers, giving a simple rule of thumb to avoid whisker formation in liquid electrolytes.</p>","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":" ","pages":"11244-11250"},"PeriodicalIF":9.1,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12291588/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144625010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
