However, existing methods for evaluating retired batteries are time- and resource-consuming, hindering efficient screening for later recycling or reuse. Herein, combining optical fiber sensors and interpretable machine learning (ML), we establish a data-driven framework for retired battery datasets with 265 cells of different chemistries (LiFePO4/graphite, LiMn2O4/graphite) and achieve ultrafast state of health diagnosis within 3 min, offering mean absolute errors of 1.17% and 2.78%, respectively. The proposed data-driven framework identifies the salient regions in the time-resolved multivariable data and helps to uncover underlying thermodynamic/kinetic aging mechanisms. We also demonstrate the incorporated thermal information obtained via optical fibers complements voltage signals by improving prediction accuracy and antinoise ability. This work not only showcases the potential of battery sensing in retired battery diagnosis but also unlocks the unexplored synergy between sensing and interpretable ML for diverse battery applications.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"10 2","pages":"862–871 862–871"},"PeriodicalIF":19.3,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143402326","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}

To address this challenge, here, we report the design of an aluminum fluoride nanowire membrane as a conversion interlayer to regulate lithium deposition for significantly more stable and safe lithium metal batteries. The interlayer generates a LiF-rich solid electrolyte interphase and alloy nanoparticles in contact with lithium to offer active sites guiding lithium nucleation, regulating lithium deposition, and increasing Coulombic efficiencies. With such an interlayer, lithium metal full cells show significantly improved stability compared to those with bare Cu, when paired with a LiFePO4 or LiNi0.8Co0.1Mn0.1O2 cathode. Our results indicate that using an aluminum fluoride interlayer can be a promising strategy in realizing lithium metal batteries with high specific energy density.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"10 2","pages":"853–861 853–861"},"PeriodicalIF":19.3,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acsenergylett.4c03216","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143402382","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}

The experimental measurements are in quantitative agreement with theoretical predictions based on the concentrated solution theory. The properties of two electrolytes are compared using a new plot wherein the length-normalized limiting current, ilimL, is plotted as a function of the length-normalized potential drop, Φlim/L, in symmetric cells with electrolyte thickness, L. We propose that electrolyte design should aim to obtain the largest values of ilimL and the smallest values of Φlim/L. Using this criterion, PPM/LiTFSI is a better polymer electrolyte than PEO/LiTFSI. We hope that PPM/LiTFSI will serve as a benchmark for developing next-generation polymer electrolytes.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"10 2","pages":"831–836 831–836"},"PeriodicalIF":19.3,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143402194","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}
