The primarynidentified failure mechanism of the SPE cell is capacity fade, regardlessnof the Li manufacturer. While the cathode’s role in capacitynfade is evident, the Li anode significantly influences cycling performance,nwith Li foil cells cycling 50% longer than Li chip cells, a statisticalndifference. Post-mortem scanning electron microscopy and X-ray photoelectronnspectroscopy results attribute the Li chip’s faster capacitynfade to a loss of contact and continuous growth of the solid electrolyteninterphase (SEI). Conversely, Li foil maintains consistent contactnwith the solid polymer, displaying a thin and stable SEI. Additionally,nfailure mechanisms between a gel electrolyte in previous work andnthe dry SPE are compared.","PeriodicalId":522095,"journal":{"name":"Figshare","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147891390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
