As a result, Li||graphite half cells using LiDFP electrolyte exhibit outstanding rate performance (90.8% capacity retention at 30 C) and excellent cycle stability (82.2% capacity retention after 5000 cycles) at room temperature. Moreover, graphite||graphite full cells with LiDFP electrolyte demonstrate stable discharge capacity across a temperature range of −20 to 40 °C, expanding the potential applications of LiDFP. This work establishes a novel strategy for optimizing the interphase through electrolyte design, paving the way for all-climate DIBs with improved performance and stability.</div></div>","PeriodicalId":15728,"journal":{"name":"Journal of Energy Chemistry","volume":"109 ","pages":"Pages 100-108"},"PeriodicalIF":13.1,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144241623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
