As it was employed as an anode materialnfor lithium-ion batteries (LIBs), high reversible capacity, enhancednrate performance, and excellent cycling stability were achieved asncompared with those of the corresponding cellulose-substance-derivednnanotubular A-titania, R-titania, heterogeneous anatase/rutile titanian(A–R-titania) composite, and commercial P25 powder. This benefitednfrom its unique porous cross-linked three-dimensional structure inheritednfrom the initial cellulose substance scaffold, which enhances thensufficient electrode/electrolyte contact, relieves the severe volumenchange upon cycling, and improves the amount of lithium-ion storage;nmoreover, the high loading content of the silver component in thencomposite improves the electrical conductivity of the electrode. Thenstructural integrity of the composite was maintained upon long-termncharge/discharge cycling, indicating its significant stability.","PeriodicalId":522189,"journal":{"name":"Figshare","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2016-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147893162","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}
