High-surface-areanreduced graphene oxide (rGO) has been used as the conductive substratento avoid the aggregation of NiGa2O4 nanoparticlesn(NPs). Because the size and shape of NiGa2O4 are very sensitive to the pH of the precursor, ethylene glycol hasnbeen employed as the solvent, as well as the reduction agent to reducenGO, to avoid using extra surfactants and also to avoid the variationnof pH of the precursor. The obtained NiGa2O4/rGO composite possesses high capacity and long cycle life (2000ncycles, 2 A/g), with NiGa2O4 NPs around 3–4nnm that are uniformly distributed on the rGO surface. Full cell performancenwith LiCoO2 as cathode has also been studied, with thenaverage loss of 0.04% per cycle after 100 cycles (C/2 of LiCoO2). The long cycle life of the composite was ascribed to thenself-healing feature of Ga0 formed during charging.","PeriodicalId":521677,"journal":{"name":"Figshare","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147883778","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}
