Blooming flower like BiOBr decorated RGO nanocomposite as advanced electrode material for high performance supercapattery applications

Abstract

The present work deals with a synthesis and characterization of bismuth oxybromide decorated reduced graphene oxide (BiOBr/RGO) nanocomposite as working electrode for supercapattery applications. where solvothermal method was adopted for the preparation of BiOBr/RGO nanocomposite. The prepared BiOBr depicts blooming flower-like microspheres and the presence of voids between petals could enable more adsorption of electrolyte ions and also act as conductive channels for easy ion diffusion. Further, the addition of GO with BiOBr resulted in an unfurling flower like morphology for BiOBr/RGO nanocomposite. The BiOBr/RGO (BiOBr – 3 wt% of GO) nanocomposite exhibits supreme specific capacity (Cs) of 3254 C/g at 1 A/g, energy density of 207 Wh/kg at 1 A/g and cyclic stability of 1000 cycles with a capacity retention rate of 97%. These outstanding electrochemical performances suggest that the prepared BiOBr/RGO nanocomposite may serve as a promising working electrode for supercapattery applications in the near future.
