A　composite　of　F-doped　TiO2(B)　and　reduced　graphene　oxide　(F-TiO2(B)/rGO)　was　successfully　synthesized　via　a　one-step　hydrothermal　route.　It　was　found　that　the　introduction　of　F　ions　in　the　synthetic　process　has　led　to　the　uniform　dispersion　of　TiO2(B)　on　rGO　nanosheets.　The　F　ions　have　also　been　doped　into　the　lattice　of　TiO2(B),　which　greatly　improved　the　conductivity　of　the　materials.　Consequently,　this　composite　delivered　a　large　capacity　of　249.4　mA　h　g−1　at　0.2　A/g.　It　also　demonstrated　a　capacity　of　203.1　mA　h　g−1　and　an　excellent　capacity　retention　of　96%　after　500　cycles　even　at　a　high　current　density　of　2　A/g.　©　2023　Elsevier　Inc.
