Self-assembly of antimony sulfide nanowires on three-dimensional reduced GO with superior electrochemical lithium storage performances

Abstract

The three-dimensional Sb2S3 nanowires/reduced graphene oxide (SBSWs/rGO) was prepared as an anode for lithium storage by self-assembling SBSWs on 3D rGO framework. SBSWs/rGO shows the perfect rate capability (505 mAh g−1 at 3 A g−1) and long cycle stability (697 mAh g−1 after 100 cycles at 100 mA g−1). The 3D rGO framework has good structural stability, which can provide a free space towards shortening lithium ions diffusion paths and accommodating the volume change of SBSWs. The rGO sheets with high electrical conductivity promote electron transfer in composites to improve rate performances.
