Exploring novel electrode materials with high rate capability and outstanding cycling stability is an urgent issue for sodium-ion batteries (SIBs). Herein, Bi2S3 nanorods anchoring on reduced graphene oxide (Bi2S3@rGO composite) are designed and synthesized for sodium storage applications. With the contributions from the unique structure, the surface C-S bonds on rGO, and the synergetic effects from the components, the composite delivers remarkable electrochemical performances. The results indicate that the strategy of chemically constructing a composite structure can be very promising for advanced electrodes of SIBs.
