▎ 摘　　要

The dense VS4 nanorods laterally anchored on the bilateral surface of reduced graphene oxide nanosheets (VS4@rGO) are successfully constructed through a simple hydrothermal method. Benefiting from the synergistic effect of VS4 nanorods with abundant energy storage sites, rGO nanosheets with high electrical conductivity and their interfacial lattice interaction and V-C bond, VS4@rGO sodium-ion battery (SIB) anode shows the superior rate capability with the specific capacity of 264, 176 and 114 mAh/g at 1, 5 and 10 A/g after 1000 cycles, respectively. The work provides a high-performance anode material for SIB and a new design idea for metal sulfides/carbon heterostructures in energy storage field.
