▎ 摘　　要

We herein reported the design and facile synthesis of hierarchical graphene nanosheets/vanadium oxide (GNS/VOx) structures by creatively using the conventional and most convenient spin-coating approach. This traditional method can easily get the layer-by-layer structure and push forward the practical utilisation of the hierarchical structure in sodium-ion batteries. When used as the cathode for sodium-ion batteries, such hierarchical structures can greatly enhance the electrode cycle stability and provide high capacities in contrast with previous cases of single-phase vanadium oxides.
