▎ 摘  要

Metal molybdates have attracted considerable attention as promising anode materials for sodium ion batteries (SIBs) due to their high theoretical specific capacity and excellent electrochemical performance. However, their low rate capacity and rapid capacity attenuation hinder their application in SIBs. Here, amorphous NiMoO4/graphene nanofibers were prepared via an electrospinning method. The electrochemical performance of NiMoO4 was first reported as the anode for SIBs. Amazingly, the amorphous NiMoO4/graphene delivered an outstanding specific capacity of 260 mAh g(-1) after 100 cycles at 100 mA g(-1) at a potential range from 0.01-2.7 V and an excellent rate performance of 160 mAh g(-1) at 1 A g(-1). The superior electrochemical properties of amorphous NiMoO4 can be ascribed to its amorphous structure and reduced diffusion distance, and the strong synergy of NiMoO4 and graphene.
