Metal molybdate nanostructures show great potential as electrode materials for sodium ion batteries.
The FeMoO4/graphene composite anode exhibits high specific capacity, good cycling stability, and acceptable rate capability.
After 1000 cycles, the composite anode shows stable cycling behavior with nearly 100% capacity retention.
Metal molybdate nanostructures hold great promise as better performing electrode material for sodium ion batteries. In this work, graphene encapsulated FeMoO4 nanorods have been prepared using a simple, facile, scalable and low-cost technique. The uniform distribution of homogeneous and well-defined FeMoO4 nanorods over graphene sheets is apparently evidenced by HR-TEM. The exclusively designed architecture effectively mitigates the severe volume changes associated with the conversion mechanism driven prolonged cycling along with the improved electronic conductivity of the electrode. As a result, FeMoO4/graphene composite anode exploited for the first time as an anode for SIBs exhibits excellent electrochemical performance in terms of high specific capacity (294 mAh g(-1) at 50 mA g(-1) after 100 cycles), good cycling stability (83% after 100 cycles) and an acceptable rate capability (110 mAh g(-1) at 1000 mA g(-1)). More importantly, FeMoO4/Graphene composite anode demonstrates stable cycling behavior with almost 100% capacity retention even after 1000 cycles at 0.5 A g(-1), which implies that the FeMoO4/G composite anode qualifies itself as a high performing anode material for sodium ion battery applications.
