As supercapacitor electrodes, the C@Ni₃S₂@MoS₂ nanorods deliver a specific capacitance as high as 1544 F g⁻¹ at a current density of 2 A g⁻¹ with excellent cycling stability (retaining 92.8% of the capacitance after 2000 cycles at a current density of 20 A g⁻¹). The C/Ni nanorods as the backbone played crucial roles in enhancing the rate performance of the device, in the meanwhile, interconnected MoS₂ nanosheets on the shell provided numerous accessible surfaces and contacts with the electrolyte. Our work demonstrated an effective design of robust hierarchical double core/shell nanostructures, which could provide a general and promising approach to fabricate high-performance materials for energy storage applications.enThis journal is © The Royal Society of Chemistry 2016Journal article003007992110.1039/c5ta08714g2-s2.0-84955312394235894
