Antimony Nanorod Encapsulated in Cross-Linked Carbon for High-Performance Sodium Ion Battery Anodes.

Antimony-(Sb)-based materials have been considered as one of promising anodes for sodium ion batteries (SIBs) owing to their high theoretical capacities and appropriate sodium inserting potentials. So far, the reported energy density and cycling stability of the Sb-based anodes for SIBs are quite li... Full description

description: Antimony-(Sb)-based materials have been considered as one of promising anodes for sodium ion batteries (SIBs) owing to their high theoretical capacities and appropriate sodium inserting potentials. So far, the reported energy density and cycling stability of the Sb-based anodes for SIBs are quite limited and need to be significantly improved. Here, we develop a novel Sb/C hybrid encapsulating the Sb nanorods into highly conductive N and S codoped carbon (Sb@(N, S–C)) frameworks. As an anode for SIBs, the Sb@(N, S–C) hybrid maintains high reversible capacities of 621.1 mAh g–1 at 100 mA g–1 after 150 cycles, and 390.8 mAh g–1 at 1 A g–1 after 1000 cycles. At higher current densities of 2, 5, and 10 A g–1, the Sb@(N, S–C) hybrid also can display high reversible capacities of 534.4, 430.8, and 374.7 mAh g–1, respectively. Such impressive sodium storage properties are mainly attributed to the unique cross-linked carbon networks providing highly conductive frameworks for fast transfer of ions and electrons, alleviating the volume expansion and preventing the agglomeration of Sb nanorods during the cycling.
