文摘

Due to the high theoretical capacity of 946 mAh g^鈥?, Sb₂S₃ can be employed as promising electrode material for sodium-ion batteries (SIBs). Herein, the sodium storage behaviors of one-dimensional (1D) Sb₂S₃-based materials (Sb₂S₃ and Sb₂S₃@C rods) are successfully studied for the first time, displaying good cyclability and rate capability owing to their unique morphology and structure. Specifically, the Sb₂S₃@C rods electrode presents greatly enhanced electrochemical properties, resulting from the introduction of thin carbon layers which can effectively alleviate the strain caused by the large volume change and simultaneously improve the conductivity of electrode during cycling. At a current density of 100 mA g^鈥?, it delivers a high capacity of 699.1 mAh g^鈥? after 100 cycles, which corresponds to 95.7% of the initial reversible capacity. Even at a high current density of 3200 mA g^鈥?, the capacity can still reach 429 mAh g^鈥?. This achievement may be a significant exploration for develpoing novel 1D Sb-based materials or metal sulfide SIBs anodes.
