  • A facile one-step strategy involving the reaction of antimony chloride with thioacetamide at room temperature is successfully developed for the synthesis of strongly coupled amorphous Sb2S3 spheres and carbon nanotubes (CNTs). Benefitting from the unique amorphous structure and its strongly coupled effect with the conductive network of CNTs, this hybrid electrode (Sb2S3@CNTs) exhibits remarkable sodium and lithium storage properties with high capacity, good cyclability and prominent rate capability. For sodium storage, a high capacity of 814 mAh·g-1 at 50 mA·g-1 is delivered by the electrode, and a capacity of 732 mAh·g-1 can still be obtained after 110 cycles. Even up to 2000 mA·g-1, a specific capacity of 584 mAh·g-1 can be achieved. For lithium storage, the electrode exhibits a high capacity of 1136 and 704 mAh·g-1 at 0.05 and 2 A·g-1, respectively. And the cell holds a capacity of 1104 mAh·g-1 under 50 mA·g-1 over 110 cycles. The simple preparation approach, and remarkable electrochemical properties make the Sb2S3@CNTs electrode a promising anode for both sodium-ion batteries (SIBs) and lithium-ion batteries (LIBs).
