摘要

•Novel HCNFs@SnS2 anode materials were first synthesized by a simple and controllable two-step method.•HCNFs@SnS2 composite exhibits the excellent reversible capacity of 901.6 mAh/g, about seven times as many as HCNFs@SnO2.•High performance of HCNFs@SnS2 benefits from the synergistic contribution between coiled carbon and SnS2 nanoparticles.
