Abstract

A new type of Sn@SnO₂@C@MoS₂ composite, composed of Sn@SnO₂@C nanosheets and decorated with MoS₂, exhibits significantly improved electrochemical performance. This composite has excellent long-term cycling stability (841 mA h g⁻¹ at 1.0 A g⁻¹ after 400 cycles) and superior high-rate capability (458.3 mA h g⁻¹ at 10.0 A g⁻¹) due to the strong synergistic effect between the MoS₂ and Sn@C nanosheets.
