Sn-interspersed MoS2/C (Snsingle bondMoS2/C) nanosheets were prepared via a two-step hydrothermal method. The modification of the MoS2/C nanosheets using Sn was designed to improve their electrochemical performance. When used as anodes for sodium ion batteries (SIBs), the electrodes exhibited an initial capacity of 536 mA h g−1and maintained a capacity of 431 mA h g−1after 90 cycles at 0.1 A g−1. In potassium ion batteries (KIBs), the electrodes also delivered a discharge capacity of 290 mA h g−1at 0.1 A g−1and a high rate capacity of 123 mA h g−1at 0.8 A g−1. Thus, Snsingle bondMoS2/C nanosheets have potential applications in novel rechargeable batteries.
