  • Patent number: 11688850
    Abstract: A preparation method of SnO2@Sn coated reduced graphene oxide composite material. By compounding reduced graphene oxide and SnO2, SnO2 undergoes conversion and alloying reactions to form Sn nanoparticles, and the three components have a synergistic effect and good reversibility. Nano SnO2@Sn particles are uniformly distributed on the ultrathin RGO nanosheets. RGO can effectively alleviate volume expansion caused by SnO2 and prevent SnO2@Sn nanoparticles from agglomeration during cycle. The adhesion of SnO2@Sn on RGO can also effectively reduce the repacking of RGO nanosheets, so that the composite material maintains a large surface area during the charge-discharge process, providing sufficient space for the storage of potassium ions. Therefore, the prepared SnO2@Sn coated reduced graphene oxide composite material (SnO2 @Sn@RGO) has excellent electrochemical performance, exhibits excellent cycle performance, rate capability and long-term cycle stability, and has a very ideal first coulomb efficient.
