SnSe/3D r-GO composite material with three-dimensional cross-linked structure as well as preparation method and application of SnSe/3D r-GO composite material

The invention discloses a three-dimensional cross-linked structure SnSe/3D r-GO composite material and a preparation method and application thereof.SnSe and three-dimensional graphene are combined through a simple solvothermal method, the three-dimensional cross-linked structure SnSe/3D r-GO composite material is prepared, reaction conditions are mild, experimental equipment is simple and easy to implement, and the three-dimensional cross-linked structure SnSe/3D r-GO composite material is suitable for industrial production. The three-dimensional graphene provides a space for volume expansion of the tin selenide alloy in the electrode, the problem of volume expansion caused by an alloy negative electrode material is effectively inhibited, the capacity of the battery is improved, and the three-dimensional graphene can show relatively good performance in the aspect of electrochemical energy storage, especially as a negative electrode material of a potassium ion battery. 本发明公开了一种三维交联结构SnSe/3D r-GO复合材料及其制备方法和应用，利
