The invention discloses a three-dimensional cross-linked structure SnSe/3D r-GO composite material and a preparation method and application thereof. A simple solvothermal method is used to combine SnSe and three-dimensional graphene to prepare a three-dimensional glue-linked structure SnSe/3Dr-GO The composite material has mild reaction conditions, simple experimental equipment, and easy implementation. The three-dimensional graphene provides space for the volume expansion of the tin selenide alloy at the electrode, which effectively suppresses the volume expansion caused by the alloy negative electrode material and improves the battery capacity. , in electrochemical energy storage, especially as a potassium ion battery anode material can show good performance. |
