The invention provides a preparation method for a three-dimensional classified pore structure graphene electrode material. The method comprises the following steps: 1) preparing metallic oxide/graphene oxide mixed solution; 2) preparing mixed xerogel through a hydrothermal reaction, drying and dehydrating; and 3) preparing the three-dimensional classified pore structure graphene electrode materialthrough high-temperature heat treatment, washing and drying. The provided preparation method for the three-dimensional classified pore structure graphene electrode material is simple in preparation process, and capable of avoiding a defect that a template and an activator are nonuniformly dispersed. Prepared graphene gel is high in reduction degree, stable in physical and chemical properties, andgood in conductivity. Compared with a current graphene electrode material, the three-dimensional classified pore structure graphene electrode material has the advantages of high energy density, highpower density, and good cycle life and rate capability and the like.
