Porous capacitor electrode material

The invention discloses a porous capacitor electrode material. The method comprises the following steps: S1, preparing a front material of graphene; s2, adding raw materials, and carrying out mixing and grinding treatment; s3, carrying out heating carbonization treatment on the material after grinding treatment; s4, the material obtained after carbonization treatment is cleaned; s5, the cleaned carbon material is subjected to casting molding; s6, preparing an electrode plate; according to the method, the coal pitch is adopted for preparing a pre-material of graphene, the resource cost is effectively saved, ammonium phosphate can be effectively mixed, the coal pitch and the ammonium phosphate are synchronously heated, the ammonium phosphate and carbon are effectively mixed, preparation of N/P co-doped porous graphene is completed, and the method is suitable for industrial production. And when the electrode plate is prepared, secondary crushing and filtering treatment is adopted, so that the purity of the elect
