Summary:The invention relates to a preparation method of a high-strength graphite electrode. The preparation method comprises the following steps: (1) preparing a chromium trichloride solution; (2) preparing a graphene mixed solution; (3) preparing Cr-COF (at) rGO; (4) preparing Ir/Cr-COF (at) rGO; (5) mixing graphite powder, polyethylene glycol and deionized water, then adding Ir/Cr-COF (at) rGO, uniformly stirring again, and then drying in a drying oven to obtain a composite precursor; and (6) sintering the composite precursor in a graphite furnace, and cooling to room temperature to obtain the graphite electrode material. The graphite electrode material is prepared by adopting the modified graphene to reinforce the graphite. Wherein the modified graphene is Ir/Cr-COF (at) rGO, the modified graphene is compounded with graphite to prepare the graphite electrode material, the strength is relatively high, and the specific capacity and the stability are enhanced to a certain extent. 本发明涉及一种高强度石墨电极的制备方法，包括以下步骤：(1)制备三氯化铬
