description The invention discloses a preparation method of a graphene/nickel dicobalt tetrasulfide electrode material with a sandwich structure, which specifically comprises the following steps: firstly, taking a graphite foil as an anode and a platinum wire as a cathode, carrying out electrochemical stripping, dissolving in deionized water, and carrying out suction filtration on the formed graphene centrifugate to form a film; then NiCl2. 6H2O, CoCl2. 6H2O and urea are mixed, hydrothermal treatment is carried out, and NiCo (OH) powder is obtained; the preparation method comprises the following steps: mixing NiCo (OH) powder, thiourea and H2O, and carrying out hydrothermal reaction to obtain magnetic NiCo2S4; dissolving NiCo2S4 in deionized water, pouring on the formed film, and carrying out suction filtration to form a double-layer film; and pouring the graphene centrifugate on the double-layer membrane, carrying out suction filtration again to form a membrane, and drying. According to the electrode material with the s
