The invention relates to a preparation method of a graphite sheet surface chemical plating iron-nickel alloy layer. The preparation method comprises the following steps of 1, carrying out degreasing treatment on a graphite sheet; 2, carrying out oxidation treatment on the graphite sheet subjected to degreasing treatment; 3, carrying out the following sensitized treatment on the graphite sheet by utilizing a stannous chloride solution; 4, carrying out activating treatment on the graphite sheet by utilizing a palladium chloride solution; 5, sequentially adding 8-10 parts of C6H5Na3O7.2H2O powder, 4-5 parts of NH4Cl2 powder, 3-6 parts of FeSO4.7H2O powder, 2-3 parts of NiSO4.6H2O powder and 2-4 parts of NaH2PO2.H2O powder into ultra-pure water according to the mass ratio so as to fully dissolve the powder, adopting a NaOH aqueous solution as a pH adjustment solution, and dropwise adding the pH adjustment solution with the pH being controlled in a range of 9-9.5 to prepare a plating solution for surface chemical plating of the graphite sheet; 6, carrying out chemical plating treatment on the graphite sheet subjected to preliminary treatment. The preparation method is convenient in manufacturing and simple in process, and a compact and uniform plating layer with controllable thickness can be obtained on the surface of the graphite sheet.
