The invention relates to a manufacturing method of a sodium-ion battery negative electrode material. The manufacturing method comprises the following steps of step 1, synthesizing ZIF67; step 2, preparing Fe-ZIF67: a, measuring 200-300ml of deionized water, removing oxygen at a high temperature, cooling the deionized water to a room temperature under argon, adding 650-750mg of Fe(NO3)2.6H2O into the deionized water, stirring to dissolve so as to obtain a mixed solution A, heating the mixed solution A to 38-45 DEG C, and keeping introducing the argon in a whole process; b, weighing 150-200 mg of ZIF67 and dissolving in 20 ml of absolute ethyl alcohol, and acquiring a mixed solution B after ultrasonic treatment; and c, adding the mixed solution B into the mixed solution A, stirring at a constant temperature, cooling to the room temperature, introducing the argon in the whole process, centrifugally collecting precipitates, centrifugally washing with the deionized water, and carrying out vacuum drying to obtain Fe-ZIF67. The ZIF67 is adopted as a precursor, divalent iron ions are used for partially replacing cobalt ions in the ZIF67, a novel metal-organic framework Fe-ZIF67 with coexistence of iron and cobalt is obtained and is served as a sodium-ion battery negative electrode material, and an electrochemical capacity can be effectively increased and cycling stability is enhanced.
