The invention discloses a preparation method of a lithium battery negative electrode material Mo2C/NiO-coated GO carbon nanofiber. The preparation method comprises the following steps: S1, weighing nickel oxide, ammonium molybdate tetrahydrate and a solvent, and carrying out ultrasonic treatment; s2, weighing a high-molecular surfactant, adding the high-molecular surfactant into a beaker, and stirring at normal temperature to obtain a required spinning solution; s3, a needle tube is adopted to suck the spinning solution for electrostatic spinning to obtain a precursor, and the precursor is taken down after spinning is completed and dried in a drying oven; s4, carrying out pre-sintering on the dried precursor; s5, carrying out suction filtration on the pre-sintered precursor; and carrying out suction filtration and drying, and then carrying out heat treatment to obtain the required lithium ion battery negative electrode material. According to the preparation method disclosed by the invention, the Mo2C/NiO-coat
