The invention discloses a preparation method of transitional metal oxide/carbon of a lithium ion battery negative material. The method comprises the steps that a metal nitrate is dissolved in an N,N-dimethyl formamide solution and stirred continuously at the room temperature to form a solution A; ethylene diamine tetraacetic acid is dissolved in the N,N-dimethyl formamide solution with triethylamine, and stirred continuously at the room temperature to form a solution B; the solution A is added into the solution B, and stirred continuously at the room temperature to form a precipitate; the precipitate is cleaned and dried in the vacuum to obtain a precursor; and the precursor is burned for 100-150 min at the temperature of 350+/-10 DEG C to obtain a final product. The method to prepare thetransitional metal oxide/carbon is simple in steps, and convenient for industrial large-scale production, particles of the synthesis product are uniform and fine, and the circulation capacity and electrochemical performance of the material are ensured.
