description The invention relates to a preparation method for a negative electrode material of a lithium ion battery. The preparation method comprises the steps of performing uniform ultrasonic dispersion on graphene oxide (GO), and separately adding a sodium dodecyl sulfate (SDS) water solution and phenylamine to mix and to perform ultrasonic processing to form a stable and uniform mixed solution; stirring in an ice-water bath and adding ammonium persulfate (APS) which is acidified by hydrochloric acid in a dropwise manner, and continuing to stir in the ice-water bat for 12h to obtain a black green solution, performing centrifuging and water washing on the black green solution to obtain a gel-shaped material; ultrasonically dispersing the gel-shaped material into a hydrochloric acid solution, and adding tetrabutyl orthotitanate (TBOT) into the solution in a dropwise manner and continuing to perform ultrasonic processing; and finally, stirring at the room temperature for 1h, performing hydrothermal treatment at a tempera
