The invention discloses a preparation method of a through-hole type lithium battery negative electrode material, belonging to the technical field of new energy materials. At first, that gelatin is dissolve in glycerol, then titanate and silicate are added, aft heating and stirring reaction for 3-5h, the gelatin is concentrated unde reduced pressure, the residual glycerol is removed, and the gelatin is cooled to obtain a refined concentrate; 3 to 5 hour after that refine concentrate and the sulfuric acid solution are mixed, the hydrothermal reaction is carried out, the material is discharged, is and dried to obtain a hydrothermal carbonized material. Then the hydrothermal carbonized material is dispersed in water, nanometer magnesium powder, nanometer iron powder and sodium fluoride are added, and after ultrasonic impregnation, the hydrothermal carbonized material is filtered and dried to obtain the impregnated hydrothermal carbonized material. The impregnated hydrothermal carbonized material is transferred into a vacuum furnace, the temperature is programmed to be 1480-1500 DEG C, the reaction temperature is preserved and vacuum reacted, then the material is cooled, discharged, washed with dilute hydrochloric acid, washed with water and dried to obtain a through-hole type lithium battery negative electrode material. The through-hole type lithium battery negative electrode material obtained by the invention has excellent cycle performance.
