The invention discloses a preparation method of an anode material of a lithium battery. The method comprises the following steps: A, equally dividing an anode active material and a conductive agent into three equal parts, dividing a binding agent into four parts and dividing a dispersant into four parts, and mixing the first part of binding agent, the first part of dispersant, the first equal part of positive active substance and the first equal part of conductive agent to obtain a first mixed material; B, preparing a second mixed material and a third mixed material; C, mixing the first mixed material, the second mixed material and the third mixed material to obtain an inner core active material; D, covering a layer of inorganic nanometer film on the outer part of the inner core active material to obtain the anode material of the lithium battery. The anode material of the lithium battery, prepared by the invention, has good conductivity and is high in tapping density; moreover, the volume of the prepared battery is large, and scale production demand can be met.
