Abstract
Provided in the present application is an anode active material, in which a preparation method of the anode active material includes steps as follows: in step 1, mixing graphite particles, sodium tetraborate and amorphous carbon, pulping with mixed particles prepared therefrom, thereby obtaining a mixed slurry, in which a feeding amount of materials mentioned above meets as follows: a mass of the graphite particles:a mass of the amorphous carbon=2~4:6~8, a mass of the sodium tetraborate:a mass of the graphite particles=0.07~0.12:1, and the graphite particles include synthetic graphite; in step 2, spray-drying the mixed slurry, and solid particles obtained therefrom are used as a precursor; and in step 3, heating the precursor for 18~34 hours at 2000~3000° C. so as to prepare and obtain the anode active material.
