    Publication number: 20220367857
    Abstract: The present application provides a negative electrode material, a preparation method thereof, and a lithium ion battery. The negative electrode material comprises a first graphite core and a composite coating layer coated on the first graphite core. The composite coating layer comprises a second graphite inner layer formed on the surface of the first graphite core and an amorphous carbon outer layer formed on the surface of the second graphite inner layer. The second graphite inner layer is graphite microcrystal. The preparation method comprises: mixing the first graphite and the second graphite and performing the coating treatment to obtain the first graphite coated with the second graphite, wherein the second graphite is graphite microcrystals; and making the first graphite coated with the second graphite, coated with carbon, to obtain the negative electrode material.
