    摘要: In a method of fabricating graphite flakes applied in a graphite nanomaterial, mesophase pitch and an organic solvent are used to produce a carbon precursor slurry, and the carbon precursor slurry is coated by a scraper to produce the graphite flakes. Since the method of using natural graphite as a raw material in production requires a number of purification processes to manufacture an expanded graphite powder before the graphite flakes can be produced, and thus the fabricating cost is very high, and other high-priced materials such as polyimide (PI) or graphene also will increase the total cost.

    摘要: The present invention relates to a negative electrode for lithium ion rechargeable battery and a manufacturing method thereof. The negative electrode comprises at least one vermicular graphite and at least one pitch, wherein the vermicular graphite is fabricated by way of thermally treating an expandable graphite powder, and the pitch is adsorbed in the pores of the vermicular graphite. In the present invention, the pitch adsorbed in the vermicular graphite would be carbonized and graphitized, such that a composite graphite having multi-layer flake graphite is formed, and the composite graphite is further pulverized to a composite graphite powder. Moreover, the manufacturing method of the present invention can be used for fabricating the negative electrode for lithium ion rechargeable battery under the conditions of reducing manufacturing cost and solvent usage, so as to protect the environment from the manufacturing process pollution.
