Abstract:
The present invention relates to a method for producing a graphite-containing carbon powder for a negative electrode of a lithium ion secondary battery having a high undersize yield and a high tapping density, which does not need pulverization treatment after heat treatment. The method comprises a process of forming a carbon coating on the surface of the carbide particles to obtain a carbon-coated raw material; a process of mixing the carbon-coated raw material and a carbon material to obtain a mixed raw material; and a heat treatment process of heating the mixed raw material to 2,000° C. or more to thermally decompose the carbide. Using the graphite-containing carbon powder according to the method of the present invention makes it possible to efficiently obtain a carbon material for a battery electrode, an electrode comprising the carbon material, and a secondary battery having the electrode.

Claim (Index 11):
An electrode containing the carbon material for a battery electrode according to  claim 9  which serves as at least part of an electrode active material.
