The present invention consists of a carbon powder having a homogeneous structure prepared by attaching and / or penetrating an organic compound as a raw material of a polymer to carbonaceous particles, and then polymerizing the organic compound, followed by heat treatment at a temperature of 1,800 to 3,300 ° C. The present invention relates to a carbon material for forming a battery electrode having a substantially uniform structure in which a graphite crystal structure region and an amorphous structure region are dispersed throughout the particle from the surface of the particle to the central portion thereof. By using this material, a battery having a high discharge capacity, a low irreversible capacity, and excellent clon efficiency and excellent cycle characteristics can be produced. |
