Patent ID: 8802297

Claim:
A graphite particle for use in forming a negative electrode for a lithium secondary battery, comprising a plurality of flat-shaped particles bound together so that planes of orientation of flat-shaped particles do not become parallel to one another, wherein the flat-shaped particles have at least one of the following characteristics: an aspect ratio of 5 or less; a specific surface area of 8 m 2 /g or less; a crystallite size in a direction of a c-axis of the crystal of 500 Å or more as measured by X ray broad angle diffraction; a crystallite size in a direction of a plane of the crystal of 1,000 Å or less as measured by X ray broad angle diffraction; a pore volume of pores having a size falling in the range of 10 2 to 10 6 Å of the particles of 0.4 to 2.0 cc/g per weight of the particles; and a pore volume of pores having a size falling in a range of 1×10 2 to 2×10 4 Å of the particles of 0.08 to 0.4 cc/g per weight of the particles.
