ABSTRACT:
A graphite particle obtained by assembling or binding together a plurality of flat-shaped particles so that the planes of orientation are not parallel to one another, or a graphite particle in which aspect ratio is 5 or less or specific surface area is 8 m2/g or less or the size of crystallite in the direction of c-axis of the crystal is 500 Å or more and the size of crystallite in the direction of plane is 1,000 Å or less as measured by X ray broad angle diffraction, or a graphite particle in which pore volume of the pores having a size falling in a range of 102to 106Å is 0.4 to 2.0 cc/g per weight of graphite particle or pore volume of the pores having a size falling in a range of 1×102to 2×104Å is 0.08 to 0.4 cc/g per weight of graphite particle is suitable for production of negative electrode of lithium secondary battery, and a lithium secondary battery obtained therefrom is excellent in rapid charge-discharge characteristics, cycle characteristics, etc.
