Abstract

Graphite powder having on the surface thereof closed structures in which the terminals of c-plane layers are closed in a loop form, having a density of 100 to 1,500 pcs/um at gap planes among the closed structures in the graphite caxis direction and having preferably a specific surface area of not greater than 1.0 m2/g is produced by graphitizing a carbon material pulverized at a high speed at a controlled number of revolutions for a controlled time before or after carbonization, or subjecting a carbon material pulverized at a controlled number of revolutions for a controlled time before or after carbonization to an oxidation heat-treatment at 600 to 800 ~C after graphitization and then heat-treating the carbon material at a temperature not lower than 800 ~C in an inert gas. The negative electrode of a lithium ion secondary cell comprising this graphite powder has both a high discharge capacity of at least 320 mAh/g and high charge/discharge efficiency of at least 90 %.
