Abstract: The invention provides an anode material for lithium ion secondary battery using a coated graphite powder as a raw material, which is coated thermoplastic resin of a carbonization yield of ?20 wt % in a proportion of ?10 parts by weight the carbonized material per 100 parts by weight graphite powder. Coating with thermoplastic resin increases the accumulative pore volume by ?5%, relative to the uncoated powder, and results in pore sizes of 0.012-40 ?m via mercury porosimeter method. Calculated with the BJH method as viewed from desorption isotherm, the coated graphite powder has a mesopore volume ?0.01 cc/g or ?60% of the pore volume of the uncoated graphite powder. This coated powder also has an average particle size ranging from 10-50 ?m measured by a laser-scattering-particle-size-distribution measuring device, and a standard deviation to the average particle size (?/D) ratio of ?0.02.

Abstract: Since the dense and high purity pyrolytic-carbon-coated layer is formed with a thickness of 10-100 &mgr;m on the surface of the C/C composite, even when metallic impurities of the inside C/C composite are 5-100 ppm in ash content, similar effects to those of a known crucible made of the C/C composite whose inside was subjected to high purification can be produced to achieve full applicability to the structural elements of the CZ apparatus. Also, since the process time required or the C/C composite itself to be subjected to the high purification can be shortened, the effect of reducing the manufacturing costs considerably can be obtained.
