| titleOfInvention | Manufacturing method of graphite powder |
| abstract | PROBLEM TO BE SOLVED: To provide graphite suitable for a negative electrode material of a lithium ion secondary battery, showing a high discharge capacity of 340 mAh / g or more and a high charge and discharge efficiency of 80% or more, preferably 90% or more. Produces powder in a stable and relatively low cost. SOLUTION: The free carbon content is 0.1% by mass or less, Tar or pitch having a toluene-insoluble content of 5% by mass or less in the presence of 1 to 6% by mass of a nitrating agent at 250 to 400 ° C. To a temperature of 400 to 600 ° C. and then heat treated at a temperature in the range of 400 to 600 ° C. to form bulk mesophase carbon, This is carbonized and ground. Add resin to the obtained carbonized powder. (Eg, novolak type phenolic resin), carbonize the resin in some cases, and then graphitize. |
