Graphite powder for negative electrode of lithium ion secondary battery and method for producing the same |
| abstract |
(57) [Summary] [Problem] A negative electrode of a lithium ion secondary battery having a small specific surface area, a bulk density of 1.35 g / cm 3 or more, excellent filling properties, and excellent discharge capacity and charge / discharge efficiency using a mesophase as a raw material. To obtain a graphite powder. SOLUTION: 75 to 98% by weight of graphite powder obtained by carbonizing and graphitizing a bulk mesophase powder having an average particle diameter of 20 to 40 μm. And graphite powder obtained by carbonizing or graphitizing a mesophase spheroid having an average particle size of 10 μm or less and carbonized or graphitized. |
