| titleOfInvention | Method for producing graphite powder for negative electrode material of lithium ion secondary battery |
| abstract | The present invention includes a step of graphitizing a mixture of a carbon raw material powder and a silicon carbide powder, wherein a 90% particle diameter D 90 in a volume-based cumulative particle size distribution by a laser diffraction method of the silicon carbide powder is 1 to 40 μm, and the carbon raw material Content of silicon carbide in the total mass of silicon carbide and silicon carbide (total mass of silicon carbide / mass of carbon raw material and silicon carbide) is 1 to 35% by mass, and volume-based accumulation of silicon carbide powder by laser diffraction method lithium ions values of the ratio of D 50 carbon raw material powder for the 50% particle size D 50 in the particle size distribution (D 50 D 50 of / silicon carbide of the carbon source) is characterized in that it is a 0.40 to 4.0 The present invention relates to a method for producing graphite powder for a secondary battery negative electrode material. According to the production method of the present invention, it is possible to provide a graphite powder for a negative electrode material for a lithium ion secondary battery that is low in cost and has a high capacity, a high density, and a high capacity retention rate. |
