Negative electrode active material for secondary battery, secondary battery including the same, and manufacturing method thereof |
| abstract |
An object of the present invention is to provide a carbon material-based negative electrode active material having optimized particle size distribution and volume density characteristics, and a method for producing the same. The present invention relates to a negative electrode active material for a secondary battery, a secondary battery including the same, and a method for manufacturing the same. The negative electrode active material for a secondary battery according to the present invention has a part of or all of the edge of the core carbon material having a particle form coated with a coating carbon material made of a carbide layer, and d 1 and d of PSD (Particle Size Distribution). The max is 0.5 μm or more and 60 μm or less, respectively, and the volume density is 1.0 to 1.3 g / cm 3 . If the negative electrode of the secondary battery is manufactured using the negative electrode active material for the secondary battery according to the present invention, the processability and the press-bonding property are improved, and the discharge capacity and efficiency of the secondary battery and the discharge capacity maintenance rate in the long-term cycle are improved. Can be improved. [Selection figure] None |
