| titleOfInvention | A negative electrode active material composed of natural graphite particles having improved particle strength and a lithium secondary battery comprising the same |
| abstract | The present invention relates to a natural graphite particle having remarkably improved particle strength, including a natural graphite core particle and a surface coating layer for coating the surface of the particle, more specifically, a natural graphite particle having a surface coating layer containing a carbon precursor Strength natural graphite particles having a particle strength of 60 MPa or more. Since the natural graphite particles of the present invention are high-strength particles having a particle strength of more than 60 MPa, crushing or cracking does not occur when they are pressed onto the current collector, so that the electrolyte impregnability of the anode active material can be increased, Can be improved. Therefore, the secondary battery including the natural graphite particles of the present invention as a negative electrode active material has an advantage of being excellent in charging / discharging efficiency, improved lifetime characteristics, and widely used in industry. |
