METHOD FOR MANUFACTURING NEGATIVE ELECTRODE ACTIVE MATERIAL FOR RECHARGEABLE LITHIUM BATTERY AND RECHARGEABLE LITHIUM BATTERY INCLUDING THE SAME
Presented is a method for manufacturing a negative electrode active material having high discharge capacity, high charge/discharge efficiency, and excellent high output characteristics and having a small volume change during charging/discharging. According to one embodiment of the present invention, the method comprises the steps of: pulverizing a carbon raw material containing 4 to 10% by weight of volatile matter to manufacture primary particles; mixing the primary particles with a binder to manufacture secondary particles; and graphitizing the secondary particles to manufacture graphite.
높은 방전 용량, 높은 충방전 효율 및 우수한 고출력 특성, 충방전 중 체적 변화가 작은 음극 활물질의 제조 방법을 제시한다. 본 발명의 일 구현예에 의한 리튬 이차 전지용 음극 활물질의 제조 방법은 휘발분을 4 내지 10 중량% 포함하는 탄소 원료를 분쇄하여 1차 입자를 제조하는 단계; 1차 입자를 바인더와 혼합하여 2차 입자를 제조하는 단계; 및 2차 입자를 흑연화하여 흑연재를 제조하는 단계를 포함한다.
