More Information
Summary:The present embodiments relate to a graphite-based negative electrode material, a manufacturing method thereof, a negative electrode including the same, and a lithium secondary battery including the same. According to one embodiment, the graphite-based anode material comprises: a graphite oxide obtained by oxidizing a surface of first graphite; and a graphite coating material including second graphite and low-crystalline carbon located on a surface of the second graphite. The graphite coating material may be 1/9 to 1/3 of the graphite oxide. 본 실시예들은, 흑연계 음극재, 이의 제조 방법, 이를 포함하는 음극, 및 이를 포함하는 리튬 이차 전지에 관한 것이다. 일 실시예에 따른 흑연계 음극재는 제1 흑연의 표면을 산화시킨 흑연 산화물; 및 제2 흑연과 상기 제2 흑연 표면에 위치하는 저결정성 탄소를 포함하는 흑연 코팅물을 포함하고, 상기 흑연 산화물에 대한 상기 흑연 코팅물은 1/9 내지 1/3일 수 있다.
