초록
Lithium ion Battery(LIB)의 음극 활물질로써 리튬을 대체하기 위한 노력으로 phenol resin을 탄화시킨 탄소재료를 사용하였다. Phenol resin을 소성하면 축합반응을 일으키면서 탄화되어 무정형 탄소가 된다. 무정형 탄소는 층간거리가 넓어 리튬의 삽입과 탈리가 용이하지만 탄소간의 결합력이 약하여 구조적 붕괴가 일어난다. 이러한 문제를 해결하기 위해 세공형성제로서
For replacing Li metal at Lithium ion Battery(LIB) system, we used carbon powder material which prepared by Pyrolysis of Phenol resin as starting material. It became amorphous carbon by Pyrolysis through it's self condensation by thermal treatment. Amorphous carbon can be doped with Li intercalation and deintercalation because it has wide interlayer. However, it has a problem with structural destroy due to weak carbon-carbon bond. So, we used
