초록

리튬이온 이차전지에 사용되는 탄소부극의 성능을 향상시키기 위하여 결정성계 탄소재료와 비결정성계 탄소재료의 혼합비율에 따른 조합형 탄소전극을 제조하였으며, 이들의 전기화학적 특성과 충방전 특성을 조사하여 조합비율에 따른 리튬의 삽입과 탈삽입 반응기구 및 최적의 조합조건을 찾고자 하였다. 탄소전극은 결정성계 탄소재료인 natural graphite와 700℃에서 1시간 동안 열처리된 비결정성계 탄소재료인 petroleum cokes를 사용하였다. 조합비에 따라 제조된 조합형 탄소전극은 두 가지 형태의 탄소재료가 갖는 전극특성을 지니며 50:50wt%로 조합하였을 때 가장 우수한 전기화학적 특성과 충·방전 특성을 나타냈다.

This study was investigated to improve peformance of carbon negative electrode for lithium ion secondary battery. The carbon electrode was prepared by mixing with graphitic carbon material, natural graphite, and nongraphitic carbon material, petroleum cokes, which was heat-treated at 700℃ for l hour. Its electrochemical and charge-discharge characteristics were tested according to mixing ratio of different two types of carbon material. The carbon electrode prepared with various mixing ratio showed both charateristcs of two different types of carbon materials and the best characteristics as carbon electrode was demonstrated at mixing ratio of 1:1.
