초록
전기이중층 캐패시터의 성능향상을 위한 전극물질로서 resorcinol-formaldehyde수지를 탄소원으로 사용하여 meso-pore 비율 52∼64%의 기공특성을 지니며 직경 2∼10 μm의 미세구형 활성탄을 제조하였다. 이 활성탄을 전기이중층에 적용한 결과, meso-pore구조의 미세구형활성탄은 전하전달저항의 저감 및 충방전율 수용능력 향상에 효과적인 영향을 나타내어 전기이중층 캐패시터의 성능향상을 위한 효과적인 전극물질이 될 수 있음을 확인할 수 있었다.
A micro-spherical activated carbon with meso-pore structure of 52∼64% and particle diameter of 2∼10 μm was prepared for the improvement electrochemical performance of activated carbon as electrode material for electric double layer capacitor. Resorcinol-formaldehyde resin was used as a carbon source in this preparation. According to electrochemical analysis of EDLC using this activated a carbon with showing effects to reduce charge transfer resistance and to increase rate capability, it was found out that micro-spherical activated carbon could be a good method as well as a material for enhancing the performance of electric double layer capacitor.
