슈퍼커패시터: 원리 및 재료

본 교재의 전체적인 구성은 많은 고민과 토론을 거쳐 전기이중층 커패시터에서 일어나는 반응의 기초를 다루고 전극 재료, 전해질, 집전체, 바인더, 분리막 등 핵심소재에 대한 구조와 성질 및 이들의 반응 등을 다루었으며 이중 고분자공학 전공자들의 심층 학습을 유도하기 위하여 성능 평가, 전극재료, 전해질 등의 내용을 최근 연구동향과 더불어 추가로 제시하였다.

에너지 저장 및 변환 기술은 최근 세계적으로 주목받고 있는 전기자동차와 일상생활, 우주산업 등 방대한 영역에서 사용하고 있는 핵심기술로써 에너지 저장 및 변환 기술에 대한 기대는 미래의 국가 경쟁력이라고 단호히 말할 수 있는 바이다. 그러나 에너지 저장 및 변환 기술의 큰 축인 슈퍼커패시터의 경우 미국, 일본 등 선진국들에서 간혹 출판되는 경우는 있지만, 내용이 출판된 연구 논문들의 요약이 대부분이어서 피상적인 경우가 많은 단점이 있고 안타깝게도 기초 원리나 응용 등에 대한 체계적이고 합리적인 교재는 국내에서는 찾아볼 수 없는 실정이다.
본 교재의 전체적인 구성은 많은 고민과 토론을 거쳐 서론에서 슈퍼커패시터에서 일어나는 반응의 기초를 다루고 본론에서는 전극 재료, 전해질, 집전체, 바인더, 분리막 등 핵심 소재에 대한 구조와 성질 및 이들의 반응 등을 다루었으며 이중 고분자공학 전공자들의 심층 학습을 유도하기 위하여 성능 평가, 전극 재료, 전해질 등에 대한 내용을 기술하였다.
본 교재는 슈퍼커패시터의 기초 이론 및 재료에 대하여 독자들에게 이해를 증진하기 위한 목적으로 기술하여 슈퍼커패시터에 대한 흥미를 느낄 수 있도록 하였다.
끝으로 본 교재를 출판하는 데 있어 미흡한 부분은 많은 지도를 받아 수정 및 보완해 나가도록 할 예정이며, 본 교재가 출판되기까지 수고해주신 여러분들에게 심심한 사의를 표하는 바입니다.
