Abrégé
(KO)
본 발명은 셀 성능 측정방법에 관한 것으로, 본 발명에 따른 셀 성능 측정방법은, 제1 전극탭을 구비하는 제1 전극, 분리막, 및 제2 전극탭을 구비하는 제2 전극이 교대로 적층되어 접합된 단위셀의 성능을 측정하는 방법으로, 상기 단위셀의 최외각에서 상기 제1 전극과 대면되는 측에 상기 제2 전극과 동일 극성을 갖고, 제3 전극탭을 구비하는 대면 전극을 상기 분리막을 사이에두고 더 적층시키는 추가 적층단계, 및 상기 제1 전극에 구비된 제1 전극탭과 상기 대면 전극에 구비된 제3 전극탭 사이를 전기적으로 연결하여 상기 제1 전극 및 상기 대면 전극 사이의 계면간 성능차이를 측정하는 외측 계면 분석단계를 포함한다.
