Abstract

본 발명은 리튬이차전지 양극 소재 계면 안정성 개선을 위한 유기 첨가제 코팅 방법에 관한 것으로, 더욱 상세하게는 고용량 High-Ni계 LiNixCoyMnzO2(NCM) 양극 활물질 표면에 설포네이트계 양친매성 유기 전구체를 습식-코팅한 후 열처리하여 인위적인 CEI(Cathode electrolyte interphase) 층을 고정화시킴으로써, 전해액 분해를 효과적으로 억제하여 원치 않는 표면 부반응을 감소시키고 양극 소재의 계면 안정성을 크게 증대시키며 그 결과 이를 채용한 전지의 전기화학적 성능을 개선할 수 있는, 리튬이차전지 양극 소재 계면 안정성 개선을 위한 유기 첨가제 코팅 방법, 이에 따라 인공 CEI 층이 형성된 양극 소재, 및 이를 포함하는 고성능 리튬이차전지에 관한 것이다.
