Abstract:
(EN) The present invention relates to a mixed cathode active material comprising lithium manganese oxide expressed by the following [formula 1] and a second cathode active material expressed by the following [formula 2], and to a lithium secondary battery including the mixed cathode active material; [Formula 1] aLi2MnO3·(1-a)LixMO2 where 04-xMn5-2x-yCo3xMyO12 where 04Mn5O12 so that an available SOC section can be broadened by alleviating a sharp output decrease in a low SOC section, and output can also be further improved over the entire SOC section, as compared to the case of using pure Li4Mn5O12.
(FR) La présente invention concerne un matériau actif composite de cathode comprenant de l'oxyde de manganèse lithié représenté par la [formule 1] ci-après et un second matériau actif de cathode and a second cathode active représenté par la [formule 2] ci-après, ainsi qu'une batterie rechargeable au lithium comprenant le matériau actif composite de cathode. [Formule 1] aLi2MnO3·(1-a)LixMO2, où 0 < a < 1, 0,9 ≤ x ≤ 1,2, et M est un, deux ou plusieurs éléments sélectionnés dans le groupe constitué par : Al, Mg, Mn, Ni, Co, Cr, V et Fe ; et [Formule 2] Li4-xMn5-2x-yCo3xMyO12, où 0 < x < 1,5, 0 ≤ y < 0,5, et M est un ou plusieurs éléments de métal de transition. Ledit matériau actif composite de cathode comprend en outre du Li4Mn5O12 riche en Mn et co-dopé de telle façon qu'une section de SOC disponible SOC puisse être élargie par réduction d'une forte chute de sortie dans une section de SOC réduite, et de façon à améliorer la sortie de la totalité de la section de SOC comparativement aux cas d'utilisation de Li4Mn5O12 pur.
(KO) 본 발명은 하기 [화학식 1]로 표시되는 리튬 망간산화물과 하기 [화학식 2]로 표시되는 제2의 양극활물질을 포함하는 혼합 양극활물질 및 이를 포함하는 리튬이차전지에 관한 것이다. [화학식 1] aLi2MnO3·(1-a)LixMO2 상기 [화학식 1]에서, 04-xMn5-2x-yCo3xMyO12 상기 [화학식 2]에서, 04Mn5O12를 추가로 포함함으로써, 저SOC 구간에서의 급격한 출력 저하를 완화시켜 가용 SOC 구간을 넓힘과 동시에, 순수한 Li4Mn5O12를 사용한 경우 대비 전 SOC 구간에 걸쳐 더욱 향상된 출력을 제공할 수 있다.
