Abstract: front page image
(EN)The present invention relates to a method for manufacturing a cathode active material for a lithium secondary battery and, more particularly, to a method for manufacturing a cathode active material for a lithium secondary battery, comprising: generating manganese complex deposit by restoring and depositing manganese and heterogeneous metal elements from a mixed solution containing a manganese compound and a heterogeneous metal element compound; and generating lithium manganese complex oxide by mixing the manganese complex deposit with a lithium-contained metal compound and firing the mixture at 400 to 750 ºC. According to the present invention, a cathode active material for a lithium secondary battery in which vanadium is effectively doped into lithium manganese complex oxide can be manufactured, and the use thereof enables the production of a lithium secondary battery having improved capacity and remarkably improved charging and discharging efficiency.
(FR)La présente invention a trait à un procédé de fabrication d'une matière active de cathode destinée à une batterie rechargeable au lithium et, plus particulièrement, à un procédé de fabrication d'une matière active de cathode destinée à une batterie rechargeable au lithium, comprenant les étapes consistant : à générer un dépôt complexe de manganèse en restaurant et en déposant du manganèse et des éléments métalliques hétérogènes à partir d'une solution mixte contenant un composé de manganèse et un composé d'élément métallique hétérogène ; et à générer un oxyde complexe de lithium-manganèse en mélangeant le dépôt complexe de manganèse avec un composé métallique contenant du lithium et en chauffant le mélange de 400 à 750 ºC. Selon la présente invention, il est possible de fabriquer une matière active de cathode destinée à une batterie rechargeable au lithium dans laquelle du vanadium est dopé de façon efficace en oxyde complexe de lithium-manganèse, et son utilisation permet de produire une batterie rechargeable au lithium qui est dotée d'une capacité améliorée et d'une efficacité de charge et de décharge remarquablement améliorée.
(KO)본 발명은 리튬 이차전지용 양극 활물질의 제조 방법에 관한 것으로, 특히, 망간 화합물 및 이종 금속 원소 화합물을 포함하는 혼합 용액으로부터, 망간과 상기 이종 금속 원소를 환원 침전시켜 망간 복합 침전물을 생성시킨 후에, 리튬 함유한 금속 화합물과 혼합하여 400 내지 750 ℃의 조건 하에서 소성시켜 리튬 망간 복합 산화물 생성시키는 것을 특징으로 하는 리튬 이차전지용 양극 활물질의 제조 방법에 관한 것이다. 본 발명에 따르면, 리튬 망간 복합 산화물에 바나듐을 효과적으로 도핑시킨 리튬 이차전지용 양극활물질을 제조할 수 있으며, 이를 이용하면 용량이 개선되고 충방전 효율이 현저히 향상된 리튬 이차전지를 생산할 수 있다.
