Title (EN) POSITIVE ELECTRODE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERY, COMPRISING LITHIUM COBALT OXIDE FOR HIGH VOLTAGE, AND METHOD FOR PREPARING SAME
(FR) MATÉRIAU ACTIF D'ÉLECTRODE POSITIVE POUR BATTERIE RECHARGEABLE AU LITHIUM, CONTENANT DE L'OXYDE DE COBALT ET DE LITHIUM HAUTE TENSION, ET SON PROCÉDÉ DE PRÉPARATION
(KO) 고전압용 리튬 코발트 산화물을 포함하는 리튬 이차전지용 양극 활물질 및 이를 제조하는 방법
Abstract:
(EN) The present invention provides a positive electrode active material for a lithium secondary battery, the active material comprising a dopant and having a crystalline structure in which metal oxide layers (MO layers) comprising metals and oxygen and reversible lithium layers are repeatedly stacked, wherein in a lattice configured by oxygen atoms of the MO layers adjacent to each other, the dopant and/or lithium ions move from octahedral sites to tetrahedral sites at the time of charge, thereby forming a lithium trap and/or lithium dumbbell structure.
(FR) La présente invention concerne un matériau actif d'électrode positive pour une batterie rechargeable au lithium, le matériau actif comprenant un dopant et ayant une structure cristalline dans laquelle des couches d'oxyde métallique (couches MO) comprenant des métaux et de l'oxygène et des couches de lithium réversibles sont empilées de manière répétée. Dans un réseau configuré par des atomes d'oxygène des couches MO adjacentes les unes aux autres, les ions de dopant et/ou de lithium se déplacent de sites octaédriques à des sites tétraédriques au moment de la charge, formant ainsi une structure de piège à lithium et/ou d'haltère de lithium.
(KO) 본 발명은 도펀트를 포함하며, 금속과 산소를 포함하는 MO층 (metal oxide layer)과 가역적 리튬층 (lithium layer)이 반복적으로 적층되어 있는 결정 구조를 가지고 있고, 상기 도편트 및 /또는 리튬 이온이 상호 인접한 MO층들의 산소 원소들이 이루는 격자 내에서, 충전시 옥타헤드랄 (octahedral) 위치로부터 테트라헤드랄 (tetrahedral) 위치로 이동하여 리튬 트랩 (trap) 및/또는 리튬 덤벨 (dumbbell) 구조를 형성하는 리튬 이차전지용 양극 활물질을 제공한다.
