(KO) 음극 및 상기 음극을 포함하는 이차 전지
Abstract:
(EN) The present invention relates to a negative electrode and a secondary battery including the same, comprising: a current collector; a first active material layer, which comprises a first active material particle and is disposed on the current collector; and a first pattern and a second pattern, which are alternately arranged on the first active material layer while being spaced from each other, wherein the first pattern comprises a first pattern active material particle, the second pattern comprises a second pattern active material particle, the first pattern is thicker than the second pattern, and the second pattern has a volume expansion rate larger than that of the first pattern.
(FR) La présente invention concerne une électrode négative et une batterie secondaire comprenant celle-ci, comprenant : un collecteur de courant; une première couche de matériau actif, qui comprend une première particule de matériau actif et qui est disposée sur le collecteur de courant; et un premier motif et un second motif, qui sont disposés en alternance sur la première couche de matériau actif tout en étant espacés l'un de l'autre, le premier motif comprenant une première particule de matériau actif de motif, le second motif comprenant une seconde particule de matériau actif de motif, le premier motif étant plus épais que le second motif, et le second motif ayant un taux de dilatation de volume supérieur à celui du premier motif.
(KO) 집전체; 제1 활물질 입자를 포함하며 상기 집전체 상에 배치된 제1 활물질층; 및 상기 제1 활물질층 상에서 서로 이격되어 교대로 배치된 제1 패턴 및 제2 패턴을 포함하되, 상기 제1 패턴은 제1 패턴 활물질 입자를 포함하고, 상기 제2 패턴은 제2 패턴 활물질 입자를 포함하며, 상기 제1 패턴의 두께는 상기 제2 패턴의 두께보다 크고, 상기 제2 패턴의 부피 팽창률은 상기 제1 패턴의 부피 팽창률보다 큰 음극 및 이를 포함하는 이차 전지에 관한 것이다.
