Title (EN) CATHODE FOR LITHIUM SECONDARY BATTERY AND LITHIUM SECONDARY BATTERY CONTAINING SAME
(FR) CATHODE POUR BATTERIE SECONDAIRE AU LITHIUM, ET BATTERIE SECONDAIRE AU LITHIUM QUI CONTIENT CETTE DERNIÈRE
(KO) 리튬 이차전지용 음극 및 이를 포함하는 리튬이온 이차 전지
Abstract: front page image
(EN)The present invention relates to a cathode for a secondary battery including a cathode collector, a cathode active material coated on the cathode collector, and a protuberance (cathode tab) formed by projecting a part of the cathode collector to one side and not coated with the cathode active material, wherein the protuberance adjoins a metal member having a higher reactivity or reducibility to a metal oxide than the cathode collector, and to a secondary battery including the same.
(FR)La présente invention se rapporte à une cathode pour une batterie secondaire, ladite cathode comprenant un collecteur de cathode, un matériau actif de cathode recouvert sur le collecteur de cathode, et une saillie (une languette de cathode) formée par projection d'une partie du collecteur de cathode vers un côté et qui n'est pas recouverte avec le matériau actif de cathode, la saillie étant attenante à un élément métallique qui présente une réactivité, ou une réductibilité, plus élevée à un oxyde métallique que le collecteur de cathode. La présente invention se rapporte également à une batterie secondaire qui comprend cette cathode.
(KO)본 발명은 음극집전체, 상기 음극집전체 상에 코팅된 음극활물질, 및 상기 음극집전체 일부분이 일측으로 돌출된 상태로 음극활물질이 코팅되지 않은 무지부(음극탭)를 포함하는 음극에 있어서, 상기 무지부에 접합되어 있는, 상기 음극집전체보다 금속 산화물에 대한 반응성 또는 환원성이 높은 금속 부재를 포함하는 이차전지용 음극과, 이를 포함하는 이차전지에 관한 것이다.
