Title (EN) LITHIUM SECONDARY BATTERY EXHIBITING EXCELLENT PERFORMANCE
(FR) BATTERIE RECHARGEABLE AU LITHIUM PRÉSENTANT UNE EXCELLENTE PERFORMANCE
(KO) 성능이 우수한 리튬 이차전지
Abstract: front page image
(EN)The present invention provides a lithium secondary battery comprising an electrode assembly and an electrolyte, wherein the electrode assembly includes a cathode having a cathode mixing layer formed on a cathode collector, an anode having an anode mixing layer formed on an anode collector, and a separator disposed between the cathode and the anode. The lithium secondary battery of the present invention is characterized in that the anode includes a lithium titanium oxide (LTO) as an anode active material, and the length of four sides of the cathode mixing layer is equal to or greater than the length of four sides of the anode mixing layer so that the area of the cathode mixing layer is equal to or greater than the area of the anode mixing layer.
(FR)La présente invention concerne une batterie rechargeable au lithium, comprenant un ensemble d'électrodes et un électrolyte, ledit ensemble d'électrodes comprenant une cathode présentant une couche de mélange cathodique formée sur un collecteur de cathode, une anode présentant une couche de mélange anodique formée sur un collecteur d'anode, et un séparateur disposé entre la cathode et l'anode. La batterie rechargeable au lithium selon l'invention est caractérisée en ce que l'anode comprend du titanate de lithium (LTO) en tant que matériau actif d'anode, et en ce que la longueur des quatre côtés de la couche de mélange cathodique est supérieure ou égale à la longueur des quatre côtés de la couche de mélange anodique, de telle façon que la superficie de la couche de mélange cathodique est supérieure ou égale à la superficie de la couche de mélange anodique.
(KO)본 발명은 양극 집전체 상에 양극 합제층이 형성되어 있는 양극, 음극 집전체 상에 음극 합제층이 형성되어 있는 음극, 및 상기 양극과 상기 음극 사이에 배치되는 분리막으로 구성된 전극조립체 및 전해액을 포함하는 리튬 이차전지로서, 상기 음극이 음극 활물질로서 리튬 티타늄 산화물(Lithium Titanium Oxide: LTO)을 포함하고 있고, 상기 양극 합제층의 네 면의 길이가 상기 음극 합제층의 네 면의 길이보다 같거나 길어서 상기 양극 합제층의 면적이 상기 음극 합제층의 면적보다 같거나 큰 것을 특징으로 하는 리튬 이차전지를 제공한다.
