Title (EN) ELECTRODE ASSEMBLY AND SECONDARY BATTERY INCLUDING SAME
(FR) ENSEMBLE D’ÉLECTRODES ET BATTERIE RECHARGEABLE QUI EN EST DOTÉE
(KO) 전극 조립체 및 이를 포함하는 이차전지
Abstract:
(EN) An electrode assembly according to an embodiment of the present invention comprises: a first electrode plate including a first electrode tab on one end of one side surface thereof; a second electrode plate including a second electrode tab formed in a direction that is the same as the lengthwise direction of the first electrode tab but at a position in which the second electrode tab does not overlap the first electrode tab, and a projecting portion formed at a position that overlaps the first electrode tab; and a separation membrane for insulating the first electrode plate and the second electrode plate. Accordingly, an electrode assembly and a secondary battery including same according to an embodiment of the present invention can improve the stability of a secondary battery by preventing lithium ion accumulation by means of a separation membrane.
(FR) Un ensemble d’électrodes selon un mode de réalisation de la présente invention comprend : une première plaque d’électrode comprenant une première languette d’électrode à une extrémité d’une de ses surfaces latérales ; une deuxième plaque d’électrode comprenant une deuxième languette d’électrode formée dans une direction qui est la même que la direction longitudinale de la première languette d’électrode, mais à une position à laquelle la deuxième languette d’électrode ne chevauche pas la première languette d’électrode, et une partie en saillie formée à une position qui chevauche la première languette d’électrode ; et une membrane de séparation servant à isoler la première plaque d’électrode et la deuxième plaque d’électrode. Par conséquent, un ensemble d’électrodes et une batterie rechargeable qui en est dotée selon un mode de réalisation de la présente invention permettent d’améliorer la stabilité de la batterie rechargeable en empêchant l’accumulation d’ions lithium au moyen d’une membrane de séparation.
(KO) 본 발명의 일 실시예에 따른 전극 조립체는 일측면의 끝단에 제 1 전극탭을 갖는 제 1 전극판, 상기 제 1 전극탭의 길이 방향과 동일한 방향으로 형성되되, 상기 제 1 전극탭과 오버랩되지 않는 위치에 형성되는 제 2 전극탭과 상기 제 1 전극탭과 오버랩되는 위치에 형성되는 돌출부를 갖는 제 2 전극판, 및 상기 제 1 전극판과 제 2 전극판을 절연시키는 분리막을 포함한다. 따라서, 본 발명의 일 실시예에 따른 전극 조립체 및 이를 포함하는 이차전지는 분리막으로의 리튬이온 축적을 방지하여 이차전지의 안정성을 향상시킬 수 있다.
