Abstract:
(EN) Provided are an electrode assembly capable of realizing a high output with low resistance, a secondary battery comprising the same, and a method for manufacturing the same. An electrode assembly according to the present invention comprises: a cathode plate having a cathode current collector, a cathode active material, and a cathode tab; an anode plate having an anode current collector, an anode active material, and an anode tab; and a separator interposed between the cathode plate and the anode plate, wherein at least one of the cathode plate and the anode plate implements the tab in both directions with respect to the current collectors so that the cathode tab and the anode tab form an angle of 90 degrees. According to the present invention, since a lead/current collector is formed in both directions with respect to at least one of the electrodes, current flows in both directions on the basis of each of the cathode and the anode, thereby reducing cell resistance.
(FR) L'invention concerne un ensemble à électrodes permettant de réaliser une sortie élevée avec une faible résistance, une batterie rechargeable la comprenant et son procédé de fabrication. L'ensemble à électrodes selon la présente invention comprend : une plaque de cathode comportant un collecteur de courant cathodique, un matériau actif de cathode et une patte de cathode; une plaque d'anode comportant un collecteur de courant anodique, un matériau actif d'anode et une patte d'anode; et un séparateur intercalé entre la plaque de cathode et la plaque d'anode, la plaque de cathode et/ou la plaque d'anode mettant en œuvre la patte dans les deux sens par rapport aux collecteurs de courant de manière que la patte de cathode et la patte d'anode forment un angle de 90 degrés. Selon la présente invention, étant donné qu'un conducteur/collecteur de courant est formé dans les deux sens par rapport à au moins une des électrodes, le courant circule dans les deux sens sur la base de la cathode et de l'anode, ce qui permet de réduire la résistance de la pile.
(KO) 저항이 낮으면서 고출력을 구현할 수 있는 전극 조립체, 이를 포함하는 이차 전지 및 그 제조방법을 제공한다. 본 발명에 따른 전극 조립체는 양극 집전체, 양극 활물질 및 양극 탭을 구비하는 양극판; 음극 집전체, 음극 활물질 및 음극 탭을 구비하는 음극판; 및 상기 양극판과 상기 음극판 사이에 개재된 세퍼레이터를 포함하고, 상기 양극판과 음극판 중 적어도 어느 하나는 상기 집전체에 대해 상기 탭을 양방향으로 구현하여, 상기 양극 탭과 상기 음극 탭이 90도 각도를 이루고 있는 것이다. 본 발명에 따르면, 리드/집전체가 각 전극 중 적어도 어느 하나에 대해서는 양방향으로 구성되어 있어 양/음극 각각을 기준으로 전류가 양방향으로 흐르게 하므로 셀 저항이 줄어든다.
