Abstract:
(EN) Disclosed is a secondary battery comprising: an electrode assembly in which a first electrode plate, a second electrode plate, and a separator are rolled up; and a support plate which is coupled to one end surface of the electrode assembly where the rolled first electrode plate, second electrode plate, and separator are exposed, so as to support the electrode assembly. A secondary battery according to an embodiment of the present invention comprises a support plate coupled to the lower end of an electrode assembly, whereby, when the secondary battery falls, movements of the electrode assembly can be prevented, and deformation of the electrode assembly due to an external impact can be suppressed.
(FR) L'invention concerne une batterie secondaire comprenant : un ensemble d'électrodes dans lequel sont enroulés une première plaque d'électrode, une deuxième plaque d'électrode et un séparateur ; et une plaque de support qui est couplée à une surface d'extrémité de l'ensemble d'électrodes où sont exposés la première plaque d'électrode, la deuxième plaque d'électrode et le séparateur enroulés, de façon à supporter l'ensemble d'électrodes. Une batterie secondaire selon un mode de réalisation de la présente invention comprend une plaque de support couplée à l'extrémité inférieure d'un ensemble d'électrodes qui permet, lorsque la batterie secondaire chute, d'empêcher les mouvements de l'ensemble d'électrodes et d'éliminer la déformation de l'ensemble d'électrodes due à un impact externe.
(KO) 전극 조립체의 제1 전극판, 제2 전극판 및 세퍼레이터의 권취가 노출되는 일 단면에 결합되며 전극 조립체를 지지하는 지지 플레이트를 포함하는 이차 전지가 개시된다. 본 발명의 실시예에 따른 이차 전지는 전극 조립체의 하단에 결합된 지지 플레이트로 인해, 이차 전지의 낙하 시 전극 조립체의 유동을 방지할 수 있고, 외부 충격으로 전극 조립체의 변형을 억제할 수 있다.
