Title (EN) SECONDARY BATTERY HAVING IMPROVED LIFESPAN BY USING ELECTROLYTE STORAGE MEMBER
(FR) PILE RECHARGEABLE À DURÉE DE VIE AMÉLIORÉE À L'AIDE D'UN ÉLÉMENT DE STOCKAGE D'ÉLECTROLYTE
(KO) 전해액 저장부재에 의해 수명 특성이 개선된 이차전지
Abstract:
(EN) A battery cell comprises: an electrode assembly comprising a cathode, an anode, and a separation membrane interposed between the cathode and the anode; and a battery case of a laminate sheet including a receiving part in which the electrode assembly is embedded, wherein the receiving part has a structure in which the laminate sheet is indented at a depth corresponding to the height of the electrode assembly, and at least one electrolyte storage part capable of additionally having an electrolyte embedded therein is formed, in a structure of communicating with the receiving part, on at least one side portion among side portions of the receiving part facing side surfaces of the electrode assembly.
(FR) La présente invention concerne une pile qui comprend : un ensemble électrode comportant une cathode, une anode et une membrane de séparation interposée entre ces dernières ; un boîtier de pile en une feuille stratifiée comprenant une partie réception dans laquelle l'ensemble électrode est incorporé, la partie réception ayant une structure selon laquelle la feuille stratifiée est dentelée à une profondeur correspondant à la hauteur de l'ensemble électrode, et au moins une partie stockage d'électrolyte dans laquelle un électrolyte peut être en outre incorporé étant formée, dans une structure de communication avec la partie réception, sur au moins une partie latérale parmi des parties latérales de la partie réception en regard des surfaces latérales de l'ensemble électrode.
(KO) 양극, 음극, 및 상기 양극 및 음극 사이에 개재되는 분리막을 포함하는 전극조립체, 및 상기 전극조립체가 내장되는 수납부를 구비하고 있는 라미네이트 시트의 전지케이스를 포함하고 있고; 상기 수납부는 전극조립체의 높이에 대응하는 깊이로 라미네이트 시트가 만입되어 있는 구조로 이루어져 있으며; 상기 전극조립체의 측면들이 대면하는 수납부의 측면부들 중에서 적어도 하나의 측면부에는, 전해액을 추가 내장할 수 있는 적어도 하나 이상의 전해액 저장부가 수납부와 연통된 구조로 형성되어 있는 것을 특징으로 하는 전지셀에 관한 것이다.
