Title (EN) CURVED BATTERY CELL HAVING LOW STRUCTURAL DEFORMATION AND METHOD FOR MANUFACTURING SAME
(FR) PILE COURBE À FAIBLE DÉFORMATION STRUCTURALE ET SON PROCÉDÉ DE FABRICATION
(KO) 구조 변형이 적은 곡면 전지셀 및 이를 제조하는 방법
Abstract:
(EN) The present invention provides a battery cell having a structure in which an electrode assembly comprising an anode, a cathode, and a separator, together with an electrolyte solution, is sealed in a cell case by thermally fusing the outer circumferential edges of the cell case in the state where the electrode assembly and the electrolyte solution are received in the cell case, wherein the electrode assembly and the cell case have a structure in which the ends of the electrode assembly and the cell case, opposite to each other, are bent together in the same direction such that a curved surface is formed on the outer surface of the battery cell, and at least one of the thermally fused outer circumferential edges of the cell case is bent so as to come in close contact with the surface that is curved while forming the inner surface.
(FR) La présente invention concerne une pile possédant une structure dans laquelle un ensemble d'électrodes, comportant une anode, une cathode et un séparateur, est enfermé hermétiquement avec une solution électrolytique dans un boîtier de pile par thermocollage des bords circonférentiels extérieurs du boîtier de pile dans l'état où l'ensemble d'électrodes et la solution électrolytique sont reçus dans le boîtier de pile, l'ensemble d'électrodes et le boîtier de pile possédant une structure dans laquelle les extrémités de l'ensemble d'électrodes et du boîtier de pile, en regard les unes des autres, sont courbées ensemble dans le même sens de manière à former une surface courbe sur la surface extérieure de la pile, et au moins l'un des bords circonférentiels extérieurs thermocollés du boîtier de pile est courbé de manière à entrer en contact étroit avec la surface qui est courbée tout en formant la surface intérieure.
(KO) 본 발명은 양극, 음극, 및 분리막을 포함하는 전극조립체가 전해액과 함께 셀 케이스 내부에 수납된 상태로 셀 케이스의 외주변들이 열융착에 의해 밀봉된 구조의 전지셀로서, 상기 전극조립체와 셀 케이스는, 전지셀의 외면에 곡면이 형성되도록, 서로 대향하는 위치의 양측 단부들이 동일한 방향으로 함께 휘어 있는 구조로 이루어져 있고, 상기 셀 케이스의 열융착된 외주변들 중에서 적어도 하나의 외주변은 안쪽 면을 이루면서 휘어진 면에 밀착되도록 절곡되어 있는 것을 특징으로 하는 전지셀을 제공한다.
