Abstract
(EN)
The present invention relates to a lithium secondary battery case composed of laminate sheet including an outer layer/barrier layer/inner layer structure, the case comprising: a first area which is an area in which gas discharge is easier or expansion is relatively better; and a second area which is the remaining area that excludes the first area, wherein the laminate sheet that forms the first area does not include a barrier layer or includes a barrier layer having a slit.
(FR)
La présente invention concerne un boîtier de batterie secondaire au lithium composé d'une feuille stratifiée comprenant une structure couche externe/couche barrière/couche interne, le boîtier comprenant : une première zone qui est une zone dans laquelle la décharge de gaz est plus facile ou l'expansion est relativement meilleure ; et une deuxième zone qui est la zone restante qui exclut la première zone, la feuille stratifiée qui forme la première zone ne comprenant pas de couche barrière ou comprenant une couche barrière ayant une fente.
