(ZH) 一种电池外壳及电池
Abstract
(EN) The present application provides a battery housing and a battery. The battery housing comprises a first cover body, a second cover body, a sealing member, and a housing body; the second cover body is welded to the housing body; the first cover body is adhered to the second cover body by means of the sealing member, so as to seal the housing body; and the adhesion between the first cover body and the second cover body is less than a first pressure, and the first pressure is a pressure borne by the battery housing when the battery housing explodes. When a battery explodes, an adhesive layer between the first cover body and the second cover body can be broken through, so as to release gas generated inside the battery housing, avoiding further increase of internal pressure of the battery housing which causes explosion.
(FR) L'invention concerne un bac de batterie et une batterie. Le bac de batterie comprend un premier corps de couvercle, un second corps de couvercle, un élément d'étanchéité et un corps de bac ; le second corps de couvercle est soudé au corps de bac ; le premier corps de couvercle est collé au second corps de couvercle au moyen de l'élément d'étanchéité, de façon à sceller le corps de bac ; et l'adhérence entre le premier corps de couvercle et le second corps de couvercle est inférieure à une première pression, et la première pression est une pression portée par le bac de batterie lorsque le bac de batterie explose. Lorsqu'une batterie explose, une couche adhésive entre le premier corps de couvercle et le second corps de couvercle peut être rompue, de manière à libérer le gaz généré à l'intérieur du bac de batterie, ce qui permet d'éviter une augmentation supplémentaire de la pression interne du bac de batterie qui provoque l'explosion.
(ZH) 本申请提供一种电池外壳及电池,其中,所述电池外壳包括:第一盖体、第二盖体、密封件和壳体,所述第二盖体与所述壳体焊接,所述第一盖体通过所述密封件与所述第二盖体粘接,以密封所述壳体;其中,所述第一盖体和所述第二盖体之间的粘接力小于第一压力,所述第一压力为所述电池外壳爆炸时所承受的压力。在电池发生爆炸时,可冲破第一盖体和第二盖体之间的粘接层,以释放所述电池外壳内部产生的气体,避免所述电池外壳内压继续升高而发生爆炸。
