Abstract[English]
The present application discloses a novel housing, comprising a side wall (131) and a housing bottom cover (13). The central region of the housing bottom cover (13) is an explosion-proof region (1321). The area of the explosion-proof region (1321) is not greater than 1/2 of the area of the housing bottom cover (13), and the thickness of the explosion-proof region (1321) is not greater than the thickness of the housing bottom cover (13). An explosion-proof notch (13211) is provided in the explosion-proof region (1321). After the explosion-proof region is provided in the central region of the bottom of the housing of the present application, when thermal runaway occurs in a battery, the explosion-proof region bursts by means of the explosion-proof notch, and blockage is not prone to occur, thereby improving the safety of the battery on the whole, and also reducing the processing and manufacturing costs of the housing.[French]
La présente invention concerne un nouveau boîtier, comprenant une paroi latérale (131) et un couvercle inférieur de boîtier (13). La région centrale du couvercle inférieur de boîtier (13) est une région antidéflagrante (1321). La zone de la région antidéflagrante (1321) n'est pas supérieure à 1/2 de la zone du couvercle inférieur de boîtier (13), et l'épaisseur de la région antidéflagrante (1321) n'est pas supérieure à l'épaisseur du couvercle inférieur de boîtier (13). Une encoche antidéflagrante (13211) est disposée dans la région antidéflagrante (1321). Après que la région antidéflagrante est disposée dans la région centrale du fond du boîtier de la présente demande, lorsqu'un emballement thermique se produit dans une batterie, la région antidéflagrante éclate au moyen de l'encoche antidéflagrante, et un blocage n'est pas susceptible de se produire, ce qui permet d'améliorer la sécurité de la batterie sur l'ensemble, et de réduire également les coûts de traitement et de fabrication du boîtier.[Chinese]
本申请公开了一种新型壳体,包括侧壁(131)和壳体底盖(13),壳体底盖(13)中心区域为防爆区(1321),防爆区(1321)面积不大于1/2壳体底盖(13)面积,防爆区(1321)厚度不大于壳体底盖(13)厚度,防爆区(1321)内设置防爆刻痕(13211)。在对本申请的壳体底部中心区域设置防爆区后,电池在发生热失控时,防爆区通过防爆刻痕爆破,且不易发生堵塞,从而整体上提高了电池的安全性,同时也降低了壳体的加工制造成本。
