Abstract[English]
A sealing assembly (2), a cover plate assembly, a cylinder, a battery cell casing member, and a battery cell. The sealing assembly (2) comprises a protection mechanism (6) and a dissolving mechanism (7). The protection mechanism (6) is used for isolating the dissolving mechanism from an electrolyte in the inner cavity of the battery cell, and the dissolving mechanism (7) is used for dissolving under the action of an external electrolyte, and enabling the protection mechanism (6) to fall off from the battery cell casing; and the dissolving mechanism (7) is made of a material soluble in the electrolyte, and the protection mechanism (6) is made of a material insoluble in the electrolyte. The cover plate assembly (2), the cylinder, the battery cell casing member, and the battery cell are all provided with the sealing assembly (2). The sealing assembly (2) can be reliably mounted to the battery cell casing, has good sealing performance, and can be smoothly opened by using the electrolyte.[French]
L'invention concerne un ensemble d'étanchéité (2), un ensemble plaque de couverture, un cylindre, un élément de boîtier d'élément de batterie et un élément de batterie. L'ensemble d'étanchéité (2) comprend un mécanisme de protection (6) et un mécanisme de dissolution (7). Le mécanisme de protection (6) est utilisé pour isoler le mécanisme de dissolution vis-à-vis d'un électrolyte dans la cavité interne de l'élément de batterie, et le mécanisme de dissolution (7) est utilisé pour se dissoudre sous l'action d'un électrolyte externe et permettre au mécanisme de protection (6) de se détacher du boîtier d'élément de batterie ; et le mécanisme de dissolution (7) est constitué d'un matériau soluble dans l'électrolyte et le mécanisme de protection (6) est constitué d'un matériau insoluble dans l'électrolyte. L'ensemble plaque de couverture (2), le cylindre, l'élément de boîtier d'élément de batterie et l'élément de batterie sont tous pourvus de l'ensemble d'étanchéité (2). L'ensemble d'étanchéité (2) peut être monté de manière fiable sur le boîtier d'élément de batterie, présente de bonnes performances d'étanchéité et peut être ouvert sans à-coups à l'aide de l'électrolyte.[Chinese]
一种密封组件（2）、盖板组件、筒体、单体电池壳体构件及单体电池，密封组件（2），包括保护机构（6）和溶解机构（7）；保护机构（6）用于将溶解机构与单体电池内腔电解液隔离；溶解机构（7）用于在外部电解液的作用下，溶解，并使保护机构（6）从单体电池壳体脱落；溶解机构（7）的材质为电解液可溶材质，保护机构（6）的材质为电解液不可溶材质；盖板组件（2）、筒体、单体电池壳体构件及单体电池均具有上述密封组件（2）。该密封组件（2）与单体电池壳体可实现可靠安装，且具有较好的密封性，同时利用电解液可以顺利打开。
