Abstract
(EN) Disclosed in the present application are a battery and a related apparatus thereof and preparation method and preparation device therefor. The battery comprises a battery cell, a thermal management component, an avoidance cavity and a collecting cavity. The battery cell comprises a pressure relief mechanism; the thermal management component is used for accommodating fluid so as to adjust the temperature of the battery cell; the avoidance cavity is configured to provide a space allowing actuation of the pressure relief mechanism; and the collecting cavity is used for collecting emissions from the battery cell when the pressure relief mechanism is actuated. The thermal management component is configured to enable, when the pressure relief mechanism is actuated, the emissions of the battery cell to pass through the thermal management component and enter the collecting cavity via the avoidance cavity. According to the present application, as the avoidance cavity is provided, the pressure relief mechanism does not need to be arranged at the side of an electrode terminal of the battery cell; due to the provision of the collecting cavity, the emissions discharged by the pressure relief mechanism can be collected and will not spurt or flow to the outside and pollute other components or the environment.
(FR) La présente invention concerne une batterie et un appareil associé de celle-ci et son procédé de préparation et son dispositif de préparation. La batterie comprend une cellule de batterie, un composant de gestion thermique, une cavité d'évitement et une cavité de collecte. La cellule de batterie comprend un mécanisme de décompression ; le composant de gestion thermique est utilisé pour recevoir un fluide de façon à ajuster la température de la cellule de batterie ; la cavité d'évitement est configurée pour fournir un espace permettant l'actionnement du mécanisme de décompression ; et la cavité de collecte est utilisée pour collecter des émissions provenant de la cellule de batterie lorsque le mécanisme de décompression est actionné. Le composant de gestion thermique est configuré pour permettre, lorsque le mécanisme de décompression est actionné, aux émissions de la cellule de batterie de traverser le composant de gestion thermique et d'entrer dans la cavité de collecte par l'intermédiaire de la cavité d'évitement. Selon la présente invention, en tant que cavité d'évitement, le mécanisme de décompression n'a pas besoin d'être agencé sur le côté d'une borne d'électrode de la cellule de batterie ; du fait de la fourniture de la cavité de collecte, les émissions évacuées par le mécanisme de décompression peuvent être collectées et ne jaillissent ou ne s'écoulent pas vers l'extérieur ni ne polluent d'autres composants ou l'environnement.
(ZH) 本申请公开了一种电池及其相关装置、制备方法和制备设备。电池包括电池单体、热管理部件、避让腔和收集腔。电池单体包括泄压机构;热管理部件用于容纳流体以给电池单体调节温度;避让腔被构造为提供允许泄压机构致动的空间;收集腔用于在泄压机构致动时收集来自电池单体的排放物。其中,热管理部件被构造为使得在泄压机构致动时电池单体的排放物能够穿过热管理部件,从而经由避让腔进入收集腔。根据本申请,由于设置有避让腔,泄压机构可以不必设置在电池单体的电极端子一侧;收集腔的设置能够使得泄压机构所泄放出的排泄物能够被收集起来而不会喷射或流动至外界从而对其他部件或外界环境造成污染。
