Abstract
(EN) A battery (10) and a related apparatus therefor, a preparation method, and a preparation device. The battery (10) comprises a plurality of battery cells (20), at least one of the plurality of battery cells (20) comprising a pressure relief mechanism (213) used for actuating when the internal pressure of the at least one battery cell (20) reaches a threshold so as to release the internal pressure; and a convergence component (12) used for electrically connecting the plurality of battery cells (20), wherein the pressure relief mechanism (213) and the convergence component (12) are respectively arranged on different sides of the at least one battery cell (20), so that the emissions from the at least one battery cell (20) are discharged along the direction distant from the convergence component (12) when the pressure relief mechanism (213) is actuated. By means of the arrangement mode of the pressure relief mechanism (213) and the convergence component (12), the safety performance of the battery (10) is significantly improved.
(FR) L'invention concerne une batterie (10) et un appareil associé correspondant, un procédé de préparation et un dispositif de préparation. La batterie (10) comprend une pluralité de cellules de batterie (20), dont au moins une parmi la pluralité de cellules de batterie (20) comprend un mécanisme de décompression (213) utilisé pour être actionné lorsque la pression interne dudit au moins une cellule de batterie (20) atteint un seuil pour relâcher la pression interne; et un composant de convergence (12) utilisé pour la connexion électrique de la pluralité de cellules de batterie (20), le mécanisme de décompression (213) et le composant de convergence (12) étant respectivement disposés sur des côtés différents de ladite au moins une cellule de batterie (20), de sorte que les émissions provenant du ou des élément(s) de batterie (20) sont déchargées selon la direction en éloignement du composant de convergence (12) lorsque le mécanisme de décompression (213) est actionné. Grâce au mode d'agencement du mécanisme de décompression (213) et du composant de convergence (12), les performances de sécurité de la batterie (10) sont considérablement améliorées.
(ZH) 一种电池(10)及其相关装置、制备方法和制备设备。该电池(10)包括多个电池单体(20),所述多个电池单体(20)中的至少一个电池单体(20)包括泄压机构(213),所述泄压机构(213)用于在所述至少一个电池单体(20)的内部压力达到阈值时致动以泄放所述内部压力;以及汇流部件(12),用于电连接所述多个电池单体(20);其中,所述泄压机构(213)与所述汇流部件(12)分别被布置在所述至少一个电池单体(20)的不同侧,以使得在所述泄压机构(213)致动时来自所述至少一个电池单体(20)的排放物沿远离所述汇流部件(12)的方向排放。通过泄压机构(213)和汇流部件(12)的这种布置方式,使得电池(10)的安全性能得到显著提高。
