Abstract
(EN) Disclosed are a battery and a related apparatus thereof, and a preparation method and a preparation device. The battery comprises: a battery cell, wherein the battery cell comprises a pressure relief mechanism, and the pressure relief mechanism is configured to be capable of being actuated when the internal pressure or temperature of the battery cell reaches a threshold so as to release the internal pressure; an attachment member adapted to be attached to the battery cell by means of an adhesive; and an isolation member, wherein the isolation member is configured to be capable of preventing the adhesive from being applied between the attachment member and the pressure relief mechanism. An isolation member is provided, such that an adhesive can be effectively prevented from being applied between an attachment member and a pressure relief mechanism during battery production. In addition, the adhesive application efficiency and accuracy can also be improved, so as to improve the battery production efficiency.
(FR) Sont divulgués une batterie et un appareil associé à celle-ci, ainsi qu'un procédé de préparation et un dispositif de préparation. La batterie comprend : une cellule de batterie, la cellule de batterie comprenant un mécanisme de décompression, le mécanisme de décompression étant conçu pour être actionné lorsque la pression ou la température interne de la cellule de batterie atteint un seuil de manière à libérer la pression interne ; un élément de fixation conçu pour être fixé à la cellule de batterie au moyen d'un adhésif ; et un élément isolant, l'élément isolant étant conçu pour empêcher l'adhésif d'être appliqué entre l'élément de fixation et le mécanisme de décompression. Un élément isolant est prévu, de telle sorte qu'il est possible d'empêcher efficacement un adhésif d'être appliqué entre un élément de fixation et un mécanisme de décompression pendant la production de la batterie. De plus, l'efficacité et la précision de l'application de l'adhésif peuvent également être améliorées, de façon à améliorer l'efficacité de production de la batterie.
(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。该电池包括电池单体,所述电池单体包括泄压机构,所述泄压机构被构造成能够在所述电池单体的内部压力或温度达到阈值时致动以泄放所述内部压力;以及附接部件,其适于通过粘接剂附接至所述电池单体;以及隔离部件,所述隔离部件被构造成能够防止所述粘接剂施加在所述附接部件和所述泄压机构之间。通过设置隔离部件,能够在电池生产过程中以有效的方式防止粘接剂施加在所述附接部件和所述泄压机构之间。同时,还能够提高粘接剂的施加效率和准确性,从而提高电池的生产效率。
