Abstract
(EN)
Disclosed is a battery module (10) and a battery pack (30). The battery module (10) comprises two or more secondary batteries (11), the two or more secondary batteries (11) being arranged side by side in a first direction (X), and each of the secondary batteries (11) comprising a shell (12), an electrode component (13) and a sealing portion, wherein the shell (12) comprises an accommodating hole (12a) with an opening; the accommodating hole (12a) extends in a second direction (Y); the first direction (X) intersects the second direction (Y); the sealing portion is hermetically connected to the shell (12) to cover and close the opening; the electrode component (13) is arranged in the accommodating hole (12a) and comprises two or more electrode units (14); each of the electrode units (14) comprises a first electrode plate (141), a second electrode plate (142) and a diaphragm (143); and the two or more electrode units (14) are arranged in a stacked manner in the second direction (Y). The battery module (10) itself has small expansion capacity in the direction in which the secondary batteries (11) are arranged, such that the safety during use can be effectively improved.

La présente invention concerne un module de batterie (10) et un bloc-batterie (30). Le module de batterie (10) comprend deux ou plusieurs batteries secondaires (11), les deux ou plusieurs batteries secondaires (11) étant agencées côte à côte dans une première direction (X), et chacune des batteries secondaires (11) comprenant une coque (12), un composant d'électrode (13) et une partie d'étanchéité, la coque (12) comprenant un trou de réception (12a) ayant une ouverture ; le trou de réception (12a) s'étend dans une seconde direction (Y) ; la première direction (X) croise la seconde direction (Y) ; la partie d'étanchéité est hermétiquement reliée à la coque (12) pour recouvrir et fermer l'ouverture ; le composant d'électrode (13) est disposé dans le trou de réception (12a) et comprend deux ou plusieurs unités d'électrode (14) ; chacune des unités d'électrode (14) comprend une première plaque d'électrode (141), une seconde plaque d'électrode (142) et un diaphragme (143) ; et les deux ou plusieurs unités d'électrode (14) sont agencées de manière empilée dans la seconde direction (Y). Le module de batterie (10) lui-même présente une faible capacité d'expansion dans la direction dans laquelle les batteries secondaires (11) sont agencées, de telle sorte que la sécurité pendant l'utilisation peut être efficacement améliorée.
