Disclosed herein is a separation-type connecting member, which electrically connects electrode terminals of unit cells. The connecting member comprises two or more separated connecting bodies, which are connected to the corresponding electrode terminals during the assembly of a secondary battery module, and which are electrically connected with each other by additional conductive members to complete the battery module. The present invention also provides a method of improving the performance of a battery module that is capable of connecting unit cells in parallel with each other to level the voltage of the unit cells while the battery module is manufactured using the connecting member, specifically, before the unit cells are connected in series with each other, or while the battery module is used, thereby minimizing the voltage difference between the unit cells.
L~invention concerne un élément de connexion de type à séparation, qui connecte électriquement des bornes d~électrode de cellules unitaires. L~élément de connexion comprend deux corps de connexion séparés ou plus, qui sont connectés aux bornes d~électrode correspondantes pendant l~assemblage d~un module de batterie secondaire, et qui sont connectés électriquement les uns aux autres par des éléments conducteurs additionnels pour compléter le module de batterie. La présente invention concerne également un procédé d~amélioration des performances d~un module de batterie qui est susceptible de connecter des cellules unitaires en parallèle les unes aux autres pour niveler la tension des cellules unitaires pendant que le module de batterie est fabriqué en utilisant l~élément de connexion, spécifiquement, avant que les cellules unitaires ne soient connectées en série les unes aux autres, ou pendant que le module de batterie est utilisé, minimisant de ce fait la différence de tension entre les cellules unitaires.
