Abstract

La présente invention aborde le problème de la fourniture d'un bloc-batterie qui peut empêcher le court-circuitage de cellules de batterie supérieures et inférieures provoqué par une fuite d'électrolyte lorsqu'une soupape de sécurité disposée dans la cellule de batterie est ouverte. La solution est un bloc-batterie comprenant une pluralité de cellules de batterie rectangulaires plates (1) et une pluralité de supports de cellules (22). La cellule de batterie (1) comporte une soupape de sécurité (1V) sur une de ses surfaces d'extrémité (1a) le long du sens de l'épaisseur (Dt). Le support de cellule (22) comporte une partie d'extension (221) s'étendant dans le sens de l'épaisseur (Dt) vers la soupape de sécurité (1V) le long de la surface d'extrémité (1a) de la cellule de batterie (1) et s'étendant dans une direction perpendiculaire au sens de l'épaisseur (Dt) le long de la surface d'extrémité (1a). Une partie d'espace évidée (222) est formée entre la surface d'extrémité (1a) de la cellule de batterie (1) et une surface d'extrémité (221a) de la partie d'extension (221) opposée à la surface d'extrémité (1a).
