Abstract
(EN)
A multilayer electrode (2) formed by stacking a plurality of positive plates (11) and a plurality of negative plates (16) alternately with separators (15) interposed therebetween. Each of the positive plates (11) and the negative plates (16) is sectioned into a rectangular region coated with an electrode material on the opposite sides and a region extending from one side of the rectangular region and not coated with the electrode material and is rectangular. Each separator (15) is formed like a bag, and the side corresponding to the region of the positive electrode (11) not coated with the electrode material is extended in order to contain the positive plate (11). A cut (12) is formed in a portion of the positive plate (11) at least partially covered with the separator, and the opposing regions of the separators (15) are fused thermally through the cut (12).
(FR)
Electrode multicouche (2) formée en empilant une pluralité de plaques positives (11) et une pluralité de plaques négatives (16) alternativement avec des séparateurs (15) interposés entre elles. Chacune des plaques positives (11) et des plaques négatives (16) est rectangulaire et sectionnée en une région rectangulaire enduite d'un matériau pour électrode sur les côtés opposés et en une région s'étendant d'un côté de la région rectangulaire et non enduite du matériau pour électrode. Chaque séparateur (15) a la forme d'un sac, et le côté correspondant à la région de l'électrode positive (11) non enduite du matériau pour électrode est étendu afin de maintenir la plaque positive (11). Une coupure (12) est effectuée dans une partie de la plaque positive (11) au moins partiellement couverte par le séparateur, et les régions opposées des séparateurs (15) sont fusionnées thermiquement via la coupure (12).

電極積層体2は、複数の正極板11と複数の負極板16とが、セパレータ15を介して互いに積層されている。正極板11および負極板16は、電極材料が両面に塗布された矩形状の領域と、この領域の1辺から延びた、電極材料が塗布されていない領域とに区画され、実質的に矩形状である。セパレータ15は、袋状に形成されており、正極板11の電極材料が塗布されていない領域側の辺を延出させて、正極板11を収容している。正極板11には、少なくとも一部がセパレータに覆われる部位に切除部12が形成されており、セパレータ15は、切除部12を通して対向する領域同士が熱融着されている。
