Abstract
(EN)
The purpose of the present invention is to provide a power storage module that can continuously discharge a large current and for which welding strength is ensured. Provided is a power storage module comprising: at least two power storage cell bodies; a plate-like aluminum positive electrode terminal that protrudes without a step from inside of one of the power storage cell bodies in a direction orthogonal to a lamination direction and that has a thickness in the lamination direction of greater than 0.4mm and less than or equal to 1mm; a highly-rigid negative electrode terminal that has an overlap with the aluminum positive electrode terminal in a lamination direction view and that protrudes without a step from inside of overlapping power storage cell bodies; and an ultrasonic welding part formed by welding the aluminum positive electrode terminal and highly-rigid negative electrode terminal together in a region overlapping in the lamination direction view with at least one horn mark from ultrasonic welding provided on the surface of the aluminum positive electrode terminal. Overall, the width of the horn mark in a width direction intersecting, above the surface of the aluminum positive electrode terminal, a protrusion direction in which the aluminum positive electrode terminal protrudes is greater than a length of the horn mark in the protrusion direction.

L’objectif de la présente invention est de fournir un module de stockage d’électricité qui peut décharger en continu un courant élevé et pour lequel la résistance de soudure est assurée. L'invention concerne un module de stockage d'électricité comprenant : au moins deux corps de cellule de stockage d'électricité ; une borne d'électrode positive en aluminium de type plaque qui fait saillie sans gradin depuis l'intérieur de l'un des corps de cellule de stockage d'électricité dans une direction orthogonale à une direction de stratification et qui a une épaisseur dans la direction de stratification supérieure à 0,4 mm et inférieure ou égale à 1 mm ; une borne d'électrode négative hautement rigide qui comporte un chevauchement avec la borne d'électrode positive en aluminium dans une vue dans la direction de stratification et qui fait saillie sans gradin depuis l'intérieur des corps de cellule de stockage d'électricité se chevauchant ; et une partie de soudure ultrasonore formée par soudage de la borne d'électrode positive en aluminium et de la borne d'électrode négative hautement rigide conjointement dans une région de chevauchement dans la vue dans la direction de stratification avec au moins une marque de corne d'un soudage par ultrasons disposé sur la surface de la borne d'électrode positive en aluminium. Globalement, la largeur de la marque de corne dans une direction de la largeur coupant, au-dessus de la surface de la borne d'électrode positive en aluminium, une direction de saillie dans laquelle la borne d'électrode positive en aluminium fait saillie est supérieure à une longueur de la marque de corne dans la direction de saillie.
