Summary:This unit cell is provided with: a bonded member in which a first metal and a second metal are bonded to a current path for charge/discharge current and an interface between the first metal and the second metal is formed; and a sacrificial anti-corrosion layer which is arranged on the bonded member so as to be in contact with the first metal and/or the second metal. The first metal is pure aluminum or an aluminum alloy. The second metal is pure copper or a copper alloy. The sacrificial anti-corrosion layer is formed of a material that has a larger ionization tendency than the first metal. Cette invention concerne un élément unitaire, comprenant : un élément assemblé dans lequel un premier métal et un second métal sont reliés à un trajet conducteur pour le courant de charge/décharge, une interface étant formée entre le premier métal et le second métal ; et une couche anticorrosive sacrificielle disposée sur l'élément assemblé de façon à être en contact avec le premier métal et/ou le second métal. Le premier métal est de l'aluminium pur ou un alliage d'aluminium. Le second métal est du cuivre pur ou un alliage de cuivre. La couche anticorrosive sacrificielle est faite d'un matériau dont la tendance à l'ionisation est supérieure à celle du premier métal.
