Abstract
(EN)
This layered battery is provided with: an exterior body having a first base material which includes a metal layer and a resin adhesive layer, a second base material opposing the first base material, and a seal part which heat-seals the first and second base materials and forms a sealing space between the first and second base materials; a membrane electrode joined body; and a first tab that is electrically connected to a first connection of the membrane electrode joined body and that extends to the outside of the exterior body through the seal part of the exterior body. The layered battery is further provided with first short-circuiting prevention layers that are provided to the surface of the first connection of the membrane electrode joined body on the first base material side and to the surface of the first tab on the first base material side. The maximum thickness of the first short-circuiting prevention layer in the first tab is different from that of the first short-circuiting prevention layer in the first connection.

L'invention concerne une batterie en couches comprenant : un corps extérieur ayant un premier matériau de base qui comprend une couche métallique et une couche adhésive de résine, un second matériau de base opposé au premier matériau de base et une partie d'étanchéité qui scelle thermiquement les premier et second matériaux de base et forme un espace d'étanchéité entre les premier et second matériaux de base ; un corps assemblé d'électrode à membrane ; et une première languette qui est électriquement connectée à une première connexion du corps assemblé d'électrode à membrane et qui s'étend vers l'extérieur du corps extérieur à travers la partie d'étanchéité du corps extérieur. La batterie en couches est en outre pourvue de premières couches de prévention de court-circuit qui sont disposées sur la surface de la première connexion du corps assemblé d'électrode à membrane sur le côté du premier matériau de base et sur la surface de la première languette sur le côté du premier matériau de base. L'épaisseur maximale de la première couche de prévention de court-circuit dans la première languette est différente de celle de la première couche de prévention de court-circuit dans la première connexion.
