Abstract
(EN) A primary objective of the present invention is to provide a solid cell with which it is possible to alleviate short-circuits between electrodes. The present invention is a solid cell, comprising a first electrode layer, a second electrode layer, and a solid electrolyte layer which is positioned between the first electrode layer and the second electrode layer. A first insulation layer is positioned upon the exterior circumference of the first electrode layer. The size of the stack face of the first electrode layer, taking the stack direction of the first electrode layer, the solid electrolyte layer, and the second electrode layer as the direction of the normal thereof, is smaller than the size of the stack face of the solid electrolyte layer. When viewed from the stack direction, the outer edge of the solid electrolyte layer is located upon the exterior circumference of the first electrode layer, and the outer edge of the first insulation layer is located on the exterior circumference of the solid electrolyte layer. The first electrode layer, the first insulation layer, and the solid electrolyte layer are positioned such that the outer edge of the first insulation layer and the end parts of the solid electrolyte layer make contact.
(FR) Un objectif principal de la présente invention est de fournir une cellule solide au moyen de laquelle il est possible de réduire les courts-circuits entre les électrodes. La présente invention a trait à une cellule solide qui comprend une première couche d'électrode, une seconde couche d'électrode et une couche d'électrolyte solide qui est placée entre la première couche d'électrode et la seconde couche d'électrode. Une première couche isolante est placée au-dessus de la circonférence extérieure de la première couche d'électrode. La taille de la face d'empilement de la première couche d'électrode, en prenant la direction d'empilement de la première couche d'électrode, de la couche d'électrolyte solide et de la seconde couche d'électrode en tant que direction de sa perpendiculaire, est inférieure à la taille de la face d'empilement de la couche d'électrolyte solide. Lorsqu'elle est vue dans la direction d'empilement, le bord extérieur de la couche d'électrolyte solide est situé au-dessus de la circonférence extérieure de la première couche d'électrode et le bord extérieur de la première couche isolante est situé sur la circonférence extérieure de la couche d'électrolyte solide. La première couche d'électrode, la première couche isolante et la couche d'électrolyte solide sont placées de manière à ce que le bord extérieur de la première couche isolante et les parties d'extrémité de la couche d'électrolyte solide soient en contact.
