Abstract
(EN)
Provided is a solid-state battery comprising a solid-state battery layered body having a positive electrode layer, a negative electrode layer, and a solid electrolyte interposed between the positive and negative electrode layers. This solid-state battery is configured as follows: each electrode layer of the positive electrode and the negative electrode contains an active material; and among the electrode layers, an outermost electrode layer serving as the outermost layer of the solid-state battery layered body has an active material amount which differs from a non-outermost electrode layer positioned farther inward than the outermost layer.

L'invention concerne une batterie à semi-conducteurs comprenant un corps stratifié de batterie à semi-conducteurs ayant une couche d'électrode positive, une couche d'électrode négative et un électrolyte solide intercalé entre les couches d'électrode positive et négative. Cette batterie à semi-conducteurs est conçue de la manière suivante : chaque couche d'électrode de l'électrode positive et de l'électrode négative contient un matériau actif ; et parmi les couches d'électrode, une couche d'électrode la plus externe servant de couche la plus à l'extérieur du corps stratifié de batterie à semi-conducteurs a une quantité de matériau actif qui diffère d'une couche d'électrode non extérieure positionnée plus loin vers l'intérieur que la couche la plus à l'extérieur.
