Abstract
(EN)
This battery according to one embodiment of the present invention comprises a positive electrode collector, a positive electrode, a first electrolyte layer, a second electrolyte layer, a negative electrode and a negative electrode collector, in that order. The first electrolyte layer includes a first solid electrolyte material, and the second electrolyte layer includes a second solid electrolyte material, which is different from the first solid electrolyte material. The oxidation potential of the first solid electrolyte material is greater than the oxidation potential of the second solid electrolyte material. The first electrolyte layer is disposed so as to cover the positive electrode while in contact with the positive electrode collector, and/or so as to cover the second electrolyte layer while in contact with the negative electrode collector.

Selon un mode de réalisation, la présente invention concerne une batterie qui comprend un collecteur d'électrode positive, une électrode positive, une première couche d'électrolyte, une seconde couche d'électrolyte, une électrode négative et un collecteur d'électrode négative, dans cet ordre. La première couche d'électrolyte comprend un premier matériau d'électrolyte solide, et la seconde couche d'électrolyte comprend un second matériau d'électrolyte solide, qui est différent du premier matériau d'électrolyte solide. Le potentiel d'oxydation du premier matériau d'électrolyte solide est supérieur au potentiel d'oxydation du second matériau d'électrolyte solide. La première couche d'électrolyte est disposée de manière à recouvrir l'électrode positive tout en étant en contact avec le collecteur d'électrode positive, et/ou de manière à recouvrir la seconde couche d'électrolyte tout en étant en contact avec le collecteur d'électrode négative.
