Document Type and Number:

Japanese Patent JP7243704

Kind Code:

B2

Abstract:

The all-solid-state secondary battery of the disclosure comprises a positive electrode collector layer, a positive electrode layer, a solid electrolyte layer, a negative electrode layer and a negative electrode collector layer stacked in that order, wherein the positive electrode layer has a positive electrode active material layer and an insulating layer disposed around the perimeter edges of the positive electrode active material layer, and when the all-solid-state secondary battery is viewed from the stacking direction, the outer edges of the positive electrode active material layer on the solid electrolyte layer side are further inward than the outer edges of the positive electrode active material layer on the positive electrode collector layer side, and the outer edges of the positive electrode collector layer are further inward than the outer edges of the positive electrode active material layer on the positive electrode collector layer side.
