Abstract: A current blocking element is provided. The current blocking element includes a first electrode layer, an ion conductive layer, and a second electrode layer, which are laminated in this order, wherein the first electrode layer is configured to hold ions; the ion conductive layer has ionic conductivity and does not have electronic conductivity; and the second electrode layer is configured to hold ions. Ions held in the first electrode layer are moved to the second electrode layer when current is configured to flow between the first electrode layer and the second electrode layer. Current flow between the first electrode layer and the second electrode layer is blocked when ions held in one of the first and second electrode layers are depleted saturated.

Abstract: An all-solid-state battery that includes a positive electrode, a negative electrode, and an electrolyte layer. At least one of the positive electrode, the negative electrode, and the electrolyte layer includes a lithium ion conductor having an exothermic peak in a differential thermal analysis. The ionic conductivity on the side of the temperature higher than the rising temperature of the exothermic peak is lower than the ionic conductivity on the side of the temperature lower than the rising temperature of the exothermic peak.
