Abstract:
1. A layered solid-state battery comprising: at least first and second unit cells each of which includes a positive electrode layer, a solid electrolyte layer, and a negative electrode layer that are sequentially stacked; and an internal collection layer disposed such that a first side surface thereof is in contact with the positive electrode layer of the first unit cell and a second side surface thereof is in contact with the negative electrode layer of the second unit cell so as to intervene between the first and second unit cells, wherein the internal collection layer contains an electron conductive material and an ion-conductively insulating specific conductive material, wherein the ion-conductively insulating specific conductive material has a structure similar to that of a solid electrolyte material contained in at least one layer selected from the positive electrode layer and the negative electrode layer, and wherein the ion-conductively insulating specific conductive material contains a lithium-containing phosphoric acid compound having a NASICON structure.
