    Abstract: A nonpolar all-solid-state battery that includes a first electrode; a second electrode; and a solid electrolyte layer the first electrode and the second electrode. Each of the first electrode and the second electrode includes a first active material and at least one second active material. The first active material functions as both a positive electrode active material and a negative electrode active material. The first active material has a larger specific capacity when functioning as the positive electrode active material than when functioning as the negative electrode active material. In each of the first electrode and the second electrode, a ratio of the first active material to a total amount of the first and second active materials is more than 50% by mass and less than 100% by mass. A mass of each of the first and second active materials is equal between the first electrode and the second electrode.

    Abstract: A layered solid-state battery that includes a first unit cell, a second unit cell, and an internal collection layer that is disposed to intervene between the unit cells. Each of the unit cells includes a positive electrode layer, a solid electrolyte layer, and a negative electrode layer that are sequentially stacked. The internal collection layer has one side surface that is in contact with the positive electrode layer of the first unit cell and the other side surface that is in contact with the negative electrode layer of the second unit cell. Also, the internal collection layer contains an electron conductive material and an ion-conductively insulating specific conductive material.

    Abstract: Provided is an all solid state battery which has the same level of discharge capacity as in the case of using an electrolyte solution, and is able to improve the cycle stability. An all solid state battery includes a solid electrolyte layer, as well as a positive electrode layer and a negative electrode layer provided in positions opposed to each other with the solid electrolyte layer interposed therebetween. At least one of the positive electrode layer and the negative electrode layer is bonded to the solid electrolyte layer by firing. The negative electrode layer contains an electrode active material composed of a metal oxide containing no lithium, and a solid electrolyte containing no titanium.
