Solid electrolyte battery and process for producing solid electrolyte battery
View Patent ↗A solid electrolyte battery using a solid electrolyte capable of realizing high conductivity, and a process for producing a solid electrolyte battery are provided. The solid electrolyte battery is structured as a laminate of a positive electrode collector layer, a positive electrode active material layer, a solid electrolyte layer, a negative electrode active material layer, and a negative electrode collector layer formed in order on a substrate. The solid electrolyte layer is a thin film formed of a compound of the formula Li 3 M0 4 (M =V, Nb, Ta, or Db).
1. A solid electrolyte battery comprising:
a positive electrode layer and a negative electrode layer; and
a solid electrolyte layer contacting both the positive electrode layer and the negative electrode layer, the solid electrolyte layer being a single layer formed of a compound of the formula Li 3 MO 4 , wherein M is selected from the group consisting of Nb, Ta, and Db, and the single layer being at least partially in an amorphous phase.
2. The solid electrolyte battery of claim 1 , wherein the single layer is an amorphous single phase.
3. A solid electrolyte battery comprising:
a positive electrode layer and a negative electrode layer; and
a solid electrolyte layer contacting both the positive electrode layer and the negative electrode layer, the solid electrolyte layer being a nitrogen-containing single layer that includes nitrogen added to a compound of the formula Li 3 MO 4 , wherein M is selected from the group consisting of Nb, Ta, or Db, and the nitrogen-containing single layer being at least partially in an amorphous phase.
4. The solid electrolyte battery of claim 3 , wherein the nitrogen-containing single layer is an amorphous single phase.
