Abstract

To provide a fluoride ion secondary battery in which high charge-discharge efficiency can be obtained even in an environment where the oxygen concentration exceeds 2 ppm.SOLUTION: A fluoride ion secondary battery includes a positive electrode material layer, a negative electrode material layer, a solid electrolyte layer disposed between the positive electrode material layer and the negative electrode material layer, and an exterior body that accommodates and seals the positive electrode material layer, the negative electrode material layer, and the solid electrolyte layer, and a sealed space in the exterior body is an Ar atmosphere. The oxygen concentration in the sealed space within the exterior body may be 7.3 ppm or less.SELECTED DRAWING: Figure 6
