Abstract

The main object of the present invention is to provide an active material that has a favorable cycle property. The present invention achieves the object by providing an active material to be used for a fluoride ion battery comprising a crystal phase having a layered perovskite structure, and represented by A n+1 B n O 3n+1−α F x (A is composed of at least one of an alkaline earth metal element and a rare earth element; B is composed of at least one of Mn, Co, Ti, Cr, Fe, Cu, Zn, V, Ni, Zr, Nb, Mo, Ru, Pd, W, Re, Bi, and Sb; “n” is 1 or 2; “α” satisfies 0≤α≤2; and “x” satisfies 0≤x≤2.2).

First claim

What is claimed is:

1. A fluoride ion battery comprising
a cathode active material layer containing a cathode active material,
an anode active material layer containing an anode active material, and
an electrolyte layer formed between the cathode active material layer and the anode active material layer, wherein the cathode active material or the anode active material is an active material comprising a crystal phase having a layered perovskite structure, and represented by A n+1 B n O 3n+1−α F x , wherein A is composed of at least one of an alkaline earth metal element and a rare earth element; B is composed of at least one of Mn, Co, Ti, Cr, Fe, Cu, Zn, V, Ni, Zr, Nb, Mo, Ru, Pd, W, Re, Bi, and Sb; “n” is 1 or 2: “α” satisfies 0≤α≤2, and “x” satisfies 0≤x≤2.2.

2. The fluoride ion battery according to claim 1 , wherein A is selected from the group consisting of at least one of Ca, Sr, Ba, Sc, Y, La, Ce, Pr, Nd, Sm and Gd.
