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 An+1BnO3n+1−αFx (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).
Claims2
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 An+1BnO3n+1−αFx, 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.
