A main object of the present disclosure is to provide a novel cathode active material that may be used for a fluoride ion battery. The present disclosure achieves the object by providing a cathode active material used for a fluoride ion battery, comprising a composition represented by Pb2−xCu1+xF6, wherein 0≤x<2.
First claim
Opening claim text (preview).
What is claimed is: 1. A fluoride ion battery comprising a cathode active material layer, an anode active material layer, and an electrolyte layer formed between the cathode active material layer and the anode active material layer, wherein the cathode active material layer includes a cathode active material of granular shape and comprising a composition represented by Pb 2−x Cu 1+x F 6 , wherein 0≤x<2. 2. The fluoride ion battery according to claim 1 , wherein the x satisfies x≤1.75. 3. The fluoride ion battery according to claim 1 , wherein the x satisfies 0.5≤x≤1.5. 4. The fluoride ion battery according to claim 1 , wherein the electrolyte layer is a solid electrolyte layer. 5. The fluoride ion battery according to claim 4 , wherein the cathode active material layer does not include a solid electrolyte. 6. The fluoride ion battery according to claim 4 , wherein the cathode active material layer includes only PbF 2 as a solid electrolyte. 7. A fluoride ion battery comprising a cathode active material layer, an anode active material layer, and an electrolyte layer formed between the cathode active material layer and the anode active material layer, wherein the cathode active material layer includes a cathode active material of granular shape and comprising a Pb element, a Cu element, and a F element, and the cathode active material has a peak at a position of 2θ=22.6°±0.5°, 27.8°±0.5°, 38.5°±0.5°, and 44.8°±0.5° in X-ray diffraction measurement using a CuKα ray. 8.
