Abstract
Official abstract text for this publication.
An object of the present disclosure is to provide a solid electrolyte material with excellent fluoride ion conductivity. The present disclosure achieves the object by providing a solid electrolyte material to be used for a fluoride ion battery, the solid electrolyte material comprising: a composition of BixM1−xF2+x, in which 0.4≤x≤0.9, and M is at least one kind of Sn, Ca, Sr, Ba, and Pb; and a crystal phase that has a Tysonite structure.
First claim
Opening claim text (preview).
What is claimed is: 1. A solid electrolyte material to be used for a fluoride ion battery, the solid electrolyte material comprising: a composition of Bi x M 1−x F 2+x , in which 0.4≤x≤0.9, and M is at least one kind of Sn, Ca, Sr, Ba, and Pb; and a crystal phase that has a tysonite structure with a P6 3 /mme spce group. 2. A solid electrolyte material to be use for a fluoride ion batter, the solid electrolyte material comprising: a composition of Bi x M 1−x F 2+x , in which x satisfies 0.6≤x≤0.9, and M is at least one kind of Sn, Ca, Sr, Ba, and Pb; and a crystal phase that has a tysonite structure. 3. A fluoride ion battery comprising: a cathode layer, an anode layer, and a solid electrolyte layer formed between the cathode layer and the anode layer; wherein at least one of the cathode layer, the anode layer, or the solid electrolyte layer contains the solid electrolyte material according to claim 1 . 4. A fluoride ion battery comprising: a cathode layer, an anode layer, and a solid electrolyte layer formed between the cathode layer and the anode layer; wherein at least one of the cathode layer, the anode layer, or the solid electrolyte layer contains the solid electrolyte material according to claim 2 .
