Abstract
Official abstract text for this publication.
Provided is a fluoride ion secondary battery having a capacity larger than that of a conventional one. The fluoride ion secondary battery has a negative electrode including zirconium fluoride as a negative electrode active material. The zirconium fluoride may be in the form of particles with an average particle size of 100 nm or less, and the negative electrode may have a zirconium fluoride content of less than 50 % by mass. The negative electrode active material may further include metallic zirconium, which may be in the form of particles with an average particle size of 75 μm or less. The negative electrode may have a metallic zirconium content of 8% by mass or less.
First claim
Opening claim text (preview).
What is claimed is: 1 . A negative electrode for use in a fluoride ion secondary battery using fluoride ions as carriers, the negative electrode comprising a negative electrode active material comprising zirconium fluoride and metallic zirconium, wherein the zirconium fluoride has an average particle size of 100 nm or less, the metallic zirconium has an average particle size of 2 μm or more and 75 μm or less, and the negative electrode for use in a fluoride ion secondary battery has a zirconium fluoride content of less than 50% by mass and a metallic zirconium content of 8% by mass or less. 2 . A fluoride ion secondary battery comprising the negative electrode according to claim 1 . 3 . A negative electrode for use in a fluoride ion secondary battery using fluoride ions as carriers, the negative electrode comprising a negative electrode active material comprising zirconium fluoride and metallic zirconium, the negative electrode for use in a fluoride ion secondary battery having a zirconium fluoride content of less than 50% by mass and a metallic zirconium content of 8% by mass or less. 4 . A fluoride ion secondary battery, having the negative electrode for use in a fluoride ion secondary battery according to claim 3 .
