Abstract:

Provided is a fluoride ion secondary battery having a capacity larger than that of a conventional one. The fluoride ion secondary battery includes a negative electrode including Li.sub.3AlF.sub.6 as a negative electrode active material. The content of the active material Li.sub.3AlF.sub.6 in the negative electrode may be 25% by mass or less. The active material Li.sub.3AlF.sub.6 may be in an amorphous state and may be in the form of particles with an average particle size on the order of micrometers.
