Fluoride ion battery and method for producing fluoride ion battery

A fluoride ion battery comprising:

• an electrode layer that includes a first metal element or a carbon element and has capability of fluorination and defluorination;
• a solid electrolyte layer containing a solid electrolyte material, the solid electrolyte material including a second metal element with lower fluorination potential and defluorination potential than the potentials of the first metal element or the carbon element;
• and
• an anode current collector, in this order;
• and
• a fluoride layer containing a fluoride of the first metal element or the carbon element on a surface, that is the anode current collector side, of the electrode layer;
• and
• an anode active material layer containing a simple substance of the second metal element on a surface, that is the anode current collector side, of the solid electrolyte layer, and
• the anode current collector includes a simple substance of Pb, Sn, In, Bi, or Sb, or an alloy containing one or more of these metal elements;
• and wherein the anode current collector is directly disposed on a surface of the solid electrolyte layer prior to charging the battery.
