Anode layer for fluoride ion battery and fluoride ion battery
An object of the present disclosure is to provide an anode layer for a fluoride ion battery in which decomposition of a binder is restrained. The present disclosure attains the object by providing an anode layer to be used for a fluoride ion battery, the anode layer comprising an anode active material and a non-fluorine-based binder having aromaticity.
1. A fluoride ion battery comprising a cathode layer, an anode layer, and an electrolyte layer formed between the cathode layer and the anode layer, wherein
the anode layer comprises an anode active material and a non-fluorine-based binder having aromaticity, and
the anode active material is configured to react with a fluoride ion.
2. The fluoride ion battery according to claim 1 , wherein the non-fluorine-based-binder is polyimide resin.
3. The fluoride ion battery according to claim 2 , wherein the anode active material is a simple substance of metal, an alloy, a metal oxide, or a fluoride thereof.
4. The fluoride ion battery according to claim 2 , wherein the anode active material contains at least one metal element selected from the group consisting of La, Ca, Al, Eu, Li, Si, Ge, Sn, In, V, Cd, Cr, Fe, Zn, Ga, Ti, Nb, Mn, Yb, Zr, Sm, Ce, Mg, and Pb.
5. The fluoride ion battery according to claim 2 , wherein the anode active material contains at least Fe element.
6. The fluoride ion battery according to claim 2 , wherein the anode active material is a carbon material, a polymeric material, or a fluoride thereof.
7. The fluoride ion battery according to claim 1 , wherein the anode active material is a simple substance of metal, an alloy, a metal oxide, or a fluoride thereof.
8. The fluoride ion battery according to claim 1 , wherein the anode active material contains at least one metal element selected from the group consisting of La, Ca, Al, Eu, Li, Si, Ge, Sn, In, V, Cd, Cr, Fe, Zn, Ga, Ti, Nb, Mn, Yb, Zr, Sm, Ce, Mg, and Pb.
9. The fluoride ion battery according to claim 1 , wherein the anode active material is a carbon material, a polymeric material, or a fluoride thereof.
