Abstract
A main object of the present disclosure is to provide an anode material that is used in a fluoride ion battery of a car and can prevent the decrease in operating voltage while inhibiting occurrence of short circuit. The present disclosure achieves the object by providing a car including a fluoride ion battery, wherein the fluoride ion battery comprises a cathode layer, an anode layer, and a solid electrolyte layer formed between the cathode layer and the anode layer. The anode layer contains an anode material comprising a Mg metal powder and a fluoride ion conductive material comprised of Ca1-xBaxF2 in which x satisfies 0.5≤x≤0.60.
Claims6
A car, wherein the car has mounted therein a fluoride ion battery, wherein the fluoride ion battery comprises a cathode layer, an anode layer, and a solid electrolyte layer formed between the cathode layer and the anode layer;
- wherein
- the anode layer contains an anode material comprising:
- a Mg metal powder;
- and
- a fluoride ion conductive material comprised of Ca1-xBaxF2 in which x satisfies 0.5≤x≤0.60.
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
- the anode layer contains an anode material comprising:
- a Mg metal powder;
- a fluoride ion conductive material comprised of Ca1-xBaxF2 in which x satisfies 0.5≤x≤0.6;
- and
- a solid electrolyte in the solid electrolyte layer is Ca1-xBaxF2 in which 0<x<1;
- and
- wherein an ion conductivity of a solid electrolyte in the solid electrolyte layer is more than an ion conductivity of the fluoride ion conductive material in the anode layer.
