Abstract
A method for producing an anion-containing inorganic solid material includes: a laminating step of forming a laminate including an electrode, a solid electrolyte layer, and a doping target layer containing a material to be doped; and a doping step of doping the material to be doped with an anion using the doping target layer as a reaction field by applying a voltage to the laminate to have a potential of the doping target layer to be higher than a potential of the electrode.
Claims18
A method for producing an anion-containing inorganic solid material, the method comprising:
- a laminating step of forming a laminate comprising an electrode, a solid electrolyte layer, and a doping target layer containing a material to be doped;
- and
- a doping step of doping the material to be doped with an anion using the doping target layer as a reaction field by applying a voltage to the laminate to have a potential of the doping target layer to be higher than a potential of the electrode.
An apparatus for producing an anion-containing inorganic solid material, the apparatus comprising:
- a housing portion comprising a bottom wall portion and a sidewall portion, the housing portion being conductive and configured to house a laminate comprising an electrode, a solid electrolyte layer, and a doping target layer containing a material to be doped;
- a conductive member disposed to face the bottom wall portion of the housing portion, the conductive member configured to press the laminate in a laminating direction of the laminate;
- and
- a voltage applying unit configured to apply a voltage between the conductive member and the housing portion to have a potential of the conductive member to be higher than a potential of the housing portion.
