A solid electrolyte comprising:
- Na, Mα, Mβ, and F, where Mα is at least one element serving as a trivalent cation, and Mβ is at least one element serving as a quadrivalent or higher-valent cation.
A method producing a solid electrolyte, comprising:
- a) obtaining a mixture of Na3MαF6 and a substance that contains Na, Mβ, and F or a mixture of MαF3, NaF, and a substance that contains Na, Mβ, and F, where Mα is at least one element serving as a trivalent cation, and Mβ is at least one element serving as a quadrivalent or higher-valent cation;
- and
- b) subjecting said mixture to a mechanical milling process.
