Li7-x(La3-zYz)(Zr2-xMx)O12 (1) In the formula (1), x and z satisfy 0.00<x<1.10, and 0.00<z≤0.15, and M is two or more types of elements selected from the group consisting of Nb, Ta, and Sb.
Claims5
A solid electrolyte, represented by the following compositional formula (1):
- Li7-x(La3-zYz)(Zr2-xMx)O12 (1)
- wherein x and z satisfy 0.00<x<1.10, and 0.00<z≤0.15, and M is two or more types of elements selected from the group consisting of Nb, Ta, and Sb.
A method for producing a solid electrolyte comprising:
- a mixing step of mixing multiple types of raw materials containing metal elements included in the following compositional formula (1), thereby obtaining a mixture;
- a first heating step of subjecting the mixture to a first heating treatment thereby forming a calcined body;
- and
- a second heating step of subjecting the calcined body to a second heating treatment thereby forming a crystalline solid electrolyte represented by the following compositional formula (1):
- Li7-x(La3-zYz)(Zr2-xMx)O12 (1)
- wherein x and z satisfy 0.00<x<1.10, and 0.00<z≤0.15, and M is two or more types of elements selected from the group consisting of Nb, Ta, and Sb.
