Claims5
A solid electrolyte represented by the following formula (1):
- Li7−yLa3 (Zr2−x−yGexMy) O12 (1)
- wherein 0.00<x≤0.40, 0.00<y≤1.50, M is Sb or is Sb and an element of at least one of Nb and Ta.
A method for producing a solid electrolyte comprising:
- a mixing step for mixing a plurality of raw materials to obtain a mixture, the plurality of raw materials including a metal element included in the following formula (1),
- a first heating step for subjecting the mixture to a first heat treatment to form a calcined body,
- and a second heating step for subjecting the calcined body to a second heat treatment to form a crystalline solid electrolyte represented by the following formula (1):
- Li7−yLa3 (Zr2−x−yGexMy) O12 (1)
- wherein 0.00<x≤0.40, 0.00<y≤1.50, M is Sb or is Sb and an element of at least one of Nb and Ta.
