| Claim: |
1. A solid electrolyte comprising: LiBH4; and an alkali metal compound represented by the following formula (1): MX (1) (in the formula (1), M represents an alkali metal atom, and X represents one selected from the group consisting of halogen atoms, NR2 groups (each R represents a hydrogen atom or an alkyl group) and N2R groups (R represents a hydrogen atom or an alkyl group)). |
| Claim: |
2. The solid electrolyte according to claim 1, wherein a molar ratio between the LiBH4 and the alkali metal compound is as follows: LiBH4:alkali metal compound 1:1 to 20:1. |
| Claim: |
3. The solid electrolyte according to claim 1, wherein the solid electrolyte has diffraction peaks at least in five regions of 2θ24.0±1.0 deg, 25.6±1.2 deg, 27.3±1.2 deg, 35.4±1.5 deg, and 42.2±2.0 deg in X-ray diffraction (CuKα: λ=1.5405 Å) measured below 115° C. |
| Claim: |
4. The solid electrolyte according to claim 1, wherein X in the formula (1) is any one of an iodine atom and an amino group. |
| Claim: |
5. The solid electrolyte according to claim 4, wherein the alkali metal compound is at least one selected from the group consisting of LiI, RbI, and CsI. |
| Claim: |
6. A secondary battery comprising the solid electrolyte according to claim 1. |
| Claim: |
7. A method for producing a solid electrolyte, comprising: mixing LiBH4 with an alkali metal compound represented by the following formula (1): MX (1) (in the formula (1), M represents an alkali metal atom, and X represents one selected from the group consisting of halogen atoms, NR2 groups (each R represents a hydrogen atom or an alkyl group) and NOR groups (R represents a hydrogen atom or an alkyl group)); heating the mixture, thereby melting or sintering the mixture; and then cooling the mixture. |
| Claim: |
8. The method for producing a solid electrolyte according to claim 7, wherein a temperature to which the mixture is heated is 50° C. or higher. |
| Claim: |
9. The method for producing a solid electrolyte according to claim 7, wherein a molar ratio between the LiBH4 and the alkali metal compound mixed with each other is as follows: LiBH4:alkali metal compound=1:1 to 20:1. |
| Claim: |
10. The method for producing a solid electrolyte according to claim 7, wherein X in the formula (1) is any one of an iodine atom and an amino group. |
| Claim: |
11. The method for producing a solid electrolyte according to claim 10, wherein the alkali metal compound is at least one selected from the group consisting of LiI, RbI, and CsI. |
| Claim: |
12. A method for producing a solid electrolyte comprising: heating a solid electrolyte obtained by the production method according to claim 7 at or above 115° C.; and then cooling the solid electrolyte. |
