First claim
Opening claim text (preview).
The invention claimed is: 1. A solid electrolyte sheet containing β-alumina and/or β″-alumina and having a thickness of 1 mm or less and a voidage of 20% or less, wherein the solid electrolyte sheet includes, in % by mole, 65 to 98% Al 2 O 3 , 2 to 20% Na 2 O, 0.3 to 10% of at least one of MgO and Li 2 O, and 1 to 15% ZrO 2 . 2. The solid electrolyte sheet according to claim 1 , having an ion conduction value of 1 S to 6.5 S. 3. A solid electrolyte sheet containing p-alumina and/or β″-alumina and having a thickness of 1 mm or less and a voidage of 20% or less, wherein the solid electrolyte sheet includes, in % by mole, 65 to 98% Al 2 O 3 2 to 20% Na 2 O, 0.3 to 10% of at least one of MgO and Li 2 O, and 0.01 to 5% Y 2 O 3 . 4. The solid electrolyte sheet according to claim 1 , wherein the solid electrolyte sheet is for use in a sodium ion all-solid-state secondary cell. 5. A sodium ion all-solid-state secondary cell including the solid electrolyte sheet according to claim 4 , a positive electrode layer formed on one side of the solid electrolyte sheet, and a negative electrode layer formed on the other side of the solid electrolyte sheet. 6. A solid electrolyte sheet containing β-alumina and/or β″-alumina and having a thickness of 1 mm or less and an ion conduction value of 1 S to 6.5 S, wherein the solid electrolyte sheet includes, in % by mole, 65 to 98% Al 2 O 3 , 2 to 20% Na 2 O, 0.3 to 10% of at least one of MgO and Li 2 O, and 1 to 15% ZrO 2 . 7. A solid electrolyte sheet containing p-alumina and/or β″-alumina and having a thickness of 1 mm or less and an ion conduction value of 1 S to 6.5 S, wherein the solid electrolyte sheet includes, in % by mole, 65 to 98% Al 2 O 3 2 to 20% Na 2 O, 0.3 to 10% of at least one of MgO and Li 2 O, and 0.01 to 5% Y 2 O 3 . 8. A solid electrolyte sheet containing β-alumina and/or β″-alumina and having a thickness of 1 mm or less and a voidage of 20% or less, wherein the solid electrolyte sheet includes, in % by mole, 65 to 98% Al 2 O 3 , 2 to 20% Na 2 O, 0.3 to 15% of at least one of MgO and Li 2 O, and 1 to 15% ZrO 2 or 0.01 to 5% Y 2 O 3 . 9. A solid electrolyte sheet containing β-alumina and/or β″-alumina and having a thickness of 1 mm or less and an ion conduction value of 1 S to 6.5 S, wherein the solid electrolyte sheet includes, in % by mole, 65 to 98% Al 2 O 3 , 2 to 20% Na 2 O, 0.3 to 15% of at least one of MgO and Li 2 O, and 1 to 15% ZrO 2 or 0.01 to 5% Y 2 O 3 .
