| 摘要 |
A lithium ion conductive substance is provided that is characterized by containing a compound wherein a composite oxide represented by Li1+x+yAlxTi2-xSiyP3-yO12 (0≦x≦1 and 0≦y≦1) is doped with at least one kind of element selected from Zr, Hf, Y, and Sm. Furthermore, a method for manufacturing the lithium ion conductive substance is provided that includes the following steps: (a) a step of forming an inorganic substance that contains predetermined quantities of a Li component, an Al component, a Ti component, a Si component, and a P component, into a sheet shape, and (b) a step of interposing between materials that contain at least one kind of element selected from Zr, Hf, Y, and Sm, and sintering, a sheet-shaped formed body obtained at step (a). |

1. A lithium ion conductive substance comprising:
a compound including a composite oxide represented by Li1+x+yAlxTi2-xSiyP3-yO12 doped with at least one element selected from a group consisting of Zr, Hf, Y, and Sm, where 0≦x≦0.4 and 0<y≦0.6, wherein a raw material of the lithium ion conductive substance includes an inorganic substance including a Li component, an Al component, a Ti component, a Si component, and a P component, and is generated by a process including preparing a raw material mixture including an Li-containing compound, an Al-containing compound, a Ti-containing compound, an Si-containing compound, and a P-containing compound, wherein the raw material mixture includes at least one compound that is a carbonate and at least one other compound that is ammonium salt; first heating the raw material mixture to a temperature that is higher than or equal to a decomposition initiation temperature of the ammonium salt and lower than a decomposition initiation temperature of the carbonate, and subsequently cooling the raw material mixture to room temperature, to generate a product containing each of the components at composition ratios expressed in oxide equivalents that are 15 mol % or more and 30 mol % or less for Li2O, 1 mol % or more and 10 mol % or less for Al2O3, 30 mol % or more and 45 mol % or less for TiO2, 1 mol % or more and 10 mol % or less for SiO2, and 22 mol % or more and 40 mol % or less for P2O5; first milling the product into a milled product; second heating the milled product to a temperature higher than or equal to the decomposition initiation temperature of the carbonate and lower than or equal to 800° C., and subsequently cooling the milled product to room temperature; and second milling the heated and subsequently cooled milled product into the inorganic substance. |
