Embodiment 1
[0383] In this example, a solid composition for making a composition such as Li 6.3 La 3 Zr 1.3 Sb 0.5 Ta 0.2 o 12 The solid electrolyte shown.
[0384] First, triisopropoxylanthanum as a source of lanthanum, zirconium tetrabutoxide as a source of zirconium, antimony tributoxide as a source of antimony, and tantalum pentaethoxide as a source of tantalum were prepared according to the formula shown in Table 1. Mix in proportion to obtain a mixture. This mixture was mixed with 2-n-butoxyethanol as a solvent at a predetermined ratio to obtain a metal compound solution as a mixed solution in which each raw material compound was dissolved.
[0385] The metal compound solution obtained as a mixed solution obtained above was put into a beaker made of titanium, and the first heat treatment was performed in the air at 140° C. for 20 minutes in this state to obtain a gel-like composition.
[0386] Next, a second heat treatment at 540° C. for 20 minutes was applied to the gel-like...
