The present invention relates to a ternary solid electrolyte composition represented by AgI- Ag2O - GeO2 . Recently, various types of solid electrolyte compositions containing Ag + ion high conductors and AgI as main components have been announced. Among these, there is a type called ion conductive glass.
By adding 30 to 50 mol% of various AgxMeyOz compounds of silver and other metal oxides to AgI, it is vitrified in a certain composition range and by performing a certain heat treatment (for example, rapid cooling treatment),
It has been announced that a solid electrolyte with ionic conductivity about one order of magnitude better than that in a crystalline state can be obtained. As a result of a detailed study of the ionic conductivity of these highly ionic conductive glasses, the present invention has revealed that the composition can be applied over a wider range of compositions, as shown in the shaded area surrounded by ABCDEFG in Figure 1, compared to previous publications. was found to have high ionic conductivity. Examples will be given below to explain the reasons for limiting the composition. Example Using commercially available AgI, Ag 2 O, and GeO 2 powders (all with a purity of 99.9% or higher) as raw materials, they were weighed to have the composition of each sample number shown in Table 1.
Mix each sample thoroughly in an agate mortar.

果を、第２表に示す。[Table] This mixed powder is placed in a quartz glass ampoule and vacuum sealed. This was heat treated at 500°C for 20 hours, then placed in liquid nitrogen for rapid cooling. Furthermore, in order to make the quenching effect more effective, the melt in the glass ampoule may be dropped onto a stainless steel plate that is being cooled with liquid nitrogen. The sample thus obtained is collected and its ionic conductivity is measured. The results of these measurements are shown in Table 2.
