Abstract:
A process for preparing a solid composite electrolyte comprising at least one compound of the BIMEVOX family, which process comprises:a) at least one step of preparing a mixture of one or more compounds of the BIMEVOX family with one or more chemically inert compounds, selected from the group consisting of carbides, nitrides and oxides;b) at least one step of compacting the mixture obtained from step a); andc) at least one sintering step during which the temperature reached, over a nonzero time interval, has a value greater than the optimum sintering temperature for said compound of the BIMEVOX family;wherein said one or more compounds of the BIMEVOX family is an oxide derived from Bi.sub.4 V.sub.2 O.sub.11.
