Method for the synthesis of sulfonylimidides having the formula M((RSO2)2N)y, wherein M is a metal or an ammonium radical quaternary or not, the Rs, which may be identical or similar are organic monovalent radicals, particularly hydrocarbyles and preferably perfluorohydrocarbyles, in C1 to C12, and y is the valence of M. On the one hand, silazane component selected amongst the silazane compounds M(((R2)3Si)2N)y or the associations of a silazane derivative A((R2)3Si)2N or a fluoride M1Fz of low cross-linking energy is reacted with, on the other hand, at least one sulfonic halogenite component consisting of a sulfonyl fluoride RSO2F or in the association of a sulfonyl chloride RSO2Cl with a fluoride M1Fz, M, R and y having the above-mentioned significations, M being selected amongst the Ms and being optionally identical to M, z being the valence of M1 and R2 representing an alkyl in C1 to C4. The imidides obtained for which the R2 are perfluorated radicals and M is an alkaline metal such as Li are usable in association with polyethers for the production of materials of the ionic conduction type for all solid generators in thin films.
