Abstract

Abstract The invention relates to novel ionic compounds which can be incorporated in polymers whose monomer units include at least one hetroatom, particularly oxygen or nitrogen adapted to form bonds of the donor-acceptor type with the cation of the ionic compound, the solid solutions obtained being utilizable to form the electrolyte of an electrochemical generator. These ionic compounds are represented by the formula (C.sub.n X.sub.2n+1 Y).sub.2 N.sup.-,M.sup.+ in which : X is a halogen, n varies from 1 to 4, Y is a CO or SO 2 group and M is an alkali metal.
