Abstract
Abstract The invention relates to novel ionic compounds incorporable with polymers of which the monomer units comprise at least one hetero-atom, 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 useful for forming the electrolyte of an electrochemical generator. These ionic compounds are represented by the formula [AlO4(SiR3)4]-M+ in which the groups R are aprotic hydrocarbon radicals, that is to say radicals which are non-donors of protons, and M is an alkali metal.
