TETRAALKYNYL BORATES OR ALUMINATES OF ALKALI METALS, THEIR SOLID SOLUTIONS WITH PLASTIC MATERIALS AND THEIR USE IN FORMING CONDUCTIVE ELEMENTS FOR ELECTROCHEMICAL GENERATORS

摘要

The invention relates to solid solutions constituted by one or several ionic compounds of the formula: (R-C 3BOND C)4X-, M+ in which: X is a trivalent element liable of entering into 4-coordination; the groups R are aprotic hydrocarbon radicals, that is to say radicals which are non proton donors; M is an alkali metal; entirely dissolved within a macromolecular material formed at least in part by a polymer the monomer units of which include at least one hetero-atom, adapted to form bonds of the donor-acceptor type with the cation of the ionic compound. These solutions can be used for the constitution of solid electrolyte materials of electrochemical generators.
