  • Tetrakis trialkyl siloxy alanates of alkali metals, their solid solutions with plastic materials and their use for the constitution of conductor elements for electrochemical generators
    Patent number: 4556616
    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[AlO.sub.4 (SiR.sub.3).sub.4 ].sup.- M.sup.+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.
    Type: Grant
    Filed: June 1, 1983
    Date of Patent: December 3, 1985
    Assignees: Agencie Nationale de Valorisation de la Recherche, Societe Nationale Elf Aquitaine
    Inventors: Michel B. Armand, Fouzia El Kadiri Cherkaoui el Moursli
  • Tetra-alkynyl or -aluminates of alkali metals, their solid solutions with plastic materials and their use for the constitution of conductor elements for electrochemical generators
    Patent number: 4542081
    Abstract: The invention relates to solid solutions constituted by one or several ionic compounds of the formula:(R--C.tbd.C).sub.4 X.sup.-, M.sup.+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.

  • Bis perhalogenoacyl -or sulfonyl-imides of alkali metals, their solid solutions with plastic materials and their use to the constitution of conductor elements for electrochemical generators
    Patent number: 4505997
    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.sub.2 group and M is an alkali metal.
