Electric accumulator with a solid electrolyte
An electric accumulator is described that is comprised of an anode compartment containing an anode formed from at least one metal selected from the group consisting of metals belonging to groups IA, IIA, IIB, and IIIB of the periodic table of elements; a cathode compartment containing a cathode formed at least partly from a conducting member comprising a substance capable of accepting electrons, to form anions by cathodic reduction, and an electrolyte consisting of a substance capable of dissolving the product or products generated during discharge of the accumulator, said electrolyte being maintained in a molten state; the anode compartment and cathode compartment being separated from each other by a wall impervious to fluids and formed from a solid mineral electrolyte capable of allowing selective migration of the anode metal in the form of cations; wherein the anode compartment contains a porous matrix adjacent to the anode and at least one salt of the anode metal capable of allowing migration of this metal in the form of cations, said salt being maintained in a molten state and permeating said porous matrix, with said salt and said matrix being interposed between the anode and said separation wall, and wherein said anode metal salt is selected from the group consisting of compounds of the two general formulas: Me(Br/sub 4/)N and Me(AlR/sub 4/)N (in which Me represents a metal selected from the group consisting of metals belonging to groups IA, IIA, IIB, and IIIB of the periodic table of elements, R represents an alkyl or aryl group, and N is 1, 2 or 3, according to the valency of the metal Me) and mixtures of at least two of these compounds.
