(FR) CELLULE ELECTROCHIMIQUE
Abstract
(EN) A high temperature rechargeable electrochemical cell (10) is provided, comprising a housing (12) divided by a pair of concentric separator tubes (18, 20) into two anode compartments each containing molten alkali metal active anode material, the alkali metal in each anode compartment being electronically connected to the alkali metal in the other anode compartment, and a cathode compartment sandwiched between the anode compartments. The cathode compartment contains cathode material comprising a porous electrolyte-permeable electronically conductive matrix with a charged state in which it has a transition metal halide active cathode material dispersed therein, the matrix being impregnated with molten salt electrolyte. The cell comprises a cathode current collector tube (64) located between the separator tubes, so that an inner part of the cathode is located between the smaller separator tube and the current collector tube, an outer part of the cathode being located between the current collector tube and the larger separator tube.
(FR) Cellule électrochimique rechargeable (10) à haute température, comportant une cuve (12) partagée par une paire de tubes séparateurs concentriques (18, 20) en deux compartiments anodiques dont chacun renferme une matière anodique active en fusion à base de métal alcalin, le métal alcalin de chaque compartiment anodique étant relié par voie électronique au métal alcalin de l'autre compartiment anodique, ainsi qu'un compartiment cathodique intercalé entre les compartiments anodiques. Le compartiment cathodique renferme une matière cathodique comportant une matrice poreuse à conductivité électronique et perméable à l'électrolyte, cette matrice ayant un état chargé dans lequel elle renferme une matière cathodique active dispersée à base d'halogénure de métal de transition, et étant imprégnée d'un sel électrolyte en fusion. Ladite cellule comporte un tube collecteur de courant cathodique (64) placé entre les tubes séparateurs de sorte qu'une partie interne de la cathode se situe entre le tube séparateur relativement petit et le tube collecteur de courant, une partie externe de la cathode se situant entre le tube collecteur de courant et le tube séparateur relativement grand.
