Abstract

L'invention a trait à un accumulateur électrochimique à architecture bipolaire comprenant une première (27) et deuxième plaque (73), dites plaques terminales, associées respectivement à un premier substrat collecteur de courant (35) et un deuxième substrat collecteur de courant (71), dit substrats collecteurs de courant terminaux entre lesquelles est disposé un empilement d'au moins une première cellule électrochimique (50) et une deuxième cellule électrochimique (66) dans lequel : -chacune des première et deuxième cellules électrochimiques comprend une électrode positive, une électrode négative et un séparateur (49, 67) comprenant un électrolyte conducteur d'ions ; -les première et deuxième cellules électrochimiques sont séparées l'une de l'autre par un substrat collecteur de courant, dit substrat bipolaire (53), qui supporte sur une première face une électrode (51) de la première cellule électrochimique et sur une deuxième face opposée à la première face une électrode (65) de signe opposé de la deuxième cellule électrochimique, caractérisé en ce que chacune des première et deuxième cellules électrochimiques sont logées dans un espace délimité intérieurement par un cadre traversé par un canal d'alimentation permettant l'alimentation de la cellule en électrolyte, le substrat collecteur de courant bipolaire étant enserré via un bord libre entre le cadre de la première cellule et le cadre de la deuxième cellule et coopérant avec chacun d'eux par l'intermédiaire d'au moins un joint d'étanchéité et l'accumulateur comprend en outre des moyens de serrage du cadre de la première cellule contre le cadre de la deuxième cellule.The invention relates to an electrochemical accumulator with bipolar architecture comprising a first (27) and second plate (73), called end plates, respectively associated with a first current collector substrate (35) and a second current collector substrate (71 ), said terminal current-collecting substrates between which is disposed a stack of at least a first electrochemical cell (50) and a second electrochemical cell (66) in which: each of the first and second electrochemical cells comprises a positive electrode, a negative electrode and a separator (49, 67) comprising an ion conductive electrolyte; -the first and second electrochemical cells are separated from each other by a current collecting substrate, said bipolar substrate (53), which supports on a first face an electrode (51) of the first electrochemical cell and on a second face opposite to the first face an electrode (65) of opposite sign of the second electrochemical cell, characterized in that each of the first and second electrochemical cells are housed in a space delimited internally by a frame crossed by a supply channel allowing the 'supplying the cell with electrolyte, the bipolar current-collector substrate being clamped via a free edge between the frame of the first cell and the frame of the second cell and cooperating with each of them via at least one seal and the accumulator further comprises means for clamping the frame of the first cell against the frame of the second cell.
