Abstract
An accumulator with a bipolar architecture that comprises two terminal current collectors, between which a stack of n electrochemical cells is disposed, with n being an integer at least equal to 2, wherein: —each electrochemical cell comprises a positive electrode, a negative electrode and an ion conducting membrane that is interposed between the positive electrode and the negative electrode and comprises a liquid electrolyte included in the electrodes and the ion conducting membrane; —the n electrochemical cells are separated from each other by n−1 bipolar current collectors; wherein the positive electrode and the negative electrode of each electrochemical cell are gel electrodes comprising a composite material comprising a polymeric matrix made of at least one gelling polymer (FF), an active electrode material and optionally one or more electronic conductive additives, the polymeric matrix trapping the liquid electrolyte.
