Patent

CA 2482864

The invention provides an EC bundle having a plurality of cells. In turn, each cell respectively comprises: a pair of sheet-like electrodes; electrolyte interposed between the electrodes; and a sheet-like current collecting element. The sheet-like current collecting element, which includes a pair of generally opposite main faces, projects from at least one of the sheet-like electrodes and is electrically connected thereto. Moreover, the plurality of cells are arranged into a stack such that their respective sheet-like current collecting elements are in a side-by-side relationship with their main faces generally facing one another. The EC bundle further comprises a current collecting terminal featuring apart relationship which define a recess which receives the sheet-like current collecting elements and which establishes an electrical connection with them. The arms of the current collecting terminal overlap at least a portion of a main face of one of the sheet-like current collecting elements.

La présente invention a trait à un groupe électrochimique comportant une pluralité de cellules. Chaque cellule, à son tour, comprend respectivement : une paire d'électrodes minces ; de l'électrolyte interposé entre les électrodes ; et un élément mince de prise de courant. L'élément mince de prise de courant, qui comporte une paire de faces principales globalement opposées, se trouve en saillie à partir d'au moins une des électrodes minces et y est électriquement relié. En outre, la pluralité de cellules sont disposées en un empilement de sorte que leurs éléments minces respectifs de prise de courant sont en relation adjacente avec leurs faces principales globalement opposées. Le groupe électrochimique comporte en outre une borne de prise de courant présentant une relation espacée définissant un évidement qui reçoit les éléments minces de prise de courant et qui établit une connexion électrique avec eux. Les bras de la borne de prise de courant recouvrent au moins une portion de la face principale d'un des éléments minces de prise de courant.
