Definitions

  • the memory cells of the stack are connected in parallel.
  • the memory cells are preferably stacked one behind the other in such a way that the first ones of the first current conductors of all the memory cells are arranged one behind the other and the second current collector of all memory cells are arranged one behind the other.
  • a contact element for producing an electrically conductive connection between the first and second pressure surfaces of a spacer element is in each case provided in the region of the first pressure surfaces and in the region of the second pressure surfaces of a spacer element.
  • the end face of the support elements is at least the same size, in particular larger than the end face of the contact elements. So can the Verpress later reliably absorbed and damage spacers are avoided.
  • each spacer element is formed as a substantially four-sided frame.
  • two parallel frame sides are in each case in particular formed with pressure webs with first / second or third pressure surfaces lying opposite the end face.
  • each memory cell is arranged in the stacking direction between two frames, and the distance of the spacer elements transversely to the stacking direction is fixed by the connecting the pressure bridges frame sides. Therefore, the stack of memory cells and spacers already stabilizes during assembly itself.
  • FIG. 9 shows a frame of the cell block of FIG. 8 with contact elements in FIG
  • FIG. 6 again illustrates the sequence of the first and second current conductors 18a, 18b of the memory cells 2 and the corresponding alternately arrangement of the contact elements 26 for realizing the series connection of the memory cells 2 of the cell block 1.

Abstract

Le dispositif accumulateur d'énergie électrochimique selon l'invention comporte une pluralité de cellules accumulatrices planes (2) qui comportent chacune un premier déflecteur de courant (18a) et un second déflecteur de courant (18b) sur un côté étroit de la cellule accumulatrice (2) ; une pluralité d'éléments d'écartement (4) qui sont chacun agencés entre deux cellules accumulatrices (2) pour maintenir une distance prédéfinie entre les cellules accumulatrices (2) ; et un système de tension (10) servant à contracter les cellules accumulatrices (2) et les éléments d'écartement (4) en un empilement. Les éléments d'écartement (4) comportent chacun des deux côtés qui sont tournés vers une cellule accumulatrice (2), une première surface de pression (22a) et une seconde surface de pression (22b). En l'occurrence, l'un des déflecteurs de courant (18a, 18b) des cellules accumulatrices (2) est serré par adhérence par le système de tension (10) entre les premières surfaces de pression (22a) de deux éléments d'écartement (4) et l'autre déflecteur de courant (18b, 18a) des cellules accumulatrices (2) est serré par adhérence par le système de tension (10) entre les secondes surfaces de pression (22b) de deux éléments d'écartement (4). Dans la zone des premières surfaces de pression (22a) et/ou dans la zone des secondes surfaces de pression (22b) d'un élément d'écartement (4), le dispositif comporte à chaque fois un élément de contact (26) servant à établir une liaison électriquement conductrice entre les premières ou les secondes surfaces de pression (22a, 22b) d'un élément d'écartement (4), et enfin les éléments d'écartement (4) et/ou les éléments de contact (26) sont arrangés de telle sorte que les tassements entre les premières surfaces de pression (22a) et entre les secondes surfaces de pression (22b) s'harmonisent les uns avec les autres.
