Title
(EN) ARRANGEMENT OF ELECTROCHEMICAL CELLS
(FR) STRUCTURE DE PILES ELECTROCHIMIQUES
Abstract
(EN)
The application describes a method for producing a plurality of flat electrochemical cells (1), wherein the cells are arranged between sheets of flexible sealing material and a seal is made between adjacent cells. The spacing between adjacent cells (1) is chosen to be substantially equal to or slightly larger than the width of the individual cells. The application also describes a single cell (1) or a group of cells (1) formed in accordance with the above method, wherein the single cell has sealed edges each of which is substantially half the width of the cell or slightly more than half the width of the cell, or wherein the group of cells (1) has the aforementioned sealing edges and sealed areas therebetween which are substantially the same width as the cells or slightly wider than the width of the cells.
(FR)
L'invention concerne un procédé qui permet de produire une structure constituée d'une pluralité de piles électrochimiques plates (1), dans laquelle les piles sont disposées entre des plaques de matériau souple et réunies par un joint. La distance entre les piles adjacentes (1) est choisie de façon à être sensiblement égale ou légèrement supérieure à la largeur de chaque pile. L'invention concerne également une pile unique (1) ou un groupe de piles (1) formé selon ledit procédé. Une pile comporte des bords scellés dont chacun a une largeur sensiblement égale ou légèrement supérieure à la moitié de celle de la pile. Dans le groupe de piles (1), lesdits bords scellés, ainsi que les zones scellées qui les séparent, ont une largeur sensiblement égale ou légèrement supérieure à celle des piles.
