Abstract

La présente invention concerne un module de cellule électrochimique, comprenant un support présentant un niveau élevé d'utilisation générale, et un support approprié à une utilisation avec ce module électrochimique. Dans un support (5), quatre renfoncements d'assemblage de partie d'extrémité (28A-28D) sont formés, de façon à être entourés par une partie de paroi inférieure (21) et une partie de paroi périphérique (22) en vue de s'assembler avec les parties d'extrémité de quatre condensateurs au lithium ion (13A-13D). Les quatre renfoncements d'assemblage de partie d'extrémité (28A-28D) sont pourvus de renfoncements de réception de cale d'espacement (30A-30D) qui reçoivent des cales d'espacement tampon (29), lesquelles sont disposées en état comprimé entre des barres omnibus (17-20) et la partie de paroi inférieure (21) dans la partie inférieure des renfoncements.
