Abstract

Cellule pour accumulateur à arrangement optimisé L’invention se rapporte à une cellule (1) pour accumulateur comprenant une pochette (11) à l’intérieur de laquelle des électrodes (2) et des films séparateurs (3) sont arrangés sous la forme de : une pluralité d’électrodes (2) sensiblement planes, positives et négatives, disposées en alternance selon deux groupes respectifs déterminés par polarité, chacun comprenant une languette (21) de contact respective disposée à une des extrémités des électrodes (2),des films séparateurs (3) plans positionnés entre chacune des électrodes (2), caractérisé en ce que les languettes (21) de contact respectives des électrodes (2) traversent l’épaisseur de la pochette (11) et sont repliées contre celle-ci, de sorte que les languettes (21) de contact des électrodes (2) positives sont au niveau d’une surface (111) externe de la pochette (11) opposée à la surface (112) externe contre laquelle les languettes (21) de contact des électrodes (2) négatives sont repliées.
