Abstract
La présente invention concerne une batterie, comprenant : un boîtier, renfermant une cavité, le boîtier comprenant une première plaque latérale ; et une cellule, située dans la cavité. Le côté de la cellule faisant face à la première plaque latérale est pourvu d'une première languette et d'une partie d'extension s'étendant vers la première plaque latérale, et la distance entre le côté de la première languette relié à la cellule et la première plaque latérale est supérieure à la distance entre la partie d'extension et la première plaque latérale. La présente invention permet d'améliorer des performances telles que la densité d'énergie de la batterie.
