Abstract

La présente invention concerne un accumulateur du type sachet et son procédé de fabrication, l'accumulateur permettant à des couches métalliques, situées au niveau des bords de feuilles stratifiées dans un sachet supérieur et un sachet inférieur, de se faire face et d'être soudées sans application de chaleur de manière à former une partie d'étanchéité, une partie de scellement de circonférence extérieure de sachet étant formée par le soudage des couches métalliques, et la présente invention a ainsi pour effet de réduire encore ou d'empêcher la possibilité de pénétration d'humidité depuis l'extérieur et la possibilité de fuite d'électrolyte hors de l'accumulateur.
