Abstract

L'invention a trait à un ensemble emballage de batterie composé de structures barrière (15) en plastique souple qui sont utilisées pour des éléments de batterie (10) ou des batteries d'alimentation, et ce, en vue de protéger les composants de la batterie de la contamination extérieure. Un ou plusieurs éléments de batterie ou une ou plusieurs batteries d'alimentation sont emballés entre les structures barrière, qui peuvent être réalisées à partir d'une matière laminée ou extrudée, et assemblés au moyen d'un soudage thermique. Chaque structure barrière comporte au moins une première couche (16), qui est une couche d'étanchéité; une seconde couche (17), qui est une couche barrière à la vapeur d'eau; une troisième couche (18), qui est une couche barrière à l'oxygène; et une couche externe (19), qui peut être du même type que l'une des autres couches ou bien une couche séparée assurant une résistance mécanique accrue à l'emballage.
