Abstract

La présente invention concerne un procédé permettant de produire une bande d'alliage de plomb destinée à la fabrication des anodes et des cathodes d'un accumulateur au plomb. Ce procédé consiste à extruder un alliage de plomb à une température élevée de manière à produire une bande d'alliage de plomb présentant un profil désiré, puis à refroidir rapidement la bande extrudée afin d'obtenir une microstructure souhaitée. Les grilles d'accumulateurs produites à partir de cette bande d'alliage de plomb présentent une croissance verticale réduite et une meilleure résistance à la corrosion.
