Disclosed are a method of manufacturing a lead (or lead alloy) plate lattice for a lead-acid battery, featured in that a melt of lead or a lead alloy is continuously extruded under temperatures lower by 10 to 100°C than the melting point of lead or the lead alloy, followed by subjecting the extrudate to cold rolling under temperatures lower by 50 to 230°C than the melting point of lead or the lead alloy with the total draft rate set at 10 to 90% and subsequently cooling and process.ing the cold rolled extrudate so as to manufacture a plate lattice, and a lead-acid battery comprising the particular lead (or a lead alloy) plate lattice.
L'invention concerne un procédé de production d'alvéole de plaque d'alliage de plomb ou de plomb pour une batterie d'accumulateur au plomb. Ce plomb se caractérise en ce qu'il consiste à extruder en continu du plomb ou un alliage de plomb à une température inférieure de 10 à 100·C au point de fusion de ce métal, puis à laminer l'extrudat jusqu'à obtenir un étirement de 10 à 90% à une température qui est inférieure de 50 à 230·C à celle du point de fusion du plomb ou d'un alliage de plomb. Ensuite, ce procédé consiste à soumettre le matériau laminé à un refroidissement et le façonner en une alvéole de plaque. Enfin, l'invention concerne une batterie d'accumulateur au plomb.
