A lead-acid battery grid made from a lead-based alloy containing, in addition to lead, tin at a concentration that is at least about 0.500%, silver at a concentration that is greater than 0.006%, and bismuth at a concentration that is at least about 0.005%, and, if calcium is present in the lead-based alloy, the calcium is at concentration that is no greater that about 0.010%.
L'invention concerne une grille d'accumulateur au plomb acide fabriquée à partir d'un alliage à base de plomb contenant, outre le plomb, de l'étain à une concentration qui est d'au moins environ 0,500 %, de l'argent à une concentration qui est supérieure à 0,006 %, et du bismuth à une concentration qui est d'au moins environ 0,005 %. Si du calcium est présent dans l'alliage à base de plomb, la concentration du calcium n'est pas supérieure à environ 0,010 %.
