NEGATIVE ELECTRODE CURRENT COLLECTOR FOR LEAD STORAGE BATTERY AND LEAD STORAGE BATTERY INCLUDING THE SAME

摘要

A negative electrode current collector for a lead-acid battery having a grid part, upper frame part, and lug part according to the present invention, where the upper frame part and lug part have a surface layer, a surface layer is an alloy of Pb and Sn and the mass ratio of Sn accounts for 10% or more in the whole alloy, an alloy of Pb and Sb and the mass ratio of Sb accounts for 10% or more in the whole alloy, an alloy of Pb, Sn and Sb and the total mass ratio of Sn and Sb accounts for 10% or more in the whole alloy, Sn, or Sb. Further, a negative electrode current collector for a lead-acid battery having a grid part, upper frame part, and lug part according to the present invention, only upper frame part and lug part have a surface layer.
