Abstract: A bipolar electrode for a bipolar lead-acid battery includes a substrate (bipolar plate) in which a through hole for conduction is formed, a positive electrode bonded to one surface of the substrate with an adhesive layer, and a negative electrode bonded to another surface of the substrate with an adhesive layer.

Abstract: A lead alloy is described that is capable of manufacturing a positive electrode for a lead storage battery less likely to cause corrosion penetrating through a lead layer for the positive electrode in the thickness direction. The lead alloy contains 0.4% by mass or more and 2% by mass less of tin and 0.004% by mass or less of bismuth, with the balance being lead and inevitable impurities. When image analysis of a crystal orientation distribution map created by analyzing the surface of the lead alloy by an electron backscatter diffraction method is performed, intersection points of misorientation boundaries between crystal grains with a crystal misorientation of 5° or more and a straight line extending in one specific direction are extracted. The distances between two adjacent intersection points among the extracted intersection points are measured, and the average value of the distances is 50 ?m or less.
