Publication number: 20230178712Abstract: A lead alloy is described that is capable of manufacturing a positive electrode for a lead storage battery with a reduced likelihood of causing growth. The lead alloy contains 0.4% by mass or more and 2% by mass or less of tin and 0.004% by mass or less of bismuth, with the balance being lead and inevitable impurities. The diffraction intensity of a Cube orientation {001} <100> in a pole figure created by analyzing the surface of the lead alloy by an X-ray diffraction method is 4 times or less the diffraction intensity of a random orientation in a pole figure created by analyzing a pure lead powder by the X-ray diffraction method.Type: ApplicationFiled: January 31, 2023Publication date: June 8, 2023Inventors: Hiroshi Kaneko, Yoshiaki Ogiwara, Miho Yamauchi, Akira Tanaka, Hideto Nakamura, Masanobu Aragaki, Jun Furukawa, Toru Mangahara, Keizo Yamada, Ayano Koide, Atsushi Sato

Publication number: 20230170464Abstract: 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.Type: ApplicationFiled: January 31, 2023Publication date: June 1, 2023Inventors: Hiroshi Kaneko, Yoshiaki Ogiwara, Miho Yamauchi, Akira Tanaka, Hideto Nakamura, Masanobu Aragaki, Jun Furukawa, Toru Mangahara, Keizo Yamada, Ayano Koide, Atsushi Sato
