Abstract: 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.

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.

Abstract: A method of producing an electrode plate used for a lithium secondary battery and a lithium secondary battery containing such an electrode plate. The electrode plate is produced by coating a coating slurry of an active material mixture agent added with oxalic acid on a collector, drying and pressing, so as to obtain an electrode plate improved in charge-discharge cycle characteristics when used in a lithium secondary battery.

Abstract: An electrode for a rechargeable battery with a nonaqueous electrolyte is provided wherein the active material layer has a sufficient flexibility, the adhesion between the active material coating and the metal foil collector is good, none of peeling, falling, cracking and other unfavorable phenomena occur in the active material coating in the step of assembling a battery and excellent discharge characteristics can be developed. The electrode for a rechargeable battery with a nonaqueous electrolyte comprises a metal foil collector and, formed on at least a part of the metal foil collector, an active material layer comprising an active material and a cured reaction-curing binder as essential components.
