Battery industry

Product Introduction:

In the past years, using calcium in casting and making lead parts has increased the strength of this alloy. In many cases, lead-calcium alloys have replaced lead-antimony alloys, especially in manufacturing battery plates. The amount of calcium in these alloys is 0.03-0.15 weight percent, and recently aluminum has been added to these alloys as a calcium stabilizer. Alloys recently used to make battery plates under the name of calcium batteries usually have the following elements: calcium 0.05-0.12 weight percent, tin at most three weight percent, aluminum 0.002-0.04 weight percent, and less than 0.02 weight percent barium.

Due to the removal of elements such as antimony and arsenic in these alloys, the toxic compounds resulting from the reaction of hydrogen with these elements have been removed, and the possibility of sealing the battery has been provided. Anode plates in zinc electrowinning and all types of batteries with lead sheets are the primary consumers of this alloy. To use this alloy, a percentage of calcium should be replaced with aluminum to prevent the reaction of calcium with air by forming a protective film on the surface of the molten lead.
