Abstract

The invention relates to a lead-calcium alloy used on a starting type storage battery, which is composed of a lead-calcium-tin alloy. The lead-calcium-tin alloy comprises calcium, tin, aluminum, misch metal and lead; the weight percentage of the calcium in the lead-calcium-tin alloy is 0.02 to 0.06 percent; the weight percentage of the tin in the lead-calcium-tin alloy is 0.10 to 1.0 percent; the weight percentage of the aluminum in the lead-calcium-tin alloy is 0.01 to 0.03 percent; the weight percentage of the misch metal in the lead-calcium-tin alloy is 0.01 to 1.00 percent; the other weight percentage is composed of the lead. Compared with prior art, an electric vehicle battery which is assembled by a lead-acid accumulator grid produced by using the lead-calcium alloy has the advantages of corrosion resistance, deep cycle, large-current discharge and long service life.

Description

Technical field: [0001] The invention relates to the field of metallurgy, in particular to a lead-calcium alloy, in particular to a lead-calcium alloy for a start-up storage battery. Background technique: [0002] Low-calcium and high-tin alloys are widely used in lead-acid batteries. However, the price of the raw material tin has increased rapidly, which has increased the production cost of the alloy; in addition, in the lead-acid battery used for electric vehicles, the simple lead-calcium alloy has obvious early capacity loss, poor corrosion resistance of the battery, shallow cycle, and long service life. short. Invention content: [0003] The purpose of the present invention is to provide a lead-calcium alloy for starter batteries. The rare earth lead-calcium alloy will solve the early capacity loss of the battery caused by the lead-calcium alloy used in the lead-acid battery of electric vehicles in the prior art. , The technical problems of poor corrosion resistance,...
