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:
The present invention relates to field of metallurgy, relate in particular to lead-calcium alloy, particularly a kind of plumbum calcium alloy for starting type accumulators.
Background technology:
Low calcium high tinalloy is widely used in lead acid cell.But wherein the price of starting material tin rapidly increases, and has increased the production cost of alloy; In addition, simple lead-calcium alloy is being used for the lead acid cell of power truck, and early stage capacitance loss is obvious, store battery poor corrosion resistance, shallow, the life-span weak point of circulation.
Summary of the invention:
The object of the present invention is to provide a kind of plumbum calcium alloy for starting type accumulators, described this rare earth lead-calcium alloy will solve the early stage capacitance loss of the store battery that lead-calcium alloy caused that is used for lead-acid battery of electric vehicle in the prior art, battery poor corrosion resistance, circulation is shallow, the life-span is short technical problem.
This rare earth lead-calcium alloy of the present invention is made up of lead-calcium-tin alloy, wherein, contain calcium, tin, aluminium, mishmetal and lead in the described lead-calcium-tin alloy, the weight percent of calcium in described lead-calcium-tin alloy is 0.02%～0.06%, the weight percent of tin in described lead-calcium-tin alloy is 0.10%～1.0%, the weight percent of aluminium in described lead-calcium-tin alloy is 0.01%～0.03%, the weight percent of mishmetal in described lead-calcium-tin alloy is 0.01%～1.00%, and surplus is plumbous.
Further, described mishmetal is any one element in lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd) rare earth element, or the mixture of any two or more element in the above-mentioned rare earth element.
Further, contain selenium in the described lead-calcium-tin alloy, the weight percent of selenium in described lead-calcium-tin alloy is 0.01～0.05%.
Further, contain arsenic in the described lead-calcium-tin alloy, the weight percent of arsenic in described lead-calcium-tin alloy is 0.01～0.20%.
