る。However, when calcium (Ca) is added to the lead-tin (Pb-Sn) -based alloy in an amount of more than 0.02% by weight, the molten metal itself is easily oxidized and an oxide layer is easily formed on the surface thereof. As a result, when the battery component is formed, the strap, the inter-cell connection body and the poles are easily oxidized, and the oxidation progresses, which also causes breakage. Therefore, lead-tin (Pb) in which the content of antimony (Sb) is reduced by adding calcium (Ca) in the range of 0.005 to 0.02% by weight.
By using the —Sn) -based alloy, it is possible to obtain a battery component such as a strap, an inter-cell connection body and a pole that has excellent corrosion resistance, and it is possible to improve the corrosion resistance of the lead storage battery.
