Seven types were prepared with a t of 40.50 μm. The copper substrate was immersed in a molten 99.99% pure vessel for 5 seconds,
Furthermore, five types of current collectors each having a lead layer formed by electroplating with a thickness of Or5,10*15+20#' were prepared.
これらの集を体に負極活物質を充填した極板５枚と鉛合
金を集電体とした正極板６枚とで鉛蓄電池を製作した。A lead-acid battery was fabricated from these batteries by using five electrode plates filled with a negative electrode active material and six positive electrode plates using a lead alloy as a current collector.

の有無を示した表である。After discharging this battery to a final voltage of 1.70 V at a current rate of 10 hours, the positive and negative terminals were short-circuited and left for one week. Table 1 shows the results of analyzing the battery electrolyte after being left standing to check for copper elution. This is a table showing the thickness of electroplating and the presence or absence of copper elution.

A 10 μm lead layer was formed by electroplating. Anode current was applied to these current collectors, and the elution time of copper was measured.

By hot-dip plating on an alloy steel substrate, a negative electrode current collector in which copper is difficult to be eluted even if the lead coating is 10 μm thick by one electroplating can be obtained.

の性能が得られた。This is thought to be because the Pb-Sb alloy has better adhesion to the steel substrate than pure lead. There is no major harm to Pb-Sb alloy and lead-acid batteries, but they have the disadvantage of increasing the amount of self-discharge.However, since lead is further electroplated on the Pb-Sb alloy, Pb-Sb alloy current collectors and lead-acid batteries The amount of self-discharge will be smaller than that. Similarly to Example 2, in the Pb-Sn alloy, if Sn was 3% or more, performance equivalent to or higher than that of 3.5% Sb was obtained.

められた。Similar effects were also observed in the Pb-Sn-Sb alloy layer.

という問題が生じる。- Generally, the ears are provided by casting, but if the ears are provided before hot-dip lead plating, the ears will melt during the hot-dip lead plating. Furthermore, if ears are provided by casting after air plating, the problem arises that the lead plating near the ears melts, exposing the copper, or that the plating thickness becomes thinner.

This is fitted into a casting frame for forming ears, and a Pb-sb molten alloy having the same < sb% of 3.5% is poured into the mold, and after cooling, it is taken out. A 10 μm lead layer was formed by electroplating to obtain a negative electrode current collector. Using the obtained negative electrode current collector, a lead-acid battery similar to that in Example 1 was produced and tested, and as a result, the same effects as in Example 1 were observed.
