Description

【発明の詳細な説明】 本発明は鉛蓄電池の製造法の改良に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved method for manufacturing lead-acid batteries.

従来の鉛蓄電池は過充電による電解液の減少に
より寿命に達するまでの間に数回以上の補水が必
要であり、特に寿命末期においては補水頻度が著
しく高くなる欠点があつた。 Conventional lead-acid batteries require water replenishment several times or more until the end of their lifespan due to a decrease in electrolyte due to overcharging, and they have had the disadvantage that the frequency of water replenishment becomes extremely high, especially at the end of their lifespan.

その液減りの原因となるのは主に陰極での水素
過電圧によるもので、水素過電圧が低いほど液減

と陽極格子からアンチモンが電解液中に溶出し陰
極に折出して水素過電圧を更に低下させるためで
あるとされている。 The main cause of liquid loss is hydrogen overvoltage at the cathode, and it is said that the lower the hydrogen overvoltage, the greater the liquid loss. In other words, the decrease in liquid is due to the fact that the hydrogen overvoltage at the cathode is reduced by 4 to 5% by weight of antimony added to the lattice alloy, and also because antimony is eluted from the anode lattice into the electrolyte and precipitated to the cathode, increasing the hydrogen overvoltage. It is said that this is to further reduce the

アンチモン−砒素−錫合金においてアンチモン含
有量を3.0重量％以下に抑えた通称低アンチモン
合金を格子材料として使用することが提案されて
いる。 Therefore, in order to reduce the frequency of water replenishment for lead-acid batteries, we use lead-calcium alloys or lead-calcium-tin alloys that do not contain any antimony in the lattice alloy, or lead-calcium-tin alloys that do not contain any antimony.
It has been proposed to use a so-called low antimony alloy, which is an antimony-arsenic-tin alloy with an antimony content of 3.0% by weight or less, as the lattice material.

ことは工業的に非常に好ましいことである。なぜ
ならば鉛資源の有効利用が計られるし、安価なた
めである。 By the way, this waste lead, commonly known as waste lead recovered and recycled from waste lead products, contains about 0.05% by weight of silver, about 0.05% by weight of bismuth, and about 0.05% by weight of copper as metals other than antimony, arsenic, and tin. It is industrially very desirable to use this as a basic material for lattice alloys. This is because lead resources can be used effectively and it is inexpensive.

くされている。 However, the waste lead is not used as the basic material for the lead-calcium alloy or lead-calcium-tin alloy lattice. This is because it is difficult to completely remove the metal components in the lead, and the trace amount of antimony that remains impairs castability. Therefore, it is necessary to use expensive refined lead (new lead) as the basic material of the lattice alloy.

18行目）。 Further, Japanese Patent Application Laid-Open No. 50-25427 proposes using dead lead as a basic material for a low-antimony alloy lattice. According to the examples in the publication, antimony 2.6% by weight, arsenic 0.3% by weight, tin 0.04% by weight, copper
A battery using an alloy having a composition of 0.02% by weight selenium, 0.09% by weight selenium, and the balance lead for the anode and cathode grids is
When overcharged, the alloy has a composition range of 5.8 to 6.4% by weight of antimony, 0.15 to 0.20% by weight of arsenic, 0.01 to 0.04% of copper, and 0.01 to 0.05% of tin with the balance being lead. Despite the decrease in antimony content, the cumulative water loss over 1000 hours actually increases due to the addition of selenium, and the water loss has not been effectively suppressed (see page 6 of the above publication). , Table 7 at the top of the left column). Incidentally, the waste lead proposed here does not substantially contain selenium. This is because selenium is a low boiling point metal and is scattered during the regeneration stage. Therefore, selenium was added to the waste lead later (page 2 of the above publication, line 6 at the bottom of the left column to line 6 at the bottom of the right column).

いることが余儀なくされている。 Furthermore, the present inventors have also investigated the above-mentioned antimony in which only the antimony content is 3.0% by weight or less,
It has been found that batteries using grids made from dead lead containing arsenic, tin, silver, bismuth, and copper cannot effectively reduce fluid loss. Therefore, even in the previously proposed grid using a so-called low antimony alloy to reduce the frequency of water replenishment for lead-acid batteries, new lead is used as the basic material of the grid alloy, and antimony, arsenic, and tin are added to it. It is necessary to use additive-prepared products.

電池の製造法を提供するものである。 The object of the present invention is to provide a lead-acid battery using a low antimony alloy lattice, in which waste lead is used as the basic material of the lattice alloy, and among the metal components contained therein, the content of metals that are involved in hydrogen overvoltage drop is reduced at the anode. By effectively utilizing waste lead, which is defined separately in the lattice alloy and the cathode lattice alloy, the present invention provides a method for producing a lead-acid battery that is inexpensive and has a stable liquid loss suppressing effect until the end of its life.

金の場合である。 As mentioned above, the loss of liquid in a lead-acid battery is affected by the hydrogen overvoltage at the cathode, but as a result of researching the degree of hydrogen overvoltage reduction for each metal contained in waste lead based on literature, it was found that antimony and copper had the greatest reduction. Therefore, we actually used a lead alloy plate to investigate the relationship between the content of antimony and copper in the lead alloy and the amount of drop from the hydrogen overvoltage of pure lead at a charging current of 0.3 A/cm 2 in 1 molar sulfuric acid at 40°C. The results are shown in Figure 1. A is for a lead-copper alloy, B is for a lead-antimony alloy, and C is for a lead-copper alloy containing 2.5% by weight of antimony.

た。 That is, like antimony, copper is a major factor in the reduction in hydrogen overvoltage, and when 2.5% by weight of antimony and copper coexist, additivity is observed in the reduction in hydrogen overvoltage. Additionally, experiments have shown that copper elutes from the anode grid into the electrolyte and is deposited on the cathode, thereby lowering the hydrogen overvoltage.

以上のことにより、故鉛を格子合金の基本材料

銅の含有量を考慮すればよいことがわかつた。 Based on the above, in order to reduce the loss of liquid in lead-acid batteries that use waste lead as the basic material for the lattice alloy, it is necessary to consider the contents of antimony and copper in the lattice alloy at both the negative and anode electrodes. I understood.

行なつた。 Therefore, we investigated the effect using single cells. To see the effect of antimony, 0.3% by weight of arsenic and tin
A lead alloy prepared using an alloy having a composition of 0.03% by weight and the balance of lead as a basic material so as to have an antimony content of 10% by weight or less was used. The antimony content was prepared by using the above basic material not containing antimony as a base alloy, and placing the alloy and a predetermined amount of metal antimony in a steel container and heating and melting them at about 400°C. For example, a composition having an antimony content of 2.5% by weight can be obtained by adding 25.6 g of antimony metal to 1 kg of the base alloy and heating and melting the mixture by the above method. In addition, in order to examine the effect of copper, we used a typical waste lead having a composition of 4.0% by weight of antimony, 0.3% by weight of arsenic, 0.03% by weight of tin, 0.05% by weight of copper, 0.05% by weight of silver, 0.05% by weight of bismuth, and the balance lead. As a basic material,
Antimony content 2.0-3.0% by weight, typically
The content of antimony and copper can be adjusted by using a lead alloy prepared to have a composition range of 2.5% by weight and a copper content of 0.1% by weight or less. This was carried out by heating and melting antimony metal, lead-copper (1:1% by weight) alloy prepared in advance in a steel container at about 400°C.

とによつて得られる。 For lead-copper (1:1% by weight) alloy, pure lead and metallic copper are placed in a carbon crucible and heated under an argon atmosphere.
Obtained by heating and dissolving at 1100°C. For example, one having a composition of 2.5% by weight of antimony and 0.06% by weight of copper can be obtained by adding 599.08g of pure lead and 0.92g of the above lead-copper alloy to 1 kg of the above-mentioned dead lead, and heating and melting the mixture.

てもよい。 Furthermore, for those with a composition of 2.5% by weight of antimony and 0.03% by weight of copper, 665.00g of pure lead per 1kg of dead lead mentioned above.
It is obtained by adding 1.67 g of antimony metal and heating and melting the mixture. Note that a lead-antimony alloy containing a high concentration of antimony may be prepared in advance and used instead of metallic antimony.

上記とは逆の構成のものを用いた。 Using the various lead alloys thus prepared, grids were cast according to conventional methods. A grid made of pure lead for the mating electrode was also made by casting according to the conventional method. When identifying the effect of the lattice alloy on the anode, the anode lattice was made from the lead alloy prepared above, and the cathode lattice was made from pure lead. When identifying the effect at the cathode, a configuration opposite to the above was used.

Using this test battery with grids made from various lead alloys, we measured the amount of hydrogen overvoltage drop a at an initial charging current of 0.3 A/cm 2 and the charging current of 0.3 A after 700 hours of continuous overcharging at a constant voltage of 2.47 V at 50°C. Hydrogen overvoltage drop amount b at / cm2
The amount of liquid loss c after 700 hours was investigated. In order to distinguish the effects of the cathode and anode lattice alloys, Figure 2 shows the effect of the cathode lattice alloy using pure lead for the anode lattice, and Figure 3 shows the effect of the cathode lattice alloy using pure lead for the cathode lattice. This shows the effect of the alloy.

れている。 That is, as shown in Figure 2, the antimony content in the lead-antimony alloy lattice of the cathode is 3.0% by weight.
Up to 3.0% by weight, the hydrogen overvoltage gradually decreases, and remains almost unchanged above 3.0% by weight. In fact, when the antimony content is less than 2.0% by weight, castability is significantly impaired. On the other hand, when the copper content in the lead-copper alloy lattice containing 2.5% by weight of antimony reaches 0.06% by weight, the hydrogen overvoltage gradually decreases, but when it exceeds 0.06% by weight, there is almost no change. In addition, the amount of decrease in hydrogen overvoltage between the initial period a and after 700 hours b is as follows: when the antimony content in the lead-antimony alloy lattice is 3.0% by weight or less, and when the copper content in the lead-copper alloy lattice containing 2.5% antimony. When it is 0.06% by weight or less, it is stable with almost no difference between the initial stage a and 700 hours later b, which is also reflected in the small amount of liquid loss c.

かる。 Regarding the anode lattice alloy, as shown in Figure 3, the initial a shows the same tendency as in Figure 2, but 700
After time b, the antimony content in the lead-antimony alloy lattice is 3.0% by weight or more and 2.5% by weight.
It can be seen that when the copper content in the antimony-containing lead-copper alloy lattice is 0.03% by weight or more, the hydrogen overvoltage decreases rapidly and the amount of liquid loss also increases.

ことによつて簡単に得られる。 From the above, as the cathode lattice alloy, we used a lead alloy made from the above-described deceased lead as a basic material and prepared the antimony content to a small amount of 2.0 to 3.0% by weight and the copper content to a small amount of 0.06% by weight or less, and as the anode lattice alloy, The antimony content is 2.0 using the above deceased lead as the basic material.
By effectively utilizing waste lead by using a lead alloy with a small amount of ~3.0% by weight and a copper content of 0.03% by weight or less, the drop in hydrogen overvoltage is small even during long-term overcharging. Since there is no rapid increase in the amount of liquid lost during heating, it is possible to obtain a lead-acid battery at a low cost that does not require frequent rehydration at the end of its life. It can be easily obtained by preparing only the copper content.
