本発明は、鉛蓄電池の改良に関するものでちゃ、初期緩

期容量劣化を抑制することを目的とする。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvement of lead-acid batteries, and aims to maintain initial slow discharge capacity and improve cycle life. In particular, the purpose is to suppress early capacity deterioration in patterns including deep discharge cycles that occur when a lead-calcium alloy is used for the grid.
ペースト式鉛蓄電池は、利用率が高く、しかも製法が比
較的簡単であるという特徴を持っている。Paste type lead-acid batteries are characterized by high utilization rates and relatively simple manufacturing methods.
このペースト式電池の中で、鉛−カルシウム系合金を格

傾向にある。格子合金に鉛−アンチモン系を用いると、
この短所はある程度解決される。しかし近年、鉛蓄電池

折りから、鉛−カルシウム系格子合金でこの問題を解決
しておくことが工業上重要である。Among these paste type batteries, those using a lead-calcium alloy for the lattice tend to suffer from the above-mentioned early capacity deterioration. When a lead-antimony system is used as a lattice alloy,
This shortcoming is resolved to some extent. However, in recent years, there has been a strong demand for maintenance-free lead-acid batteries, so it is industrially important to solve this problem with a lead-calcium lattice alloy.

記の劣化現象が起こりやすい。これを改善するために、
鉛−カルシウム格子合金組成あるいは添加剤などの検討
がなされているが、まだ十分な効果は得られていない。When using alloys that do not contain or contain very little antimony, such as lead-calcium alloys, easily exfoliated oxides are formed on the lattice surface, creating cracks and faults, and sulfuric acid can enter the cracks. It is said that early deterioration occurs due to the formation of an insulating layer at the interface between the lattice and the active material. Furthermore, lead-calcium alloys tend to use expanded metal or smooth plate processed bodies such as perforated plates to compensate for poor castability; The above deterioration phenomenon is even more likely to occur. To improve this,
Investigations have been made into lead-calcium lattice alloy composition and additives, but sufficient effects have not yet been obtained.
そこで本発明は、上記の早期劣化を抑制する課題に対し
て、基本的には、格子（集電体）の表面にアルカリ水溶
液の液膜を形成する工程と、上記処理の後にペーストを
充填する工程を有することを特徴と子る鉛蓄電池用電極
の製造法を提供するものである。Therefore, in order to solve the problem of suppressing the early deterioration mentioned above, the present invention basically consists of a step of forming a liquid film of an alkaline aqueous solution on the surface of the grid (current collector), and filling the paste with a paste after the above treatment. The present invention provides a method for manufacturing an electrode for a lead-acid battery, which comprises a process.
この液膜の形成には、例えば格子をアルカリ水溶液中に
含浸し引き上げたり、空間中で噴霧するなど一般に濡ら
すという方法が適用できる。To form this liquid film, a general method of wetting the grid, such as, for example, impregnating the grid in an aqueous alkaline solution and pulling it up, or spraying it in space, can be applied.
上記の手段が早期容量劣化の抑制に有効である理由につ
いては、つぎのように考えられる。The reason why the above-mentioned means are effective in suppressing early capacity deterioration is considered as follows.
壕ず、早期容量劣化の、現象は、先にのべたように、格
子と活物質の界面の挙動とほぼ断定できる。As mentioned earlier, the phenomenon of no trenching and early capacity deterioration can almost be determined to be caused by the behavior of the interface between the lattice and the active material.
本発明の適用により、格子表面にアルカリ水溶液の液膜
が形成され、ここにペーストが充填されると、鉛の酸化
物、主に塩基性硫酸鉛がＰｂ（ＯＨ）３− 。By applying the present invention, a liquid film of aqueous alkaline solution is formed on the lattice surface, and when the paste is filled therein, lead oxides, mainly basic lead sulfate, are formed as Pb(OH)3-.
Ｐｂ（ＯＨ）４’−などの形で溶解するものと思われる
。It is thought that it is dissolved in the form of Pb(OH)4'- or the like.
この液膜が乾燥してゆく過程でアルカリ濃度は上昇し、
上記の溶解物は、液膜中に増加する。さらに乾燥してい

の状態から硫酸中で化成充電すると、本発明を適用しな
いで乾燥した格子に直接ペーストを充填した場合とは異
なる緻密で結着力の優れた酸化物が生成し、界面を保護
するものと推察される。As this liquid film dries, the alkali concentration increases,
The above dissolved substances build up in the liquid film. As it dries further, these zinc acid compounds precipitate near the interface. It is presumed that when this state is chemically charged in sulfuric acid, a dense oxide with excellent binding strength is generated, which is different from when the paste is directly filled into a dry lattice without applying the present invention, and protects the interface. Ru.
上記のことから基本的には、アルカリ水溶液の液膜が未
乾燥（未だ湿潤している状態）でペーストを充填する方
が好ましく、そのことは後の実施例でも述べるように、
液膜を形成してからペーストを、充填する間に放置する
時間の影響の形で効果が変化する。しかし、完全に乾燥
した後にペーストを塗着しても効果がある場合がある。From the above, it is basically preferable to fill the paste while the liquid film of the alkaline aqueous solution is undried (still wet), and this will be explained in the examples below.
The effect changes as a function of the time the paste is allowed to stand between filling after forming the liquid film. However, it may be effective to apply the paste after it is completely dry.
それは、１
あらかじめ格子の表面を一部または全部酸化させた場合
にとくに起こりやすべ。それは液膜形成後から乾燥まで

層の中に存在させることになるからである。しだがって
、例えば、酸化雰囲気中で格子を長時間曝すとか、湿度
や温度を上昇するなど、一般的に酸化する方法を適用し
てあらかじめ表面に酸化物を形成しておくと良い。This is especially likely to occur if the surface of the lattice is partially or completely oxidized in advance. In the process from the formation of the liquid film to its drying, sufficient lead compounds to modify the interface are present in the liquid film or its dried layer without the aid of oxides on the paste side. Because it will be. Therefore, it is preferable to form an oxide on the surface in advance by applying a general oxidizing method, such as exposing the grid in an oxidizing atmosphere for a long time or increasing humidity or temperature.
さらに、このあらかじめ格子側の表面を酸化する方法と

てんする方法とを併合すると、相互から酸化物が溶出し

的には、優れた界面の改質効果を示し、早期容量劣化の
抑制は強いものとなる。Furthermore, if we combine this method of oxidizing the surface on the lattice side in advance with the method of filling the paste at a point where the alkaline aqueous solution has not dried, oxides will be eluted from each other, and a precipitated layer will be formed in close contact with each solid. As a result, an excellent interface modification effect is obtained, and early capacity deterioration is strongly suppressed.
以下、実施例によって、本発明の構成と効果を述べる。Hereinafter, the configuration and effects of the present invention will be described with reference to Examples.

順序に従いＡ。After being immersed in a 0.5 mol/λ, 1 D mol/2 sodium hydroxide aqueous solution for 1 minute, the grid was taken out from the alkaline aqueous solution and immediately filled with lead paste. Thereafter, the paste was dried, aged, and chemically charged as a positive electrode to form a battery with one positive electrode plate and two negative electrode plates. A conventional negative electrode plate was used. A each of these batteries according to the above order.

水酸化ナトリウムの濃度が高い方が特性が良いことがわ
かる。Six batteries thus prepared were subjected to a cycle test at a 3 hour rate discharge. Figure 1 shows the cycle characteristics. As is clear from the figure, cycle life characteristics are improved by immersing the grid in an alkaline aqueous solution to form an alkaline liquid film and then filling it with paste. Also,
It can be seen that the higher the concentration of sodium hydroxide, the better the characteristics.
第２図は、初期容量の６０％になるまでのサイクル数で

である。この図から、水酸化ナトリウムの濃度は０．１

μ以上にしても０．５モル／２程度と効果は基本的に変
わらない。FIG. 2 shows the relationship between the lifetime, expressed as the number of cycles until 60% of the initial capacity, and the concentration of sodium hydroxide. However, the immersion time of the grid in the alkali was 1 minute in all cases. From this figure, the concentration of sodium hydroxide is 0.1
It is effective even at concentrations as low as 1 mol/β, and
Even if the amount is more than μ, the effect remains basically the same at about 0.5 mol/2.
また、サイクル寿命特性は、アルカリ水溶液中での浸漬
時間にあまり依存しなかった。すなわち浸漬時間を長く
しても、格子表面に付着している水酸化ナトリウム水溶
液の量は変化しないと考えられる。Moreover, the cycle life characteristics did not depend much on the immersion time in the alkaline aqueous solution. In other words, it is considered that even if the immersion time is increased, the amount of the sodium hydroxide aqueous solution adhering to the grid surface does not change.
次に、サイクル寿命特性と、格子をアルカリ水溶液中か

る。Next, we investigated the relationship between cycle life characteristics and the time from when the grid was taken out of the aqueous alkaline solution until it was filled with paste. The results are shown in FIG. At this time, the grid was immersed in a 0.5 mol/2 alkaline aqueous solution for 1 minute. From this figure, it can be seen that as the time until filling with paste increases, the number of life cycles decreases. This seems to be because the longer the standing time, the dryer the liquid film of the aqueous alkaline solution becomes, the liquid film becomes thinner, and the absolute amount of dissolved substances such as zincate ions decreases.

した電極Ｓのサイクル寿命特性も調べた。Next, the lattice whose surface had been oxidized by leaving it in an oxidizing atmosphere at a humidity of 80% and a temperature of 70°C for 2 hours was immersed for 1 minute in an alkaline aqueous solution of 0.5 mol/2, and then the paste was immediately applied. The cycle life characteristics of the filled electrode P and the electrode Q filled with paste after being left in air for 2 hours were investigated. For comparison, the grid without the above oxidation treatment was similarly immersed in a 0.5 mol/2 alkaline aqueous solution for 1 minute, and then immediately left in the air with electrode R filled with paste for 2 hours. The cycle life characteristics of the electrode S filled with the paste were also investigated.

れても、アルカリ水溶液の液膜が乾燥し、液膜が薄くな

期容量劣化の抑制効果は著しく低下することが認められ
た。FIG. 4 shows the number of life cycles of these four electrodes. From this figure, the electrode P using the lattice whose surface is oxidized is R
It can be seen that even Q, which is filled after drying, has better life characteristics than S. In other words, when the surface is oxidized and a liquid film of alkaline aqueous solution is formed on the lattice, lead oxide
Since it is dissolved in the form of zincate ions and attached to the surface,
Even if the liquid film of the alkaline aqueous solution is dried by being left in the air for 2 hours, a dense precipitated layer still exists at the interface, which is highly effective in suppressing early capacity deterioration. However, in the case of a lattice whose surface is not oxidized, even if a liquid film of alkaline aqueous solution is formed on the lattice surface, when the liquid film of alkaline aqueous solution dries and becomes thin, dissolved substances such as zincate ions can be removed. It was observed that the absolute amount decreased and the effect of suppressing early capacity deterioration was significantly reduced.
また、鉛の酸化物や塩基性硫酸鉛は、中性や酸性水溶液
にほとんど溶解しないので、格子表面上に中性や酸性の
水溶液のフィルムを形成しても必ずしもうまく効果を得
にくい。In addition, lead oxides and basic lead sulfate hardly dissolve in neutral or acidic aqueous solutions, so forming a film of neutral or acidic aqueous solutions on the lattice surface does not necessarily produce a good effect.
なお、本発明ではアルカリ水溶液の液膜中への鉛酸化物

れた。The present invention takes advantage of the solubility of lead oxide in the liquid film of an aqueous alkali solution, and even if an aqueous solution of sodium hydroxide is used as the aqueous alkali solution, other alkalis such as potassium hydroxide cannot be used. A similar effect was observed when using
以上のよ２に、本発明は格子と活物質の界面の性質を改
善し、効果的に電池寿命を改善するものである。As described above, the present invention improves the properties of the interface between the lattice and the active material, thereby effectively improving the battery life.
