Description

本発明は、制御弁式鉛蓄電池の正極板及び負極板に用いるための集電体に関するものである。   The present invention relates to a current collector for use in a positive electrode plate and a negative electrode plate of a control valve type lead-acid battery.

制御弁式鉛蓄電池は安価で信頼性が高いという特徴を有するために、無停電電源装置や電力貯蔵用に使用されている。最近、制御弁式鉛蓄電池の長寿命化が強く要求されている。   Control valve-type lead-acid batteries are used for uninterruptible power supplies and power storage because they have the feature of being inexpensive and highly reliable. Recently, there is a strong demand for extending the life of control valve-type lead-acid batteries.

これらの制御弁式鉛蓄電池は、一般的にペースト式正極板及びペースト式負極板を、ガラス繊維製のセパレータを介して積層し、溶接して極板群を作製し、該極板群を電槽に挿入して作成するものである。そして、制御弁式鉛蓄電池は、ペースト式正極板、ペースト式負極板及びセパレータに、電解液として希硫酸を染み込ませた状態で使用している。   These control valve-type lead-acid batteries are generally made by laminating a paste-type positive electrode plate and a paste-type negative electrode plate via a glass fiber separator and welding them to produce an electrode plate group. It is created by inserting it into a tank. And the control valve type lead acid battery is used in the state which made the paste type positive electrode plate, the paste type negative electrode plate, and the separator impregnate dilute sulfuric acid as an electrolyte solution.

これらの制御弁式鉛蓄電池の正極板及び負極板は、鉛合金からなる格子状の正極用集電体1と負極用集電体2にペースト状活物質を充填し、保持させた構造のペースト式電極板である。そして、従来は正極用集電体1と負極用集電体2の格子の縦骨4及び横骨5は、概ね対峙するように積層されている（図４）。すなわち、正極用集電体1と負極用集電体2に活物質を保持させた構造のペースト式電極板がセパレータ7を介して積層・溶接されて極板群が構成されている。   The positive electrode plate and the negative electrode plate of these control valve type lead storage batteries are pastes having a structure in which a paste-like active material is filled and held in a grid-like positive electrode current collector 1 and negative electrode current collector 2 made of a lead alloy. Type electrode plate. Conventionally, the vertical bones 4 and the horizontal bones 5 of the grid of the positive electrode current collector 1 and the negative electrode current collector 2 are laminated so as to face each other (FIG. 4). That is, a paste type electrode plate having a structure in which an active material is held in the positive electrode current collector 1 and the negative electrode current collector 2 is laminated and welded via the separator 7 to constitute an electrode plate group.

ここで、正極用集電体1と負極用集電体2の枠骨3が、対峙した状態で積層をすると、セパレータ7を切断してしまう場合が知られている。そこで、正極用集電体1と負極用集電体2の枠骨3が対峙しないように積層する方法が提案されている（例えば、特許文献１参照。）。   Here, when the frame 3 of the positive electrode current collector 1 and the negative electrode current collector 2 are laminated in a state of facing each other, it is known that the separator 7 is cut. Therefore, a method of laminating the positive electrode current collector 1 and the negative electrode current collector 2 so as not to face each other is proposed (see, for example, Patent Document 1).

A cycle life test was performed in which 102% of the discharge amount was charged at a constant voltage of 45 V / cell. And the accumulation amount of the lead sulfate of a negative electrode plate was measured after 1000 cycles progress. Moreover, the voltage at the time of discharge was measured every 100 cycles, and the time when 1.7 V / cell was cut within 4 hours was defined as the life.

Here, the positive electrode current collector 1 and the negative electrode current collector 2 had the same area, and the positive electrode current collector 1 was thicker than the negative electrode current collector 2. Then, after filling each paste-like active material, the frame bone 3, the vertical bone 4 and the horizontal bone 5 were laminated so as to overlap each other to form an electrode plate group (FIG. 4B).

なお、それぞれの活物質の量は正極板の活物質質量が１に対して、負極板の活物質質量は０．７５と少なくした。また、負極活物質中には、一般的に添加されているリグニン、硫酸バリウムの他に、導電剤としてカーボン粉末を活物質質量に対して、０．２％添加した。その他の制御弁式鉛蓄電池の作製方法及び試験方法は、上記したとうりである。

ここで、正極用集電体1及び負極用集電体2の面積は同じとし、厚みは正極用集電体1が負極用集電体2よりも厚くした。   Here, the positive electrode current collector 1 and the negative electrode current collector 2 had the same area, and the positive electrode current collector 1 was thicker than the negative electrode current collector 2.

そして、（図２（ｂ））に示すように、それぞれペースト状活物質を充填した後に、枠骨3と横骨5のみがそれぞれ重なり合うように積層して極板群とした。すなわち、正極用集電体1と負極用集電体2の縦骨4が対峙しない状態で積層した。   Then, as shown in FIG. 2 (b), after filling each with a paste-like active material, only the frame bone 3 and the transverse bone 5 were laminated so as to overlap each other to form an electrode plate group. That is, the positive electrode current collector 1 and the negative electrode current collector 2 were laminated so that the vertical bones 4 did not face each other.

なお、それぞれの活物質の量は正極板の活物質質量が１に対して、負極板の活物質質量は０．７５と少なくした。また、負極活物質中には、一般的に添加されているリグニン、硫酸バリウムの他に、導電剤としてカーボン粉末を活物質質量に対して、０．２％添加した。その他の制御弁式鉛蓄電池の作製方法及び試験方法は、上記したとうりである。
（実施例３）
実施例３の制御弁式鉛蓄電池として、正極用集電体1は、周囲の枠骨3とその内側に縦骨4及び横骨5がそれぞれ８本からなり、負極用集電体2は、周囲の枠骨3とその内側に縦骨4と横骨5がそれぞれ９本からなる格子状の集電体を用いた（図１（ａ））。 In addition, the amount of each active material was as small as 0.75 with respect to the active material mass of a positive electrode plate with respect to 1 with respect to the active material mass of a negative electrode plate. In addition to the commonly added lignin and barium sulfate, 0.2% of carbon powder as a conductive agent was added to the negative electrode active material with respect to the active material mass. The other production methods and test methods of the control valve type lead storage battery are as described above.
(Example 3)
As the control valve type lead storage battery of Example 3, the current collector 1 for the positive electrode is composed of the surrounding frame bone 3 and the longitudinal bone 4 and the horizontal bone 5 inside thereof, and the current collector 2 for negative electrode is A grid-like current collector consisting of the surrounding frame bone 3 and nine longitudinal bones 4 and transverse bones 5 inside each was used (FIG. 1A).

ここで、正極用集電体1及び負極用集電体2の面積は同じとし、厚みは正極用集電体1が負極用集電体2よりも厚くした。   Here, the positive electrode current collector 1 and the negative electrode current collector 2 had the same area, and the positive electrode current collector 1 was thicker than the negative electrode current collector 2.

そして、（図１（ｂ））に示すように、それぞれペースト状活物質を充填した後に、枠骨3のみがそれぞれ重なり合うように積層して極板群とした。すなわち、正極用集電体1と負極用集電体2の縦骨4と横骨5が対峙しない状態で積層した。   Then, as shown in FIG. 1 (b), after filling each with a paste-like active material, only the frame bones 3 were laminated so as to overlap each other to form an electrode plate group. In other words, the positive electrode current collector 1 and the negative electrode current collector 2 were laminated so that the longitudinal bones 4 and the transverse bones 5 did not face each other.

なお、それぞれの活物質の量は正極板の活物質質量が１に対して、負極板の活物質質量は０．７５と少なくした。また、負極活物質中には、一般的に添加されているリグニン、硫酸バリウムの他に、導電剤としてカーボン粉末を活物質質量に対して、０．２％添加した。その他の制御弁式鉛蓄電池の作製方法及び試験方法は、上記したとうりである。
（実施例４）
実施例４として、導電剤としてカーボン粉末を負極板の活物質質量に対して、１．０％添加した。その他の制御弁式鉛蓄電池の作製方法及び試験方法は、実施例３と同一である。 In addition, the amount of each active material was as small as 0.75 with respect to the active material mass of a positive electrode plate with respect to 1 with respect to the active material mass of a negative electrode plate. In addition to the commonly added lignin and barium sulfate, 0.2% of carbon powder as a conductive agent was added to the negative electrode active material with respect to the active material mass. The other production methods and test methods of the control valve type lead storage battery are as described above.
Example 4
As Example 4, 1.0% of carbon powder was added as a conductive agent with respect to the active material mass of the negative electrode plate. The other production methods and test methods for the valve-regulated lead-acid battery are the same as those in Example 3.

１０００サイクル経過後に負極板の硫酸鉛の蓄積量と、寿命サイクルを測定した結果を表１に示す。表１に示しように、比較例１の電池は負極板の硫酸鉛量が３５％に対し、本発明による電池では、実施例１で２４％、実施例２で２１％、実施例３で２０％と硫酸鉛の蓄積量が少なくなった。すなわち、本発明を用いると充電性能が向上していることがわかる。   Table 1 shows the results of measuring the amount of lead sulfate accumulated in the negative electrode plate and the life cycle after 1000 cycles. As shown in Table 1, the battery of Comparative Example 1 has a negative electrode plate having a lead sulfate content of 35%, while the battery according to the present invention has 24% in Example 1, 21% in Example 2, and 20 in Example 3. % And lead sulfate accumulation decreased. That is, it can be seen that the charging performance is improved by using the present invention.

また、負極活物質に導電剤として添加したカ−ボン粉末の量が１．０％と多い比較例２では１８％、実施例４では１２％とカーボン添加量が多くすることにより充電性能を向上させた場合でも、本発明の効果が認められた。なお、電池の寿命性能も向上しており、寿命時点の電池に調査より、負極板中の硫酸鉛の蓄積による容量低下であることが確認できた。   In addition, the charge performance is improved by increasing the amount of carbon added to the negative electrode active material as a conductive agent, ie, 18% in Comparative Example 2 with a large amount of 1.0% and 12% in Example 4. The effect of the present invention was recognized even when it was made to do. In addition, the life performance of the battery was improved, and it was confirmed from the investigation of the battery at the end of the life that the capacity was reduced due to accumulation of lead sulfate in the negative electrode plate.

なお、本実施例では、正極板に対して、負極板の縦骨又は横骨の数を増やす形で実施をしたが、その逆の場合でもほぼ同様の効果が認められた。また、本発明は集電体の骨の向きに関わりなく効果があるほか、斜めに設けた骨の場合や、あるいは部分的に骨の本数を増やした場合にも同様の効果が認められた。   In this example, the number of longitudinal bones or transverse bones of the negative electrode plate was increased with respect to the positive electrode plate, but substantially the same effect was observed in the opposite case. In addition, the present invention is effective regardless of the direction of the bone of the current collector, and the same effect was observed in the case of a bone provided obliquely or when the number of bones was partially increased.

本発明を用いると、負極活物質が充電されやすく、長寿命な制御弁式鉛蓄電池を提供することができる。   By using the present invention, it is possible to provide a control valve type lead-acid battery in which the negative electrode active material is easily charged and has a long life.
