産業上の利用分野
本発明は、電解液が少なく制限され、遊離したフリーな
電解液のない密閉形鉛蓄電池の電槽内化成方法に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for forming a sealed lead-acid battery in a cell, in which the amount of electrolyte is limited and there is no free electrolyte.
従来の技術
密閉形鉛蓄電池は、充電時に正極より発生する酸素ガス
を負極に吸収させることで電解液の減少を防いでいる。Conventional sealed lead-acid batteries prevent the electrolyte from depleting by having the negative electrode absorb oxygen gas generated from the positive electrode during charging.
そこで負極は酸素を吸収できる様に、気層（酸素）およ
び液層（電解液）が同時に接触しなければならない。こ
の状態では負極は充電と同時に放電しているため、未化
成極板を化成することはできない。そのため、一般に密
閉形鉛蓄電池は正極活物質を二酸化鉛に、負極活物質を
鉛にそれぞれ変化させる化成工程を電池組立以前に電槽
外で行なっている。Therefore, the gas layer (oxygen) and the liquid layer (electrolyte) must be in contact at the same time so that the negative electrode can absorb oxygen. In this state, the negative electrode is being charged and discharged at the same time, so that the unformed electrode plate cannot be chemically formed. Therefore, in sealed lead-acid batteries, a chemical conversion process is generally performed to change the positive electrode active material to lead dioxide and the negative electrode active material to lead, respectively, outside the battery case before the battery is assembled.
しかし、電槽外で化成をすることは、負極活物質の酸化
劣化を防止する即用乾燥処理をともなうこと、さらに電
池組立後に活性化のための充電を必要とするなど電池製
造工程が煩雑となり、コスト高となっていた。However, performing chemical formation outside the battery case requires an immediate drying process to prevent oxidative deterioration of the negative electrode active material, and also requires charging for activation after battery assembly, making the battery manufacturing process complicated. , the cost was high.
これらの問題を解決する方法として電槽内で極板を化成
することが提案された。As a way to solve these problems, it has been proposed to chemically form the electrode plates inside the battery case.
すなわち、未化成の正極板と負極板および電解液を保持
吸収できるガラスマットセパレータからなる極板群を電
槽内に収容するとともに、過剰の希硫酸を極板群が温液

定の濃度と液量にする方法である。That is, a group of electrode plates consisting of an unformed positive electrode plate, a negative electrode plate, and a glass mat separator capable of holding and absorbing electrolyte was housed in a battery case, and excess dilute sulfuric acid was poured into the electrode group so that the electrode group became a hot liquid state. In addition, there is a method in which the electrolyte is charged to a predetermined concentration and volume upon completion of chemical formation.
発明が解決しようとする課題
この様な従来の構成は、電解液を多量に収容できる電池
は可能であるが、容積効率を高め、多量の希硫酸を加え
ると溢れてしまう電池には適用できないものである。Problems to be Solved by the Invention Although conventional configurations like this are possible for batteries that can accommodate a large amount of electrolyte, they cannot be applied to batteries that increase volumetric efficiency and would overflow if a large amount of dilute sulfuric acid was added. It is.
本発明は正極、負極とも未化成極板を用いて電槽化成を
行ない、過剰の電解液を加えることができない密閉形鉛
蓄電池の電槽化成を可能にしだも −のである。The present invention performs battery cell formation using unformed plates for both the positive and negative electrodes, thereby making it possible to form a battery case for a sealed lead-acid battery in which it is not possible to add an excess electrolyte.
課題を解決するための手段
本発明は極板群を収容した電槽内に、化成終了後所定量
に満たない液量の希硫酸を加え、充電した後、所定の電
解液量と濃度になる様に補液をするか、又は補液した後
、さらに再充電して所定の液量と濃度となる様にした化
成方法である。Means for Solving the Problems The present invention involves adding dilute sulfuric acid in an amount less than a predetermined amount after completion of chemical formation into a battery container housing a group of electrode plates, and after charging, a predetermined electrolyte amount and concentration is achieved. This is a chemical conversion method in which the liquid is replenished, or after the liquid is replenished, it is further recharged to reach a predetermined liquid volume and concentration.
作 用
このような本発明の化成方法では、大別して次の２通り
の作用がなされる。Function The chemical conversion method of the present invention has two main functions as follows.
（８）液量が比較的多い場合
充電効率の良い負極板は正極板より早く化成が完了する
ため、希硫酸に囲まれて正極板よりの酸素ガス吸収が少
ない状態で化成が完了する。しかし正極板を化成するた
めにさらに充電すると、電解液が分解減少し、所定の電
解液量に満たなくなるため電池としての容量が充分に得
られ°ない。これを防ぐためには補液をなせばよく、補
液により所定の電解液量および濃度にすることにより解
決できる。(8) When the amount of liquid is relatively large, the negative electrode plate with good charging efficiency completes formation earlier than the positive electrode plate, so the formation is completed in a state where the negative electrode plate is surrounded by dilute sulfuric acid and absorbs less oxygen gas than the positive electrode plate. However, if the battery is further charged to chemically form the positive electrode plate, the electrolytic solution decomposes and decreases, and the amount of electrolytic solution is less than the predetermined amount, so that a sufficient capacity as a battery cannot be obtained. In order to prevent this, it is sufficient to replace the electrolyte, and this problem can be solved by adjusting the amount and concentration of the electrolyte to a predetermined level by replacing the fluid.
（Ｂ） 液量が少ない場合
液量が少ない電池はガス吸収が良いため正極板から酸素
が発生し、それを負極板が吸収するため、負極板は充電
しながら放電するため、液量に見合った割合しか化成し
ない。この場合補液しただけでは、負極板は化成が完了
していないために容量は充分でない。しかし所定の電解
液量よりも多く補液し、充電することにより、負極板は
希硫酸に囲まれて正極板よりの酸素ガス吸収がなくなり
放電状態が解消されて化成が完了できる。(B) When the amount of liquid is small Batteries with a small amount of liquid have good gas absorption, so oxygen is generated from the positive electrode plate, which is absorbed by the negative electrode plate, so the negative electrode plate discharges while charging, so that the battery with a small amount of liquid has good gas absorption. Only a small proportion of the amount is converted. In this case, the capacity of the negative electrode plate is not sufficient even if only the liquid is replaced because the formation of the negative electrode plate is not completed. However, by replacing the electrolyte in an amount larger than a predetermined amount and charging the battery, the negative electrode plate is surrounded by dilute sulfuric acid, oxygen gas absorption from the positive electrode plate is eliminated, the discharge state is resolved, and the formation can be completed.

By simplifying the process, costs can be reduced.
