【発明の詳細な説明】
産業上の利用分野
本発明は、自動車のエンジン始動等に用いられる密閉形
鉛蓄電池の製造法に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for manufacturing a sealed lead-acid battery used for starting an automobile engine, etc.
従来の技術
充電時に正極から発生する酸素ガスを負極で吸収除去す
る密閉形の、いわゆる負極吸収式鉛蓄電池は、その使用
電解液を電極およびセパレータに吸収保持されたものの
みに制限し、充電中に正極から発生する酸素ガスを負極
で吸収除去して水に戻し、電解液の減少を抑制する電池
である。このため酸霧の発生がなく、漏液も生じ難く、
軽量化が可能である等のすぐれた特長を有している。Conventional technology The so-called negative electrode absorption type lead-acid battery, which is a sealed type in which oxygen gas generated from the positive electrode is absorbed and removed by the negative electrode during charging, limits the electrolyte used to only that absorbed and retained by the electrodes and separators, and is used during charging. This is a battery that absorbs and removes oxygen gas generated from the positive electrode at the negative electrode and returns it to water, suppressing the loss of electrolyte. Therefore, there is no generation of acid mist, and leakage is less likely to occur.
It has excellent features such as being lightweight.
発明が解決しようとする問題点
この種の電池は負極が空気中の酸素により酸化されない
よう電池内は通常、安全弁により外気とは遮断されてい
る。この安全弁は過充電等で電池内がガス発生等で異常
に加圧状態になったとき開弁動作し、ガスを放出して圧
力を低減させるものである。Problems to be Solved by the Invention In this type of battery, the interior of the battery is usually isolated from the outside air by a safety valve to prevent the negative electrode from being oxidized by oxygen in the air. This safety valve opens when the inside of the battery becomes abnormally pressurized due to gas generation or the like due to overcharging, etc., and releases gas to reduce the pressure.
したがって、電池内は大気圧に対して減圧又は加圧の状
態にあり、この圧力差によって変形等しないよう、電槽
を強固な構造とする必要があった。Therefore, the inside of the battery is under a reduced or increased pressure with respect to atmospheric pressure, and the battery case needs to have a strong structure so as not to be deformed due to this pressure difference.
このため電槽の肉厚を通常の液入り鉛蓄電池にくらべ厚
くする必要があり、これが電池のコストアップの一要因
となっていた。For this reason, the wall thickness of the battery case had to be thicker than that of a normal liquid-filled lead-acid battery, which was one of the factors that increased the cost of the battery.
本発明は上記の欠点を解決するもので、電池内圧を常に
大気圧と同じにし、電槽強度を通常の液入り鉛蓄電池と
同程度にすることを可能とし、なおかつ空気中の酸素ガ
スによる負極の酸化を実用上問題ない程度まで抑制する
ことを目的とするものである。The present invention solves the above-mentioned drawbacks, and makes it possible to keep the internal pressure of the battery at all times the same as atmospheric pressure, to make the strength of the battery case comparable to that of ordinary liquid-filled lead-acid batteries, and to make it possible to maintain a negative electrode using oxygen gas in the air. The purpose is to suppress the oxidation of oxidation to a level that poses no practical problems.
問題点を解決するだめの手段
本発明では従来の安全弁のかわりに、電池容器の例えば
蓋に微細孔径の通気路(キャピラリー)を設け、電池内
への空気の流入出を微量のものとするとともに、電池完
成時点で通気路より不活性ガスを送り込んで電池内のガ
スを不活性ガスに置換するものであり、電池が再度充電
されるまでの間、負極を不活性ガスで包んでその酸化を
抑制したものである。Means to Solve the Problem In the present invention, instead of the conventional safety valve, a vent passage (capillary) with a micropore diameter is provided in the lid of the battery container, for example, to reduce the amount of air flowing into and out of the battery. When the battery is completed, inert gas is sent through the ventilation passage to replace the gas inside the battery, and the negative electrode is wrapped in inert gas to prevent oxidation until the battery is recharged. It was suppressed.
作用
この方法によれば、一度電池が充電されたあとは負極の
酸素ガス吸収により空気が電池内に導入されるため、不
活性ガスで包まれているとは云え安全弁をそなえた場合
よりも負極の酸化は多くなるが、たとえば自動車用途等
ひんばんに充電される場合は直ちに充電により酸化され
た負極が還元されるため実用上は全く問題とならなく、
電池容器の肉厚もこれまでより薄くすることで密閉形鉛
蓄電池としての機能を確保できるものである。According to this method, once the battery is charged, air is introduced into the battery due to the absorption of oxygen gas by the negative electrode, so even though the battery is surrounded by inert gas, the negative electrode However, if the battery is frequently charged, such as when used in automobiles, the oxidized negative electrode is immediately reduced by charging, so this is not a practical problem at all.
By making the wall thickness of the battery container thinner than before, it is possible to ensure its function as a sealed lead-acid battery.
実施例
まず、電槽と中蓋をポリプロピレンで形成し、電槽の各
セル室内に極板群を挿入し、極板とセパレータに必要量
の電解液を保持させ遊離の電解液は存在しない状態で孔
径2間、長さ15wnのキャピラリー管を各セル室に対
応して設けた中蓋と上蓋とで電槽を封口する。Example: First, the battery case and inner lid are made of polypropylene, and a group of electrode plates is inserted into each cell chamber of the battery case, and the electrode plates and separators hold the required amount of electrolyte, so that there is no free electrolyte. Then, a capillary tube with a hole diameter of 2 mm and a length of 15 wn was provided to cover each cell chamber, and the battery case was sealed with an inner lid and an upper lid.
そして化成充電を施して電池を完成させた後、中蓋、上
蓋間の排気路及び前記のキャピラリー管からなる通気路
を利用して各セル室内にチッ素ガスを送り込み、電池内
部を不活性なチッ素ガスで置換して密閉形鉛蓄電池人を
作成した。After completing the battery by chemical charging, nitrogen gas is sent into each cell chamber using the exhaust path between the inner lid and the top lid, and the ventilation path consisting of the capillary tube described above, to inert the inside of the battery. A sealed lead-acid battery was created by replacing it with nitrogen gas.
比較のため、ムの電池においてチッ素ガスの置換を行な
わなかったものをB、これまでの中蓋に孔径5閣の排気
筒を立設し、これにキャップ状ゴム弁をかぶせたものC
,Cの電池と同構造で電池内部をチッ素ガスで置換した
ものD、中蓋に孔径6閣の常開形通気孔を設け、電池内
部のガスは完成時のままとしたものJEの電池で完成時
に電池内部をチッ素ガスで置換したものFをそれぞれ用
意し、常温に1年間放置後の残存容量を比較したところ
次表の通りであった。For comparison, B is a battery with no nitrogen gas replacement, and C is a battery in which an exhaust pipe with five hole diameters is installed on the inner lid and a cap-shaped rubber valve is placed over it.
, the same structure as the battery in C, but with the inside of the battery replaced with nitrogen gas; D, the battery with a permanently open vent hole of 6 holes in the inner lid, and the gas inside the battery as it was when completed; the battery in JE. When completed, the inside of the battery was replaced with nitrogen gas (F) was prepared, and the remaining capacity after being left at room temperature for one year was compared, and the results were as shown in the following table.
なお電池A〜Fはいずれも30Ahの公称容量をもつも
のとし、残存容量は初期の6時間率容量に対して残存す
る容量を100分率で示した。Batteries A to F all have a nominal capacity of 30 Ah, and the remaining capacity is expressed as a percentage of the initial 6-hour rate capacity.
この表から明らかな通り、常開形通気孔を設けた電池E
、Fではその雰囲気に関係なく、保存期間中に外部から
の酸素ガスの電池内への侵入と電解液の蒸発逸散により
1嗣後には残存容量は0であった。As is clear from this table, battery E with a normally open vent hole
, F, regardless of the atmosphere, the remaining capacity was 0 after one generation due to the intrusion of oxygen gas from the outside into the battery and the evaporation of the electrolyte during the storage period.
又キャップ形ゴム弁を備えた電池C,Dはゴム弁により
気密が保てるため残存容量は人よりも多く残っていたが
、充放電による電池容器の加圧減圧に耐えるよう電池容
器を肉厚に構成しなければならなく、又ゴム弁の設置と
その抜止め策を講じる必要があり、コストアップと電池
組立作業性が煩雑となるという問題がある。In addition, batteries C and D equipped with cap-shaped rubber valves had more remaining capacity than a human battery because the rubber valve could maintain airtightness, but the battery container was made thicker to withstand the pressure and depressurization of the battery container during charging and discharging. In addition, it is necessary to install a rubber valve and take measures to prevent its removal, which raises the problem of increased costs and complicated battery assembly work.
さらにムの電池と同様な構造で電池内部をチッ素ガスで
置換しなかったBは、保存により通気路を通じての酸素
の電池内への侵入があり、負極の酸化劣化により残存容
量は23%とムの半分以下であった。Furthermore, in B, which had a similar structure to the B battery but did not replace the inside of the battery with nitrogen gas, oxygen entered the battery through the ventilation path during storage, and the remaining capacity was 23% due to oxidation deterioration of the negative electrode. It was less than half of the time.
電池ムはキャップ形ゴム弁を備えることなく、キャピラ
リー管からなる微細孔径の通気路を設けるだけでチッ素
ガスで包まれた極板群のとくに負極の酸化劣化と電解液
の蒸発逸散も抑制されるため初期の54%の容量を残存
していた。The battery system does not require a cap-shaped rubber valve, and only has a capillary tube with a fine-pore ventilation path to suppress oxidative deterioration of the electrode plates, especially the negative electrode, which are surrounded by nitrogen gas, and evaporation of the electrolyte. As a result, 54% of its original capacity remained.
又この人の電池では電池容器の内外が常に同じ圧力にあ
るため、キャップ形ゴム弁を備えたもののように加圧、
減圧の圧力変化に耐えるために電池容器を肉厚とする必
要はなく、軽量の電池容器とすることができる。Also, in this person's battery, the pressure inside and outside of the battery container is always the same, so pressurization, such as one equipped with a cap-shaped rubber valve,
It is not necessary to make the battery container thick in order to withstand pressure changes due to reduced pressure, and the battery container can be made lightweight.
なお電池内部を置換する不活性ガスは、実施例ではチッ
素ガスを示したが、この他にアルゴムガスなど負極酸化
を抑制できるガスであれば使用可能である。The inert gas that replaces the inside of the battery is nitrogen gas in the examples, but any other gas that can suppress negative electrode oxidation, such as al rubber gas, can be used.

よりも肉薄で軽量なものにできる利点がある。Effects of the Invention As described above, the sealed lead-acid battery of the present invention achieves a negative electrode absorption type lead-acid battery with gas conduction inside and outside the battery due to the air passages with micropores, and pressure changes inside and outside the battery are prevented. This has the advantage that the battery container can be made thinner and lighter than conventional sealed lead-acid batteries.
