Description
【発明の詳細な説明】
本発明は特ζこ小形密閉式鉛蓄電池の改良１こ係り、そ
の目的とするところは特性向上を図るζこある。DETAILED DESCRIPTION OF THE INVENTION The present invention is specifically concerned with improving a small sealed lead-acid battery, and its purpose is to improve its characteristics.
の放置即ち、過放電放置後の充電電流か流れ難へ く、充電時間を長く要する欠点を有していた。In other words, after over-discharging, the charging current becomes difficult to flow. However, it had the disadvantage of requiring a long charging time.
これは過放電放置後では電解液中に硫酸か殆ど存在せず
、ＷＡ電解液抵抗増大するからである。This is because after over-discharging, there is almost no sulfuric acid in the electrolyte, and the resistance of the WA electrolyte increases.
本発明は上記の如き点ＩＣ鑑み、極板ペースト中に、ナ
トリウムをはじめとするアルカリ金属あるいはアルカリ
土類金属の硫酸塩を添加し。In view of the above-mentioned points of IC, the present invention adds sulfates of alkali metals or alkaline earth metals, including sodium, to the electrode plate paste.
これか電解液中１こ溶出することにより、過放電放置中
の電解液抵抗の増大を抑制せしめ、電池の充電時間を短
縮することＩこある。By eluting one of these into the electrolyte, it is possible to suppress the increase in electrolyte resistance during overdischarge and shorten the charging time of the battery.
次に本発明の一実施例を説明する。Next, one embodiment of the present invention will be described.

７ Ｗ ｔ％に相当する硫酸ナトリウムを添加した場
合の過放電放置後の充電電流曲線を示したものである。The drawing shows the weight of the electrolyte in the conventional battery and electrode plate paste, Q,
This figure shows a charging current curve after overdischarging when sodium sulfate corresponding to 7 W t % is added.

きた。この効果は、添加量Ｑ、 ｌ ｗ ｔ ４以上の
範囲でみられ、これ以下では電解液抵抗の増大を抑制す
ることはできない。In conventional battery A, it took about 2 hours to reach IA, which is the cutting current. In battery B, which added sodium sulfate according to the present invention, good results were obtained as it reached IA within 10 minutes. , we were able to shorten the charging time by 2 hours. This effect is seen in the range of addition amount Q, l w t of 4 or more, and below this, increase in electrolyte resistance cannot be suppressed.
上述のように本発明によれば、過放電放置後の充電時間
