しい。When a battery having a plurality of stacked cells and the negative electrode terminal of the battery are grounded to a casing such as a buoy, the exhaust gas outlet and the electrolyte inlet are passed between each cell of the battery and between the battery and the casing. Leakage current flows and battery capacity is consumed.
Therefore, since the entrance and exit passages are desirably elongated so as to reduce the leakage current, the electrolyte inlet and the exhaust gas outlet and the passages connected to them should be made as long as possible, as long as the emission of products and gas cannot be prevented. Is desirable.

池電圧が変動する。In the conventional immersion type battery, various exhaust gas passages have been devised for the above-mentioned reasons. However, they have not been sufficiently considered to reduce the voltage fluctuation. That is, in the conventional immersion battery, when the generated gas is intermittently discharged from the exhaust gas outlet, the leakage current is affected by the behavior of the gas and fluctuates. When the leakage current changes, the battery voltage also changes. Also, when the generated gas cannot be discharged smoothly, the battery voltage fluctuates.

Therefore, it is necessary to make a battery with a small voltage fluctuation. Therefore, there has been a demand for an immersion-type battery in which the reaction products and generated gas are smoothly discharged, the leakage current is small, and the fluctuation of the battery voltage is small.

Instead, the above problem was solved by reducing the fluctuation of the battery voltage.

As a result, one or more bubbles generated one after another were always present in the exhaust gas passage of each cell. When one bubble is discharged, the next bubble moves to the place where the previous bubble was, thereby preventing the flow of the leakage current, and the fluctuation of the leakage current is minimized. It was found that the voltage fluctuation also became small.

入口部分である。Considering the above results, an exhaust gas outlet having a crank-shaped exhaust gas passage shape as shown in FIG. 3 and satisfying the following conditions is effective in reducing battery voltage fluctuation. I found that. In FIG. 3, reference numeral 10 denotes a vertical outlet portion of the exhaust gas outlet passage, 11 denotes a horizontal portion of the exhaust gas outlet passage, and 12 denotes a vertical inlet portion of the exhaust gas outlet passage.
【００１７】（１）各セル毎に排出ガス通路を設ける。(1) An exhaust gas passage is provided for each cell.
【００１８】この理由は、排出ガスの共通通路を設ける
と、共通通路を通ってセル間に漏洩電流が断続的に洩れ
るため、共通通路は設けないで各セル毎の排出ガス通路
で漏洩電流の変動を制御するためである。The reason for this is that if a common passage for the exhaust gas is provided, the leakage current intermittently leaks between the cells through the common passage. This is for controlling the fluctuation.
【００１９】（２）各セル毎の排出ガス通路の垂直出口

径３〜５ｍｍであり、直径３ｍｍの気泡が排出ガス通路
を塞ぐためには通路の断面積は７ｍｍ2 以下でなければ
ならないためである。This is because the size of the bubble to be discharged is 3 to 5 mm in diameter, and the cross-sectional area of the passage must be 7 mm 2 or less in order for the bubble of 3 mm in diameter to block the exhaust gas passage.
【００２１】（３）排出ガス通路の垂直出口部分の容積

以下とすることが望ましい。The reason is that if the vertical outlet portion is long, buoyancy acts on the gas discharge to increase the speed, the bubbles become small, and it becomes difficult to always close the exhaust gas passage with the bubbles. 14m, the volume of a bubble with a diameter of 3mm

It is desirable to make the following.

It is effective if the average volume of bubbles is 34 mm 3 or more,
In order to obtain a sufficient effect, the maximum bubble volume is 65m

If a common exhaust gas passage is not provided, the leakage current will increase in the conventional immersion battery, but the shape and dimensions of the exhaust gas passage of the present invention will prevent the increase in leakage current and smooth the discharge of gas and products, and reduce the voltage. A battery with little fluctuation could be made.
