こなっている。2. Description of the Related Art In a lead storage battery, when overcharging is performed, water in an electrolytic solution is electrolyzed as a side reaction separately from a charging reaction of an active material to generate oxygen gas and hydrogen gas. Therefore, when a spark is generated outside the battery, there is a risk that the battery may catch fire. Conventionally, the following measures have been taken to solve this problem. For example, installing an explosion-proof filter in the gas exhaust path or releasing gas inside the battery when the battery internal pressure rises above a specified value so that the gas does not stay in the battery and the concentration does not rise so that hydrogen gas can explode For example, a liquid port plug provided with an exhaust valve for exhausting the gas or a catalyst plug for returning the oxygen and hydrogen gas to water and returning the water to the cell chamber is used. Also,
When the vehicle travels, static electricity is charged to the battery due to air friction, and there is a danger of explosion due to electrostatic spark discharge with a nearby object. To solve this problem, the battery is electrically connected to the negative terminal of the battery and the body of the vehicle to discharge static electricity into the air as needed, thereby preventing gas explosion in the battery.

予防策だけでは防止することができなかった。However, battery replacement,
During inspection, cleaning, or transportation, static electricity is charged to the battery, and if a non-conductive resin, human body, or metal whose opposite charge or one of them is grounded comes close to the battery, static electricity may be generated between these and the battery electrolyte. Sparks were generated by spark discharge, and the sparks passed through the gap between the liquid port plug and the lid, propagated inside the battery, and ignited hydrogen gas in the battery, possibly causing explosion and damage of the battery. On the other hand, measures have been taken to increase the liquid tightness and air tightness by interposing a rubber packing between the exhaust pipe and the liquid port plug. However, this measure alone is not sufficient.Especially, when the electrolytic solution in the battery crawls up through the fitting surface between the liquid port stopper and the exhaust pipe and reaches the lower surface of the rubber packing,
The static electricity reaches the inside of the battery through the electrolytic solution adhering to the rubber packing, which tends to cause explosion in the battery. These explosions due to static electricity could not be prevented only by the above-described preventive measures against ignition from outside the battery.

However, such measures alone did not completely prevent battery damage, and required other measures, such as reducing the upper space in the battery or filling it with gas to reduce the gas retention space. However, such measures have had other problems such as an increase in cost.

蓄電池破損実験を実施した。Here, the transition of the hydrogen concentration in the battery from immediately after charging to 30 minutes later was measured by a hydrogen gas concentration meter (XP-314 manufactured by Shin-Cosmos Electric). The hydrogen gas concentration in the battery for 30 minutes after charging was in the range of about 12 to 18%, and there was almost no change in the gas concentration during this period. The hydrogen gas concentration immediately before the experiment was 0% outside the liquid port plug and 18% inside the liquid port plug. From this, it was confirmed that the hydrogen gas concentration (4 to 75%) that could explode in the battery and in the liquid port plug. As a method of applying static electricity, a static electricity generating device (STATILER 20-D manufactured by Shisido Electrostatic Co., Ltd.)
The negative charge generated in P) was applied to an aluminum plate attached to the long side surface of the storage battery, and the battery was gradually charged with an electrostatic voltage. At the same time, at each set electrostatic voltage, a metal clip connected to a ground wire having a ground resistance of 48Ω was gradually approached to the lower edge 7a of the rubber packing portion of the liquid stopper 6 to measure a distance at which electrostatic spark discharge occurs. Here, when the range of the charge amount of the test battery was examined (the charge amount was measured by rubbing the battery lid with a PP resin, a human body (hand), polycarbonate, or the like), the value was -2 to -16 KV. Therefore, the setting range of the electrostatic voltage was set to -1 to -18 KV. In addition, since some of the comparative batteries had the lower surface 7b of the rubber packing portion of the liquid port stopper wet with the electrolytic solution, the other was not subjected to the storage battery damage experiment.

Under the conditions shown in (1), electrostatic spark discharge occurred. Furthermore, it was found that the electrostatic spark discharge was most likely to occur when the lower surface 7b of the rubber packing portion of the liquid port stopper was wet with the electrolytic solution. In the comparative battery, the lid was lifted due to the explosion in all the batteries in which the electrostatic spark discharge occurred, and the short side of the battery case was cracked. On the other hand, the battery of the present invention
No electrostatic spark discharge occurred in the entire electrostatic voltage range applied to the battery.
