板変形の著しい陽極板は上辺が膨れ上つて陰極集
電部と接触し内部短絡を生じる懸念がある。 As the charge/discharge cycle progresses, the active material of paste-type electrode plates for lead-acid batteries expands and falls off, degrading the capacity. Therefore, a separator is inserted between the negative and anode plates, and the batteries are stacked and stored in a battery case under pressure. However, there is no mechanical regulation on the upper side of the electrode plate, and there is a concern that the upper side of an anode plate, which is particularly severely deformed, may bulge and come into contact with the cathode current collector, causing an internal short circuit.
そこで従来より集電板と極板群上面との間に絶

2 fits into the hollow part 25 of the terminal pillars 15, 16 and is always closed, but when gas is generated inside the battery, the 4th
As shown by the arrow in the figure, the gas passes through the through hole 23 of the insulating spacer 20, the gas pressure forms a gap between the protrusion and the terminal posts 15, 16, and the gas is released from the hollow part 25 through the gap. .
尚、実施例では一対の絶縁スペーサーを用いる
場合を示したが陰極板に比して陽極板の膨脹変形
