In particular, the present invention relates to a lead-acid battery pole pole that suppresses corrosion of the positive pole pole and improves reliability.

いる。As is clear from FIG. 2, the pole part of the lead-acid battery has a pole pole 1, which passes through the battery case top cover 2 and protrudes to the outside of the battery case, and passes through the gasket 7 to the top cover. 2 has a pillar sealing structure attached to it with a nut 3. The other tip of the pole column 1 is connected to an electrode plate 4, and this electrode plate 4 is placed in the electrolytic solution 5 by /j1/J! i have been

。The pole pole 1 plays the role of a conductor that receives electrical energy generated by an electrochemical reaction from the electrode plate 4 and supplies it to an external load, and unlike the electrode plate 4, the pole pole 1 itself does not undergo any chemical changes. It is desirable not to receive.

った。However, in the conventional lead-acid battery shown in Fig. 2, electrolyte is intermittently supplied to the pole pillar sealing part, which is the gap between the pole pole 1 and the battery case top cover 2, mainly due to the generation of electrolyte mist. is carried out, and the electrolyte stagnates there. Under these conditions, electrochemical oxidation, or corrosion, of the lead-antimony alloy, which is the material of the pole, easily occurs at the pole pillar sealing part, reducing the effective cross-sectional area of the pole and causing corrosion products ( Mainly Pb5Oa and α-Pb02) protrude outward from the pole column. For this reason, conventional lead-acid batteries have the drawback that expansion of the pole column due to corrosion occurs at the pole column sealing portion, pressure increases, and cracks occur in the battery case top 2.

負荷への電力供給を遮断するという欠点もあった。At the same time, due to the occurrence of corrosion, the resistance of the pole pole 1 at the pole pole sealing part increases, and in extreme cases, the pole pole may melt due to heat during discharge, resulting in the battery exploding.
Another drawback was that it cut off the power supply to the load.

ていないのが現状である。In order to eliminate such drawbacks, various attempts have been made to prevent corrosion by eliminating the gap between the pole pole 1 and the top cover 2 and preventing the electrolyte 5 from entering the pole pole sealing part. . However, it is impossible to completely prevent the intrusion of the electrolytic solution 5, and it is currently not possible to effectively prevent corrosion.
