Electrochemical oxidation, or corrosion, of the lead-antimony alloy, which is the material of the pole, easily occurs at the pole pillar sealing part.
The effective cross-sectional area of the pole column is reduced, and corrosion products (mainly PbSO 4 and α-PbO 2 ) protrude outward from the pole column. For this reason, conventional lead-acid batteries had the drawback that expansion of the pole column due to corrosion occurred at the pole column sealing portion, pressure increased, and cracks occurred in the battery case top 2.

There was also the drawback of doing so.
