Description of the Related Art When a lead-acid battery is used in a hybrid electric vehicle, that is, an electric vehicle powered by both a storage battery and gasoline, a large current is discharged from the lead-acid battery every time the vehicle is accelerated and charged when the vehicle is decelerated. Because of this, excellent high-rate rapid discharge characteristics and long life performance are required. In order to improve the high-rate rapid discharge characteristics, the power density must be high. The power density is proportional to the surface area of the electrode plate. Therefore, in order to increase the output density per unit volume, it is only necessary to make the electrodes thin and increase the number of the electrodes. However, the electrode plate of a conventional lead-acid battery usually uses a cast-type or expand-type current collector.
It was difficult to obtain a thin electrode plate having a thickness of not more than mm.

が増え、密着力が増す。When the surface of the lead foil is oxidized as in claim 1, it becomes lead dioxide and becomes coarse. Since lead dioxide and the paste active material are hardly adhered, lead dioxide is reduced to lead. In this way, since the lead foil surface is rough lead, the active material bites into the lead foil surface and has excellent adhesion to lead. Further, since the surface area of the lead foil becomes large and the contact area with the active material becomes large, the number of parts integrated by the aging reaction increases, and the adhesive strength increases.

After washing these three types of lead foils with a mannit solution, the mass of each was measured. Then, before the anodic oxidation was performed, the mass measured beforehand was subtracted to determine the increase in each mass, and this was divided by the surface area to determine the thickness of the corroded layer.

In this investigation, the electrode plate was dropped from a plane having a height of 20 cm, and the amount of the active material dropped was measured. FIG. 2 shows the relationship between the type of current collector and the amount of active material falling off. From this result, it was found that there was a large difference between the corroded and uncorroded ones, but the corroded one had almost no difference due to the thickness of the corroded layer.
