The first step is to prepare a porous alloy sheet.
As shown in FIG. 1, the material is fed into the impregnating apparatus 2 heated to 150 DEG C. through a sheet supply port 3 provided at the upper part thereof. Next, the molten metal is fed into the impregnating apparatus 2 from the molten metal supply pipes 4 and 5 provided on both sides of the impregnating apparatus 2, while degassing with a suction vibro directly connected to a vacuum pump.
A molten metal containing 1% Sb is injected. By this operation, the above-mentioned p b -3

極板より活物質の利用率か向上する。Next, this electrode plate base 12 is filled with paste to form an electrode plate. Since the base 12 of the electrode plate manufactured in this way is made of a porous alloy having mutually conductive spaces, the electrolyte is also present in the pores of the base 12, so that the electrolyte is present in the pores of the base 12. The nearby active material participates in the discharge and becomes less active, improving the active material utilization rate compared to conventional electrode plates.

In addition, in the battery according to the present invention, in order to prevent a large voltage drop, which is a disadvantage when a porous lead alloy is used for the electrode plate substrate, the electrode plate substrate is
After making the ear part 9 and upper frame 1o of 2 solid,
The voltage drop for a 100A discharge at -15°C was α5v, which was not so large, and the discharge duration was 27 seconds longer due to the increased utilization of the positive electrode plate. Furthermore, since the surface of the electrode plate substrate 12 of the present invention is made up of part of a large number of holes, the surface is highly uneven and the adhesion to the active material is better than that of conventional electrode plates, allowing one assembly and one process. Shedding of the active material inside was also significantly reduced.
