子体に充填して製造される。Conventional technology and its problems The negative electrode plate of a lead-acid battery is made by adding organic substances such as lignin and humic acid, Ba5Oa, and carbon black to lead powder, which is a lead oxide, and kneading it with dilute sulfuric acid to form a base, and a lattice, which is a lead alloy. Manufactured by filling the body.

となることもある。On the other hand, when charging a lead battery, the upper part of the seed root has a small voltage +n loss due to the resistance of the lattice body and is easily charged, but the lower part of the electrode plate has a large voltage loss and is difficult to charge. This is not a problem for applications where the battery is sufficiently charged at a constant current, but when charging is performed with a limited voltage, such as with automotive lead-acid batteries, charging may not progress sufficiently, especially in winter when temperatures are low. ! First, the charged state of the active material becomes uneven between the l: part and the lower part of the electrode plate, and S04 accumulates at the lower part of the electrode plate along with the charge, making it impossible to perform 11'ifi. This may lead to premature end of life.

Insert the root into container 3 containing carbon black and
Carbon black was attached to the surface of the A root, and it was pressed onto the monopole paste using an L-lebrass, which was then aged and dried. At this time, three types were prepared: B, in which carbon black was attached only to the upper part of the negative electrode plate, C, in which carbon black was attached only to the lower part, and D, in which carbon black was attached only to the lower part. For comparison, we also assembled an automobile battery (12V) with a nominal capacity of 28A h (5 hours' $) using four types of negative plates, including negative plate A to which no carbon black was attached, and performed battery cell formation. The electrolytic liquid 1p was adjusted to 1.28 (20° C.) and subjected to the charge/discharge test described below.

It shows the number of charging and discharging times when the amount of Pb3O4 in the active material on the upper and lower parts of the plate and the amount of discharge '8 become 50% or less of the nominal capacity. Note that the discharge capacity will reach 50% by the 10th charge/discharge.

After charging, the Ptl504Ffi at the top of the negative electrode plate was 10%, but that at the bottom was 49-54%, indicating that the ultimate charging state was uneven between the top and bottom.

ここでは負極板のＲＩＳＯ４ｆｉｔについてのみ述べた
が、正橿板についても同様の傾向を示した。I also learned that the number of charging and discharging times that the discharge capacity becomes 50% or less of the nominal capacity is 14. In battery 2 assembled using a negative electrode plate with carbon black attached to the upper part of the electrode plate, the number of charging and discharging times at which the discharge sound h1 reaches 50% or more of the nominal capacity is 9 times, which is shorter than the conventional product (1 pole). Pb SO4m in active material
It can be seen from this that the charging state of the electrode plate is even more uneven than that of the conventional product. On the other hand, in Battery 3 assembled using the negative electrode plate with carbon black attached only to the lower part of the electrode plate according to the present invention, the Pb5Oaffi in the active material was 12% in the upper part, compared to the conventional one. However, at the bottom, it was 23%, which was significantly lower than the conventional product, and the difference in the state of charge between the upper and lower parts of the electrode plate had almost disappeared. By attaching it to the bottom of the plate, the overvoltage required for charging at the bottom of the plate was reduced, which offset the loss caused by the resistance of the grid, and the charging reaction proceeded more uniformly between the top and bottom of the plate. Furthermore, it is thought that the discharging reaction was able to occur uniformly by making this charging reaction uniform, but the number of charging and discharging times at which the discharge capacity became 50% or less of the nominal capacity was also 19 to 22. This has significantly improved.
Although only the negative electrode plate RISO4fit was described here, the positive electrode plate also showed a similar tendency.

It was done. In addition, in this example, as shown in Figure 1, carbon black was attached to the bottom of -L in two sections, but the same effect was applied to J and sea urchin adhesion as shown in Figure 2.
