Then, the prepared electrode plate group was inserted into a battery case so that the positive / negative electrode plate and the separator were in the vertical direction, and then dilute sulfuric acid was injected into the separator as an electrolyte to form a chemical. The battery case has a hole on the upper surface, and the battery terminal is exposed to the outside through the hole. After that, a sol solution composed of dilute sulfuric acid and colloidal silica was injected between the electrode group and the battery case to gel. Thus, a gel-retainer hybrid battery was manufactured. The nominal voltage of the battery is 2V,
Nominal capacity is 30 Ah.

表１に示す。The number of charge / discharge cycles until the discharge capacity was reduced to 80% or less of the nominal capacity was examined by appropriately measuring the discharge capacity of the batteries in each direction while repeating charge / discharge. Here, the discharge is 10A (1 / 3C
A) was carried out at a constant current of A) for 2.4 hours. Charging was carried out at a constant current of 10 A for 90% of the amount of discharge, and then at a constant current of 1.5 A for 20% of the amount of discharge. The discharge capacity was measured at 10A
This was achieved by discharging at a constant current of (1/3 CA) for 2.4 hours. Further, the same test was performed on the retainer type battery.

解液が多く減少したことにあると考えられる。As shown in Table 1, in the gel-retainer hybrid battery, the life performance was remarkably good in the horizontal direction, at 20 degrees up and 20 degrees down. The reason seems to be that the electrolyte is uniformly distributed by optimizing the orientation of the battery. The life performance of the retainer-type battery is inferior to that of the gel-retainer hybrid-type battery, which is considered to be due to the fact that the temperature inside the battery increases and the amount of the electrolyte decreases largely.
