ていない。BACKGROUND OF THE INVENTION There are two types of sealed lead-acid batteries in which the negative electrode absorbs oxygen gas generated during battery charging: a retainer type and a gel type. The retainer type inserts a matte separator (glass separator) made of fine glass fiber between the positive and negative electrode plates, which holds the sulfuric acid electrolyte necessary for discharge and isolates the two electrodes. In recent years, it has become widely used as a backup power source for portable devices and computers, taking advantage of its characteristics such as no maintenance, no leakage, and no positioning. However, in the case of a lead-acid battery that uses a clad positive electrode plate, the unevenness of the surface of the electrode plate causes poor contact between the electrode plate and the glass separator, resulting in insufficient supply of electrolyte to the positive electrode plate. This type of sealed battery has not yet been put into practical use due to drawbacks such as poor discharge performance.
一方、ゲル式クラッド電池も、電池性能が液式に劣ると
いう欠点があった。On the other hand, gel-type clad batteries also have the disadvantage that their battery performance is inferior to liquid-type batteries.
課題を解決するための手段
本発明は上述した従来の密閉式鉛蓄電池の欠点を除去し

ろにある。以下本発明を実施例に基づいて説明する。Means for Solving the Problems The present invention eliminates the drawbacks of the conventional sealed lead-acid batteries mentioned above and provides an inexpensive sealed lead-acid battery with excellent discharge performance. Two or more protrusions are provided on each of the resin upper and lower joints of the positive electrode plate, and these protrusions maintain a constant distance from the negative electrode plate. Furthermore, an electrolyte holder is installed between the electrodes or around the electrode plate group. It is filled with fine silica powder. The present invention will be explained below based on examples.

きな特徴である。The height of this protrusion was set to be the same as the gap required between the positive electrode plate and the negative electrode plate when assembling the battery. This clad type positive electrode plate and a normal paste type negative electrode plate made of a pb-Ca-3n alloy lattice were laminated to prepare an electrode plate group. FIG. 2 shows a longitudinal cross-sectional view of the electrode plate group. A major feature of the sealed lead-acid battery according to the present invention is the use of fine silica powder as an electrolyte holder.

構造の連座となった。Therefore, in order to fill the space between the positive and negative electrode plates with silica powder at a constant thickness, it is important to keep the distance between the electrodes constant.
If this is not done properly, a short circuit may occur. Therefore, in the present invention, projections are provided on the upper and lower joints of the clad positive electrode plate, and as is clear from FIG. 2, the distance between the electrodes is maintained by the projections 4. If the distance between the electrodes was to be kept constant, it would be sufficient to simply increase the thickness of the joint, but this would make it difficult to fill the space between the electrodes with fine silica powder, so the joint had a structure with protrusions.
次に試作電池の容量試験を行った。供試電池は公称容量
４５Ａｈで、比較のために同じロットの正極および負極

。その結果を第１表に示す。Next, we conducted a capacity test on the prototype battery. The test battery had a nominal capacity of 45 Ah, and for comparison, conventional gel-type batteries and liquid-type batteries using positive and negative electrode plates from the same lot were also tested. The results are shown in Table 1.

効果によるものである。Table 1 From this test result, the low rate discharge capacity and high rate discharge capacity of the liquid type are higher than the gel type. ), the performance improved by 10 to 20% in both low rate discharge and high rate discharge. This is due to the synergistic effects of the electrolyte having a slightly higher specific gravity than the gel type, no need to use a separator that acts as a resistance during discharge, and excellent acid diffusion.

The industrial value of this device is enormous because it can greatly improve the discharge performance of conventional sealed lead-acid batteries.
