３の構成が一般的である。Conventional technology A conventional sealed lead-acid battery is disclosed in Japanese Patent Application Laid-Open No. 60-205958, in order to take advantage of its thinness, especially compared to thin batteries.
It is advantageous to have a structure in which the electrode plate group is wrapped in a film sack as proposed in Japanese Patent Application Laid-Open No. 60-230354. By the way, since it is difficult to make the cathode plate extremely thin, as shown in Fig. 2, an anode plate 2 is placed on one side of the electrolyte holder 1t and a cathode plate on the other side. 3 configuration is common.

高率放電の場合その低下は著しい。Problems to be Solved by the Invention When the electrode plate group consists of one anode plate and one cathode plate, the reaction part as a battery is limited to only one side, and one anode plate is replaced by two cathode plates.
When sandwiching between two sheets, the active material utilization rate decreases, especially in the case of high rate discharge.

One or more anode plates and one or more cathode plates are arranged in parallel on one side of the electrolyte holder', and corresponding cathode plates and anode plates are arranged in parallel on the other side, and an electrolyte holder is placed on both outer sides. The polar plate group configuration has a tW characteristic with a body present.

し、利用率を高めていることによる。As shown in FIG. 1, an anode plate 2 and a cathode plate 3 are arranged in parallel on one side with the electrolyte holder lt centered on the same plane, and a corresponding cathode plate 3 and anode plate 2 are arranged on the opposite side. In addition, an electrode plate group was prepared in which electrolyte holders 1' were provided on both outer sides. For comparison, a sealed lead-acid battery with a conventional plate group configuration of one anode plate and one cathode plate with the same thickness and area was also fabricated. The shape of the 14L pond is made of film.
The thickness was 4+m using the motherboard method. Electrolyte specific gravity 1.3
55Th was used, and the explosion method of the electrode plate followed a conventional method. In the electrode plate group structure of the present invention, the anode plates 2 and the cathode plates 3 are connected to each other by creating bridges. Conventionally, the polar pillars were one yang and one yin. 1. After repeating several cycles with OCA current, 3. OCA, 1. OCA, 0.5CA, 0. The ICA was discharged and its capacity was compared. FIG. 3 shows the capacity ratio between the conventional product and the product of the present invention. As is clear from the figure, the product of the present invention has a higher capacity than the conventional product, and it can be seen that the product of the present invention is extremely advantageous, especially in high rate discharge. The reason for this is that due to the supply of liquid from both outer retainers, the anode plate and the cathode plate on the parallel surfaces react on the back surface of the electrode plates, increasing the utilization rate.

The active material utilization rate can be improved by utilizing the back surface of the electrode plate, which is not used in the one-plate, one-cathode configuration, and a higher capacity can be achieved without increasing the thickness of the battery.
