The present invention relates to a method of manufacturing an electrode plate group using one paste-type electrode plate, a positive electrode plate and a negative electrode plate, and involves winding connected integral positive and negative electrode plates having a plurality of ears into an oval shape. It is characterized by improving the utilization rate of active materials and battery voltage. Conventional methods for producing electrode plates for lead-acid batteries include using a cast grid, or forming a sheet made of lead or lead alloy into a continuous grid by expanding or punching, and then filling it with a paste-like active material. After that, a method of producing electrode plates was developed in which the plates were cut into plates with one ear using a press method or a rotary cutter method. After separating the positive and negative electrode plates made in this way with a separator to form a group of electrode plates, the ears of each are welded using a gas burner or cast-on method to create a single cell, which is used to build a battery. It was assembled. However, in batteries made in this way, each electrode plate is connected only at the ears, and when discharged, the utilization rate of the active material is concentrated around the ears, and the utilization rate of the total active material is low. However, the drawback was that the voltage drop due to discharge was large. The present invention solves this problem by using a continuous, integrally molded positive and negative electrode plate having a plurality of ears, and forming it into an oval shape with a parallel part and a curved part, with the ears of the same polarity at the corresponding positions. This problem was solved by winding the electrodes so that the polarity is the same, and welding the ears of the same polarity at corresponding positions to form a group of electrode plates. The details will be explained below in Examples. FIG. 1 is a diagram showing positive and negative electrode plates according to the present invention, which are made of a continuous band-like structure in which a lattice having a plurality of ears 1 is continuously manufactured by expanding and filled with a paste-like active material. A positive electrode plate 2 and a negative electrode plate 3 made of molded electrode plates are interposed with a separator 4 between them as shown in FIG. After winding it into an oval shape so that it is located at positions 5 and 5', the connecting body 6,
7 are welded to ears 8 and 9 of the same polarity at positions 5 and 5' using a gas burner or the like to form a single cell. This single cell is assembled into a battery case, and the cells are connected to form a lead-acid battery. In addition, the following table shows the active material utilization rate and voltage drop characteristics of the battery according to the present invention and a conventional battery configured with an electrode plate having one ear.

This is not only in the vicinity of the ears connected to the connecting body, but as is clear from Figure 1, both the positive and negative electrode plates are connected laterally at the upper band-shaped unprocessed part (frame part), and the utilization rate of the paste active material is increased. This is because the whole body was elevated. As explained above, the present invention involves winding a continuous integrally molded electrode plate having a plurality of ears into an oval shape having parallel parts and curved parts so that the ears of the same polarity are in corresponding positions. The feature is that the ears of the same polarity are welded to each other, and the current collecting effect is enhanced and the active material utilization rate and voltage drop characteristics are improved.
