Embodiment 1

[0014] figure 1 The shown coiled rectangular pole group has different length and width sides, and its cross-sectional shape is a rectangle. The positive electrode plate 1 and the negative electrode plate 2 used in the electrode group are cut into strips of equal length and width. During production, the positive electrode plate 1 and the negative electrode plate 2 are aligned and stacked together, and wound in a counterclockwise direction along with a predetermined forming die. Under the premise that the sizes of the positive plate 1 and the negative plate 2 are determined, the number of winding layers depends on the capacity of the supporting battery. In this embodiment, the cross-sectional shape of the coiled pole group is a unequal-sided rectangle, and such a rectangular pole group is easy to fit closely with a rectangular battery case, thereby achieving the purpose of making full use of the internal space.

Embodiment 2

[0016] figure 2 The long and wide sides of the coiled rectangular pole group shown are equal in size, and its cross-sectional shape is a square. Except that the aspect ratio of the pole group is different from that of Embodiment 1, the other structural features are the same, and the effect of the applied technology is also the same, so the description will not be repeated.

Abstract

The invention discloses a coiled rectangular pole group. The coiled rectangular pole group consists of positive plates and negative plates. The positive plates and the negative plates are strap-shaped plate products with the equal lengths and the equal widths, and the positive plates and the negative plates which are stacked neatly are jointly wound and formed in a rectangular manner. The positive plates and the negative plates are jointly wound counterclockwise, and can also be wound clockwise. The radio of the length to the width of the manufactured rectangular pole group can be adjusted as needed. The structure is easily matched. The rectangular pole group is easily and tightly matched with a rectangular storage battery shell. The pole group is bent, wound and formed. A used forming die is simple; industrial production is easy to realize; the manufacturing efficiency is high; and the quality is stable.

Description

technical field [0001] The invention relates to a pole group of a lead-acid storage battery. Specifically, the invention relates to a winding type pole group, especially a winding rectangular pole group. The technical proposal belongs to the technical field of lead-acid storage battery manufacturing. Background technique [0002] The electrode group is the core component of the lead-acid battery. The traditional lead-acid battery built-in electrode group mainly has two structural types, one is formed by multi-layer lamination, and the other is formed by winding. The pole group formed by multi-layer lamination is a rectangular body. Although the structure of this form of pole group is very simple, the manufacturing process is long, time-consuming, and bulky. The biggest problem is to determine the size of the single plate according to the size of the supporting battery. Batteries of different specifications need to develop grid molds of different sizes. Winding forming is an...
