Embodiment Construction

[0031] as attached figure 1 As shown, two polar plates with opposite polarities are connected by a lead wire coated with an insulating substance, and folded into a U shape at the lead wire to form a bipolar plate 2. There are 11 bipolar plates 2 in total; inside the unipolar plate 1a Place the U-shaped bipolar plates 2 vertically, with the opposite polarity side adjacent to the monopolar plate 1a, and place the bipolar plates in sequence. A total of 11 bipolar plates 2 are stacked to ensure that the polarities are staggered, and one is placed outside the last bipolar plate. The unipolar plate 1b with opposite polarity; the separator is cut into 2.1 times the separator 3 of the side area of ​​each plate, a total of 24 pieces are cut, and then folded into a V shape to enclose the aforementioned 24 plates respectively; Cut the insulating plastic film into 24 film sheets slightly larger than the side area of ​​each pole plate, and stick these films on the outer surface of the corr...

Abstract

This invention discloses a folded polar plate lead acid battery and its making method, among which the lead wire connecting two plates is folded into u-shape and monopolar and bipolar plates are arranged in the box in sequence according to the matched polarities, a V-shaped diaphragm wraps both sides of each plate, insulation bag sleeve two adjacent polar plates and the diaphragm warapping the polar plates, realizing internal serials connection by lead wires. The lead acid battery has the advantages of small volume, light weight and good power characteristic.

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a plate-folded lead-acid battery and a manufacturing method thereof. Background technique [0002] At present, lead-acid batteries with high voltage, small capacity and high power are required in many applications, such as lead-acid batteries used in automobiles. This kind of lead-acid battery adopts the method of vertically placing the plates, and an ultra-short glass is placed between the positive and negative plates. Fiber (AGM) separator, there is an insulating plate between the positive and negative plates and the monomer composed of the AGM separator. The series connection between them is realized by welding the connecting bars, thus forming lead-acid batteries with different voltages and capacities. This storage battery is heavy in weight, large in volume, complex in manufacturing process, many consumables, and high in cost. Contents of the invention [000...
