Embodiment Construction

[0028] as attached figure 1 As shown, the bipolar plate 2 is folded in half at the lead wire, and a total of 11 pieces are folded; the U-shaped bipolar plate 2 is vertically placed inside the unipolar plate 1a, and the opposite polarity side is adjacent to the unipolar plate, and the bipolar plates are placed in sequence. A total of 11 bipolar plates 2 are stacked to ensure that the polarities are staggered, and a unipolar plate 1b with opposite polarity is placed outside the last bipolar plate; the separator is cut into a separator 3 that is 2.1 times the area of ​​the side surface of the unipolar plate 1 , cutting a total of 24 pieces, and then folding them into a V shape to surround the aforementioned 24 polar plates respectively; cutting the insulating plastic film into 24 film sheets slightly larger than the area of ​​the side surface of the unipolar plate 1, and pasting these films on the unipolar plate 1 respectively. The outer surface of the outer side of the polar pla...

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...
