Problems solved by technology

In the traditional lead-acid battery, in the single cell structure, the positive and negative plates are composed of multiple plates. Because this structure determines the complexity of the production process, its production process includes multiple processes, such as casting plate , paste, curing and drying, splitting, welding, etc.; and, since a single cell includes a large number of positive and negative plates, it is easy to cause large lead pollution during its production process; in addition , when the battery is used for the storage battery of an electric vehicle, all batteries placed vertically are used at present, and due to the height restriction, it brings great inconvenience to its installation in the electric vehicle

Embodiment 1

[0031] Embodiment one: if Figure 1-3 As shown, the positive plate 2 and the negative plate 1 of the battery are both made of a single plate, and the positive plate 2 and the negative plate 1 are made of carbon fiber reinforced lead alloy composite materials coated with positive active materials and negative active materials respectively. The plate 2 and the negative plate 1 are respectively provided with a positive tab 8 and a negative tab 5 respectively, and the positive plate 2 and the positive tab 8, the negative plate 1 and the negative tab 5 are respectively integrally punched from carbon fiber reinforced lead alloy composite material. The negative electrode plate 1 and the positive electrode plate 2 are covered by separators 3 and 4 respectively and stacked together. The terminals of this embodiment are drawn from both ends of the battery, according to figure 1 stacked in the same way, that is, the positive tab 8 and the negative tab 6 are on the opposite side, and the...

Embodiment 2

[0033] Embodiment two: see Figure 4 , 5 , the housing 11 of this embodiment has only one end opening, and the positive terminal 9 and the negative terminal 6 are drawn out from this port of the housing 11 . After the negative plate 1 and the positive plate 2 are covered by the separator 3 and the separator 4 respectively, press Figure 4 stacked in the same way, that is, the positive tab 8 and the negative tab 6 are on the same side, and the stacked pole groups follow the figure 2 The way of folding into a single cell, and then put into the housing 11.

[0034] For other content of this embodiment, reference may be made to Embodiment 1.

[0035] Both the positive and negative plates of the battery in the above two embodiments use a single plate. The following describes in detail the embodiment in which one pole, that is, the positive pole or the negative pole uses a single plate electrode, and the other pole uses a plurality of pole plates.

[0036] When a single plate i...

Embodiment 3

[0037] Embodiment three: as Figure 6 , 7 As shown, the negative plate 1 adopts a single plate, and the positive plate 2 is composed of multiple pieces. After the positive plate 2 and the negative plate 1 are covered by the separator 4 and the separator 3 respectively, the multiple positive plates 2 are stacked up and down on the negative electrode. The two surface layers of the plate 1, and finally the negative plate 1 is folded. Of course, the negative electrode plates 1 can also be folded into a stack first, and then a plurality of positive electrode plates 2 are stacked between the folded layers of the negative electrode plates 1 . The folded single cell is finally Figure 7 status shown. Put the folded single cell into the casing 11, such as Figure 10 , 11 As shown, the foldable lead-acid battery includes negative plate 1, positive plate 2, separator 3, negative tab 5, negative terminal 6, negative bus bar 7, positive tab 8, positive terminal 9, positive bus bar 10,...

Abstract

The invention discloses a folding lead-acid storage battery, which comprises a casing, an end cover, a positive plate, a negative plate, a positive lug, a negative lug, a positive terminal, a negative terminal and an electrolyte solution. The casing is provided with at least one end opening, the end opening is packaged by the end cover, at least one of the positive plate and the negative plate is single pole plate, the positive plate and the negative plate are laminated and folded into a single battery cell after respectively coated by a separator, the single battery cell is installed in the casing, the electrolyte solution is poured into the casing, the electrolyte solution is fully attached to the positive plate, the negative plate and the separator, the positive plate and the negative plate are provided with the positive lug and the negative lug respectively, the positive lug and the negative lug are connected with the positive terminal and the negative terminal respectively, and the positive terminal and the negative terminal are led from the end opening of the casing. The folding lead-acid storage battery has the advantages of being novel in structure, large in capacity, high in specific energy, good in vibration resistance performance, good in large-current discharging performance, small in occupied space, low in internal resistance, long in service life, and the like.

Description

technical field [0001] The invention belongs to the technical field of battery manufacturing, in particular to a novel foldable lead-acid storage battery. Background technique [0002] Lead-acid batteries are widely used in many fields such as energy, communication, electric power, transportation and military affairs. In the traditional lead-acid battery, in the single cell structure, the positive and negative plates are composed of multiple plates. Because this structure determines the complexity of the production process, its production process includes multiple processes, such as casting plate , paste, curing and drying, splitting, welding, etc.; and, since a single cell includes a large number of positive and negative plates, it is easy to cause large lead pollution during its production process; in addition , when the battery is used for the storage battery of an electric vehicle, all vertically placed batteries are used at present, and due to the height restriction, i...
