Abstract
The invention provides a folding type pole group of a lead-acid storage battery, relating to the field of the lead-acid storage battery. The folding type pole group consists of a positive plate, a negative plate and a diaphragm which are combined into an S shape and folded into a pole group. The folding type pole group provided by the invention has the advantages that the problem of bad consistency of all the pole plates in the traditional pole group is effectively solved; when the assembled battery is charged and discharged, the distribution of internal current is uniform, the application range of the thickness of the pole plates is wide and the large-current discharging performance of the storage battery can be effectively improved.
Description
Technical field
The present invention relates to a kind of collapsible utmost point group of lead acid accumulator, belong to the lead acid accumulator field.
Background technology
Along with science and technology and epoch are progressive, people more and more pay attention to environmental problem and energy problem, and diversified, complicated trend appears in the storage battery environment for use, and battery has been proposed new challenge in reliability and aspect of performance.
Present existing lead acid accumulator pole group production method mainly contains two kinds: a kind of is flat pole plate, by negative plate-barrier film-positive plate-barrier film-negative plate ... the compound mode of barrier film-positive plate-barrier film-negative plate composes in parallel utmost point group, because this kind utmost point group's quantity of polar plate is more, the distributivity of electric current is relatively poor, generally through after 5 cycle charge-discharges, brown lead oxide (active material) content of inner each positive plate of utmost point group differs larger, has affected the performance of battery.Another kind is takeup type utmost point group, namely according to the combination of negative plate-barrier film-positive plate-barrier film by helical structure coiling poling group, such utmost point group is very strict to the thickness requirement of pole plate, electrode thickness requires below 1.5mm.
Summary of the invention
The object of the invention is to overcome the weak point of existing lead acid accumulator pole group structure, provide among a kind of utmost point group the inner active material of positive plate to be evenly distributed, internal current is evenly distributed, and to the collapsible utmost point group of electrode thickness lead acid accumulator applied widely.
Technical scheme of the present invention is: the collapsible utmost point group of lead acid accumulator, consisted of by positive plate, negative plate and the barrier film that is clipped in therebetween, its improvements are that described positive plate, negative plate and barrier film respectively have a slice, press the positive plate-barrier film-folding composition of the negative plate combination rear S of one-tenth shape utmost point group.
Each foldable layer is adjacent to mutually among this utmost point group, and the folding crutch crook flushes.
Collapsible utmost point group provided by the invention, because positive and negative pole plate and barrier film respectively are a slice, active material is coated in on a slice grid, during battery charging and discharging, internal current is evenly distributed, after repeatedly circulating, the inner brown lead oxide active material of positive plate still is evenly distributed, thus the Effective Raise battery performance.And this utmost point group is applied widely to electrode thickness, can make the battery of all size.
Description of drawings
Accompanying drawing is structural representation of the present invention.
Embodiment
The below further specifies the present invention take 100Ah utmost point group as example.
Referring to accompanying drawing, positive plate 1 thickness 3.1mm, width 150mm, length 850mm; Negative plate 2 thickness are 1.8mm, width 150mm, length 1020mm; Barrier film 3 thickness are 1.5mm, width 160mm, length is 1025mm, press S shape folding after just very 5 layers, negative pole is 6 layers, is middlely separated by the AGM barrier film, consists of utmost point group.Utmost point group is assembled into carries out 30 fast charging and dischargings circulations behind the battery, after circulation finishes battery is dissected and positive plate is launched, the brown lead oxide content of four jiaos on pole plate of test and intermediate point, concrete numerical value is as follows:
Test data shows that the inner brown lead oxide of positive plate is evenly distributed.
Claims (2)
1. the collapsible utmost point group of a lead acid accumulator is made of positive plate, negative plate and the barrier film that is clipped in therebetween, it is characterized in that described positive plate, negative plate and barrier film respectively have a slice, presses to become that S shape is folding to form utmost point group after positive plate-barrier film-negative plate combination.
2. the collapsible utmost point group of lead acid accumulator according to claim 1, it is characterized in that: each foldable layer is adjacent to mutually among this utmost point group, and the folding crutch crook flushes.
