Abstract

The utility model relates to a horizontal bipolar lead-storing battery, which comprises a positive plate, a negative electrode, a gap bridge, a fiberglass partition plate and electrolyte, wherein, the positive plate and the negative electrode are connected into a bipolar electrode plate by the gap bridge. The bipolar electrode plate and the fiberglass partition plate are staggered, accumulated, stacked and assembled into pole groups, a single-polar positive plate and a single-polar negative plate are adopted respectively by terminals, and grids of the single-polar positive plate and the single-polar negative plat are connected with pole ears which are inserted into a busbar and welded. An inner clamping shell is arranged in a housing to clamp the pole groups which are integrally arranged into a U shape, and the U-shaped middle of the pole groups is isolated by a middle plate of an inner shell longitudinally arranged. The utility model has the characteristics of small size, easy installation, the enhancement of sealing and combining efficiency and simple welding of battery terminals.

Description

The horizontal double pole lead accumulator

The utility model relates to a kind of lead accumulator.

Original lead accumulator is made up of positive plate, negative plate, gap bridge, electrolyte etc.Adopt the microscler arrangement of linear pattern between utmost point group, it is big to take volume, and extremely is difficult for installing, and the battery terminal welding is difficult, and deficiencies such as compactness are installed inadequately in lead accumulator inside.

The purpose of this utility model aims to provide little, the easy installation of a kind of volume, has improved sealed composite efficient, and battery terminal is welded simple horizontal double pole lead accumulator.

The purpose of this utility model realizes by following manner.

The utility model comprises positive plate, negative plate, gap bridge, glass fibre separator, electrolyte, connect into double polarity plate by gap bridge between positive plate and the negative plate, the staggered tired folded assembling poling group of double polarity plate and glass fibre separator, terminal then adopts the positive and negative pole plate of unipolarity respectively, the unipolarity plate railings of anode and cathode is connected with lug, lug inserts in the bus-bar and welds, folder shell in being provided with in the enclosure, clamp utmost point group, utmost point group overall alignment becomes the U type, isolates by the inner casing intermediate plate that vertically is provided with in the middle of utmost point group's the U type.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is that the utility model utmost point group U type is arranged vertical view.

Fig. 2 is the utility model left view.

Fig. 3 is that the utility model utmost point group U type is arranged the schematic diagram after launching.

Fig. 4 is the double polarity plate schematic diagram.

Fig. 5 is just (or negative) pole plate schematic diagram of unipolarity.

Shown in accompanying

drawing

1,2,3, the utility model comprises shell 1, interior folder shell 2, positive plate 3, negative plate 4, gap bridge 5, glass fibre separator 6, electrolyte, inner casing intermediate plate 7.Referring to Fig. 4,5 connect into double polarity plate 10 by passing a bridge between positive plate 3 and the negative plate 4, be attached with positive active material 8, negative electrode active material 9 on positive plate 3, the negative plate 4, gap bridge 5 is to scribble the acidproof sealed insulation glue of surging, thereby has solved utmost point group's string lattice short circuit problem.Bipolar plate 10 and glass fibre separator 6 staggered tired folded assembling poling groups 12, the utility model terminal then adopts the positive and negative pole plate of unipolarity (referring to Fig. 5) respectively, unipolarity just (or negative) pole plate outer end is connected with

lug

11,11 of lugs insert in the bus-bar 13 and are welded, compress compacting by high pressure, and by connecting the positive and negative pole that on the bus-bar.Be provided with one and press from both sides shell 2 in shell 1 in projecting inward profile of tooth, clamp utmost point group, utmost point group 12 doubling in interior folder shell 2 is arranged in the U type, isolates by the 2 middle inner casing intermediate plates 7 of folder shell in horizontal the inserting in of vertical setting in the middle of its utmost point group's the U type.

The utility model operation principle is that the horizontal double pole battery is Pb/H ₂SO ₄/ PbO ₂Electrochemical system, its total electrochemical reaction formula is:

The anodal water negative pole of anodal electrolyte negative pole

Active material active material discharging product discharging product

During discharge, its electrochemical reaction process is: the brown lead oxide (PbO in the positive plate ₂) and negative plate in velvet-like lead (Pb), swash (H with the sulfuric acid electrolysis respectively ₂SO ₄) reaction, chemical energy is transformed into electric energy discharges, and generate lead sulfate (PbSO ₄) and water (H ₂O).

During charging, its electrochemical reaction process is: lead sulfate (PbSO on the positive plate ₄) be separately converted to brown lead oxide (PbO ₂) and velvet-like aluminium (Pb), lead sulfate (PbSO ₄) concentration also gradually Zhejiang raise, electric energy changes into chemical energy and stores.

Because it is unipolarity grid by high pressure manufacturing band lug that the utility model has adopted terminal,, solve the difficult problem of terminal welding through the high pressure manufacturing.

Because the utility model is provided with dentation inner casing clamping device, thereby reaches the tight equipment of solution battery, has guaranteed the requirement of antivibration.In addition, U type utmost point group arranges, and utilizes the inner casing intermediate plate to isolate between the two poles of the earth group arranges, and makes the user easier for installation, reduces volume, has avoided the phenomenon of short circuit between utmost point group.

In sum, the utlity model has easy for installation, volume is little, terminal welding is held Easily, long service life, the characteristics such as charging is rapid, charging ability is good.
