Description

A kind of battery

Technical field

Lead accumulator production technical field is the utility model is related to, more particularly to a kind of battery.

Background technology

Battery is a kind of device that chemical energy is directly translated into electric energy, is the battery designed by rechargeable, passes through Reversible chemical reaction is realized and recharged, and typically refers to lead-acid accumulator, it is one kind in battery, belongs to secondary cell.It Operation principle：Internal active material is regenerated using the electric energy of outside during charging, is chemical energy, it is necessary to discharge electrical power storage Chemical energy is converted to electric energy output by Shi Zaici.

At present, common battery is typically respectively placed in the townhouse formula battery case at interval by 6 pole groups and combined, connection Row's formula battery case includes cell body and separates the demarcation strip in cell body space, and cell body is separated into 1 × 6 or 2 × 3 list by demarcation strip Lattice, each single lattice is interior to place a pole group.Single pole group is sequentially overlapped by positive plate, dividing plate and negative plate to be formed in parallel；Just Lug is respectively equipped with pole plate and negative plate, the lug of same sex pole plate is connected by welding manner and connects pole and formed and is confluxed Row.Using the end pole positioned at both ends positive terminal and negative terminal as whole battery, remaining pole passes through lead mistake respectively Bridge is positive and negative alternately to be connected, and all 6 pole groups is cascaded, connecting positive and negative pole respectively by wire can be to electric power storage Pond carries out discharge and recharge.It is that two positive negative bus for needing lead gap bridge connection are directly extended into phase also to have some batteries at present Even, to avoid the use that lead is passed a bridge, so as to avoid the generation of related defects at conventional lead gap bridge.

Such as the Chinese utility model patent that Authorization Notice No. is CN203415642U disclose it is positive and negative between a kind of pole group Bus-bar is directly connected without bridge lead-acid accumulator, including：Pole group, battery container, leading-out terminal, bus-bar, groove, conflux Row is connected in series point, grid, neck, and the battery container is provided with some pole groups, and being provided with both positive and negative polarity between the group of pole draws Terminal, bus-bar, the bus-bar top are provided with groove, and the bus-bar place of being connected in series is connected in series point provided with bus-bar, confluxed Row is connected in series a little, and grid, neck are provided with inside the battery container.

But in the prior art, each pole group respectively has a positive and negative bus-bar, positive negative bus series connection between the group of pole, I.e. both junctions share two bus-bars, and materials'use amount is more.

Utility model content

The utility model is in view of the shortcomings of the prior art, there is provided the battery that a kind of lead usage amount is more saved.

A kind of battery, including battery case, the battery case is interior to be provided with some demarcation strips, and its inner chamber is separated into six is in The single lattice of word order, each single lattice are filled with pole group, the pole group by positive plate, negative plate and between dividing plate form, With having all positive plates and all of connecting respectively on anode ear, negative plate with negative electrode lug, on each pole group on positive plate The positive bus and negative bus-bar of negative plate, the vertical single lattice orientation of the positive bus, negative bus-bar are set, Two neighboring pole group is connected by sharing a bus-bar, and the shared bus-bar is across on demarcation strip.

For the battery for the single lattice for being separated into 1 × 6, by prior art, 6 pole groups in requisition for 12 to confluxing Row.And in the utility model design, except each 1 bus-bar at both ends, middle adjacent positive/negative plate shares a bus-bar, this Sample, on the one hand eliminate gap bridge and connect this structure, avoid gap bridge coupling part and defect occur and cause battery defect, it is another Aspect also saves bus-bar usage quantity, saves lead dosage.

Preferably, the thickness of the anode ear is more than the thickness of negative electrode lug.It is furthermore preferred that the anode ear thickness is 2.0 ~3.0mm, negative electrode lug thickness are 1.0~2.0mm.Most preferably, the anode ear thickness is 2.5mm, and negative electrode lug thickness is 1.5mm。

Preferably, the gap between positive and negative pole plate is 2.2mm.

Preferably, the bus-bar thickness is 7~9mm.

The utility model battery sets positive bus, the vertical single lattice orientation of negative bus-bar, two neighboring Pole group is connected by sharing bus-bar, and the shared bus-bar is across on demarcation strip, so as on the one hand eliminate gap bridge This structure is connected, gap bridge coupling part is avoided and defect occurs and cause battery defect, on the other hand also save bus-bar Usage quantity, save lead dosage.

Embodiment

As shown in Figures 1 to 3, a kind of battery, including battery case 1, battery case 1 is interior to be provided with 5 demarcation strips, by its inner chamber point Six inline single lattices 3 are divided into, each single lattice 3 is filled with a pole group 4.Pole group 4 is by positive plate 5, the and of negative plate 6 Dividing plate 7 between the two forms, and the gap between positive plate 5 and negative plate 6 is 2.2mm, have on positive plate 5 anode ear 11, There is negative electrode lug 12 on negative plate 6.The positive pole on each pole group 4 with connect respectively all positive plates 5 and all negative plates 6 converges Stream row and negative bus-bar, the vertical orientation of single lattice 3 of positive bus, negative bus-bar are set, and two neighboring pole group 4 passes through A bus-bar series connection is shared, across on demarcation strip 2, the positive bus 8 and negative pole at both ends converge the shared bus-bar 10 Stream row 9 is then connected to positive and negative end pole.All bus-bars, including shared bus-bar 10 and the positive bus 8 at both ends With negative bus-bar 9, thickness is 7~9mm.

The thickness of anode ear 11 is 2.0~3.0mm, and the thickness of negative electrode lug 12 is 1.0~2.0mm.In one embodiment, The thickness of anode ear 11 is 2.5mm, and the thickness of negative electrode lug 12 is 1.5mm.

For the battery of single lattice 3 for being separated into 1 × 6, by prior art, 64 couples in requisition for 12 of pole groups are confluxed Row.And in the utility model embodiment, except each 1 bus-bar (positive bus 8 and negative bus-bar at both ends at both ends 9), middle adjacent positive plate 5, negative plate 6 have shared bus-bar 10, so, on the one hand eliminate gap bridge and connect this knot Structure, avoid gap bridge coupling part and defect occur and cause battery defect, on the other hand also save bus-bar usage quantity, save Save lead dosage.
