Description
Technical field
The utility model belongs to lead-acid accumulator field, and sheath copper bus-bar is based on more particularly to a kind of lead-acid accumulator
Pole group.
Background technology
With the fast development of national economy and non-renewable, the green energy resource that country will promote the well-being of mankind of fossil resource
The project of giving priority to is classified as, establishs and enforces PM2.5 discharge standard, the electric car splendid prospects of " zero " discharge, obtains the world
The electric tool such as the favor of various countries, the electric bicycle of the suitable for China spontaneously formed at home, low-speed cars continues to develop strong
Greatly, battery 95% used in its market is above is cost performance highest lead-acid battery, its electrode are exactly monopole ear slice structure, although
The market demand can be met, but more problems be present, such as：High-rate performance is poor, particularly continuation heavy-current discharge, mainly
Embodiment is to be short of power；Cryogenic property is poor；Capacity attenuation is too fast；Battery fast charging and discharging scarce capacity, particularly Large Copacity
Battery；Stability is not high with uniformity.
And existing current lug is generally located on top, electrode is from top to bottom apart from more and more remote, active material utilization
Gradient be present, active material utilization gradually reduces, and the low position active material of utilization rate is also easy to produce sulfation, causes the life-span
Shorten, electrode discharge and recharge from top to bottom, CURRENT DISTRIBUTION is uneven, and the active material away from lug position is not easy full charging or electric discharge
Not exclusively, and monopole ear electric current input and output effect is poor, particularly low temperature and high current.
Utility model content
The purpose of this utility model is：For overcome the deficiencies in the prior art, there is provided a kind of battery combination property is high, circulation
Pole group of the lead-acid accumulator based on sheath copper bus-bar of service life length.
To achieve the above object, the technical solution of the utility model is：
A kind of pole group of lead-acid accumulator based on sheath copper bus-bar, including two sheath copper bus-bars, each remittance
Stream row is provided with least three row's grooves, and the top of bus-bar is provided with connecting hole, and positive plate wherein side is provided with corresponding with groove
Lug, negative plate wherein side is provided with the lug corresponding with groove, and positive plate intersects with negative plate to be stacked, two bus-bars
Groove is placed in the pole plate both sides being stacked in opposite directions, and the lug of positive plate welds with side bus-bar groove, and the lug of negative plate is equal
Welded with opposite side bus-bar groove.
Further, copper-clad lead bus-bar is using plating or gravity casting.
Further, using 3~5 row's grooves.
Further, the bus-bar can use sheath silver, sheath iron or sheath constructed of aluminium.
As a result of such scheme, the beneficial effects of the utility model are：
1st, the lug that the utility model uses is arranged on the side of pole plate, and uses multipole ear structure, electric current export resistance
Power is lower, and the active material utilization on electrode is higher and evenly, effectively solves electrolyte stratification and produce sulfate to cause
Discharge and recharge is difficult；
2nd, the sheath copper bus-bar used, bus-bar are arranged on the side of pole group, submerge in the electrolytic solution, the resistivity of copper
Less than the resistivity of lead, electric conductivity is more excellent, reduce the internal resistance of cell, battery performance General Promotion, but copper just easily by
Oxidation dissolution, life cycle shorten, and lead is most erosion-resisting, therefore molten to protect copper not occur or postpone generation in the electrolytic solution
Solution and in one layer of lead of its Surface coating；
3rd, the utility model electrode charge and discharge is uniform, improves stability and uniformity, and high current charge-discharge ability is obvious
Improve, cryogenic property significantly improves, and extends the service life of battery.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of bus-bar in the utility model.
Reference：1- bus-bars, 2- grooves, 3- connecting holes, 4- negative plates, 5- positive plates, 6- lugs.
Embodiment
Embodiment：With reference to Fig. 1, Fig. 2, a kind of pole group of lead-acid accumulator based on sheath copper bus-bar, including two sheaths
Copper bus-bar 1, the bus-bar 1 of pure lead and metal is replaced using the bus-bar 1 of sheath copper, reduces internal resistance, electric conductivity carries
Height, and anticorrosive increase, each bus-bar 1 are provided with least three row's grooves 2, groove 2 and pole plate side on bus-bar 1
The number of lug 6 set as needed, the top of bus-bar 1 is provided with connecting hole 3, the wherein side of positive plate 5 be provided with
The corresponding lug 6 of groove 2, the wherein side of negative plate 4 are provided with the lug 6 corresponding with groove 2, electrode active material utilization rate
Height, uniformly, stability are improved with uniformity, and positive plate 5 intersects with negative plate 4 to be stacked, and two grooves 2 of bus-bar 1 are placed in opposite directions
The pole plate both sides being stacked, the lug 6 of positive plate 5, which is inserted in the groove 2 of side bus-bar 1, to be welded, and the lug 6 of negative plate 4 is equal
Insert in the groove 2 of opposite side bus-bar 1 and weld.
Copper-clad lead bus-bar 1 is using plating or gravity casting, time short efficiency high, the adhesion of copper-lead in the present embodiment
By force.
3~5 row's grooves 2 are used in the present embodiment.
Bus-bar 1 described in the present embodiment can use sheath silver, sheath iron or sheath constructed of aluminium, simply sheath silver into
This is far above sheath copper, and the electric conductivity of sheath iron and sheath aluminium is not so good as copper, considers sheath copper most from cost and performance synthesis
It is good.
