Description
Technical field
The utility model relates to a kind of lead-acid battery, particularly a kind of battery lead plate of bridge-type lead-acid battery and diaphragm structure.
Background technology
Lead acid accumulator is current of paramount importance secondary chemical sources of electric energy, no matter is on usage quantity or on application range, all at field of power supplies dominate.According to the difference of lead acid accumulator application, startup, igniting, illumination (SLI), industrial, valve-regulated sealed and lead acid storage battery for traction can be divided into.
Dividing plate is the important component part of storage battery, is described as " the 3rd pole " of storage battery.The resistance of dividing plate is the important performance of dividing plate, and it is determined by the tortuous in the thickness of dividing plate, porosity, hole, has material impact to the capacity of storage battery high-multiplying power discharge and terminal voltage level; The stability of dividing plate in sulfuric acid directly affects the life-span of storage battery; The elasticity of dividing plate can delay coming off of positive active material; Clapboard aperture size affects lead dendritic crystal degree of short circuit.Because dividing plate is to the many-sided effect of performances of the lead-acid battery, the raising of every inferior quality of dividing plate development, invariably along with the raising of performance of lead-acid battery.
The traditional dividing plate that current domestic contrast is conventional has rubber separator, AGM dividing plate, PVC dividing plate, PP dividing plate etc.Wherein AGM dividing plate is a kind of new material with superior mechanical, physics, chemical property.Along with being showing improvement or progress day by day of science and technology, and oil, chemical industry, material science development, the application of AGM dividing plate is more and more extensive, has become " the century material, and become main flow dividing plate that battery industry is indispensable.In actual application, because dividing plate long period of soaking is in acid solution, the glass fibre in dividing plate is subject to acid liquid corrosion and ruptures, thus diaphragm structure is gone to pot, the phenomenon such as to subside.In addition, dividing plate, in application process, constantly can suffer mechanical shock, also makes dividing plate easily subside.And once dividing plate starts to subside, the useful life of storage battery greatly can be shortened.
Mandate publication number is that the Chinese utility model patent of CN 202259508 U proposes a kind of AGM baffle of storage battery, and for bag-shaped, be made up of one deck thin glass fiber cotton and one deck raw glass cellucotton, thin glass fiber is cotton inside bag, and raw glass cellucotton is outside bag.It is poor that this AGM dividing plate efficiently solves AGM dividing plate anti-gas impact capacity in prior art, easily produces the problem of dendrite short circuit, thus extend the useful life of storage battery.
Application publication number is that the Chinese invention patent of CN 102891284 A proposes a kind of polar plate of lead acid storage battery, comprise grid, active material, electrode thickness is 0.7 ~ 1.6mm, direct coated AGM smear paper after coating active material, the AGM smear paper thickness used is at 0.1 ~ 0.3mm, aperture is at 8 ~ 15 μm, and porosity is 92% ~ 96%, and specific area is 2 ~ 2.8m
2/ g.This pole plate can directly level stack, and the distortion avoiding pole plate to stand up causing also can effectively prevent from battery from discharge and recharge, producing dendrite short circuit losing efficacy, and extended battery, can also improve high-rate battery discharge ability simultaneously.
Publication number is authorized to be the electrode that the Chinese utility model patent of CN 202797140 U proposes a kind of plumbous carbon composite electrode pole plate and formation thereof.This plumbous carbon composite electrode pole plate comprises dividing plate, the positive plate being arranged on dividing plate both sides Face to face and negative plate, on two pole plates, respectively has a side coating active carbon layer, makes two-plate all have energy storage effect, stored energy capacitance is largely increased.This combination electrode plate, while the electrical property that maintenance is stronger, has good energy-storage property, improves battery capacity, can extend the useful life of battery.
Above three patents have all to a certain degree carried out modification to dividing plate or battery pole plates, thus battery section performance is improved, and extend the useful life of battery to a certain extent, but all fail to solve dividing plate and easily to subside problem.Therefore exploitation dividing plate not easily subsides, long-life lead acid accumulator is the key point of its development.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of bridge-type lead-acid battery battery lead plate and diaphragm structure are provided, this kind of pole plate can make dividing plate whereabouts amount of contraction in vertical direction reduce, and has delayed dividing plate and has subsided and the sedimentation time, the useful life of storage battery is extended.
In order to realize the purpose of this utility model, adopt following technical scheme: a kind of bridge-type lead-acid battery battery lead plate and diaphragm structure, it is characterized in that there is corresponding groove on positive-negative electrode plate surface, be connected by building bridge between battery lead plate with battery lead plate, between AGM dividing plate is placed in battery lead plate and builds bridge, build bridge and upper lower leaf has been carried out to dividing plate.
There is liquid-through hole on described bridge formation surface, and the diameter in hole is 1 ~ 10mm.
The surface density of the surperficial liquid-through hole of described bridge formation is 4 ~ 10/dm
2.
Described bridge formation thickness is 0.1 ~ 1mm.
Described bridge formation spacing is 30 ~ 50mm.
Described plate grooves height is 0.11 ~ 1.1mm, is used for placing building bridge.
