Abstract
The invention discloses an S-shaped electrode plate for starting and stopping a battery. The S-shaped electrode plate is characterized in that the electrode plate is of an external structure in a shape similar to S and comprises a middle S-shaped concave-convex part and straight section parts at the two ends, wherein the upper and lower straight sections of the electrode plate are positioned on the same vertical line, and the upper and lower straight sections are in direct transition with an S-shaped groove; when the electrode plate is assembled, one common tangent parallel to the upper and lower straight sections is available between every two electrode plates, a distance between the two electrode plates is two times of the inner diameter of the S-shaped groove, the inner diameter of the S-shaped groove of the electrode plate is 10-500mm, and the height of the upper and lower straight sections is 3-15mm. A partition board can be fixed by the groove of the electrode plate, so that the drop shrinkage of the partition board in the perpendicular direction is reduced, and the longitudinal stability of the partition board in a wet environment is improved. Besides, the collapse and settling time of the partition board in an acid solution is delayed by the electrode plate, so that the service life of the storage battery is prolonged.
Description
Technical field
The present invention relates to a kind of battery lead plate, particularly a kind of start-stop cell electrode plate with S type groove.
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 object of the invention is to overcome the deficiencies in the prior art, provide a kind of start-stop battery S type battery lead plate, 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 object of the present invention, adopting following technical scheme: a kind of start-stop battery S type battery lead plate, is characterized in that battery lead plate has the appearance structure of similar S word, comprising middle S type jog and the straight part at two ends.
The straight section up and down of described battery lead plate is on same vertical curve.
The internal diameter of the S type groove of described battery lead plate is 10 ~ 500mm.
The straight section height up and down of described battery lead plate is 3 ~ 15mm.
Be direct transition between the straight section up and down of described battery lead plate and S type groove.
Described battery lead plate is when assembling, and have a common tangent paralleled with upper and lower straight section between two two-plates, the spacing between two-plate is the twice of S type groove internal diameter.
Compared with prior art, the present invention has following beneficial effect: dividing plate can be fixed by (1) battery lead plate groove, and dividing plate whereabouts amount of contraction is in vertical direction reduced, and improves its longitudinal stability in wet condition; (2) delay dividing plate subsiding and the sedimentation time in acid solution, thus extend the useful life of storage battery.
