Abstract
The utility model relates to a storage battery, in particular to a lead-acid battery for double composite polar plate used in the electric bicycle and the emergency light, comprising a positive plate group and a negative plate group, which is characterized in that: the polar group of the monopole negative plate at the two ends of the storage battery forms the double composite polar plate group by the alternative array of groups of double composite positive and negative homopolar polar plates; ultrafine fiberglass baffles are arranged among the double composite homopolar polar plates; the volume of the ultrafine fiberglass baffles is equal with that of the single chip polar plate. Compared with the prior storage battery with common structure, the utility model has the advantages of prolonging the service life nearly one time, having stable discharge and slow descending in the service life, and less deformation of the positive plate, improving the utilization ratio of the negative plate as well as the diffusivity of the electrolyte, greatly prolonging the service life of the storage battery, reducing the use-cost, improving the use value, having obvious technical improvement, active effect and strong practicability compared with the prior art.
Description
Technical field
The utility model relates to storage battery, relates in particular to two compound polar plate lead acid accumulators of using on electric bicycle and the emergency light.
Background technology
At present, because electric bicycle is time saving and energy saving soon than cycling speed, more and more be subjected to consumer's favor.And the driving power of electric bicycle is mainly derived from storage battery.Therefore, the good and bad use effect that directly influences electric bicycle of the performance of storage battery.The lead acid accumulator that uses on the current electric bicycle constitutes one pole pole plate group side by side by the positive and negative pole plate of several monolithics, yet it in use but exists: useful life is short, and positive and negative pole plate distortion is big, and especially negative plate fails to discharge effectively electric energy.Meanwhile, its scope of application also is subjected to certain limitation.
Summary of the invention
It is a kind of under storage battery deep discharge periodic duty condition that main purpose of the present utility model is to provide, suppressed the distortion of positive and negative pole plate to greatest extent, improved the diffusivity of electrolyte, the two compound polar plate lead acid accumulators that prolonged the useful life of storage battery greatly are to overcome the existing deficiency of using storage battery.
For realizing that the technical scheme that the purpose of this utility model adopted is: two compound polar plate lead acid accumulators, be made of positive and negative pole plate group, it is characterized in that: the utmost point group between the one pole negative plate of storage battery two ends is alternately arranged by some groups of two compound positive and negative same polarity pole plates and forms two compound polar plate groups.
Install superfine glass fibre partition board between described two compound plates of similar polarity.
The volume of described superfine glass fibre partition board equates with the volume of monolithic pole plate.
By above technical scheme as can be known, the present invention is under the structural arrangements of excellence, at least embody following superiority: compare with the storage battery of existing ordinary construction, prolong nearly one times its useful life, at life period, discharge capacity is steady, descend slowly, the positive plate distortion is little, has improved the utilance of negative plate, and improved the diffusivity of electrolyte, prolonged the useful life of storage battery greatly.Reduced use cost, improved use value, significant technological progress, positive effect and practical have been arranged than prior art.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
1 one pole negative plate among the figure, 2 pairs of composite negative plates, 3 pairs of anode composite plates, 4 superfine glass fibre partition boards.
Embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
Embodiment: as shown in Figure 1, two compound polar plate lead acid accumulators, the positive and negative electrode group between the storage battery two ends one pole negative plate 1 is alternately arranged by some groups of two homopolarity positive plates 2 and negative plate 3 and forms two compound polar plate groups.And insert superfine glass fibre partition board 4 as a positive pole unit and a negative pole unit between above-mentioned two anode composite plates 2 and two composite negative plate 3, wherein the volume of superfine glass fibre partition board 4 is equal to the volume of monolithic pole plate.
The utility model is applicable to that discharging electric energy on electric bicycle and the emergency light uses.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
Claims (3)
1, a kind of pair of compound polar plate lead acid accumulator is made of positive and negative pole plate group, it is characterized in that: the utmost point group between the one pole negative plate of storage battery two ends is alternately arranged by some groups of two compound positive and negative same polarity pole plates and forms two compound polar plate groups.
2, two compound polar plate lead acid accumulators of using of electric bicycle according to claim 1 is characterized in that: install superfine glass fibre partition board between described two compound plates of similar polarities.
