Description
Technical field
The present invention relates to a kind of two dividing plate pole plate assemblies that mainly can be used for lead acid accumulator.
Background technology
The pole plate assembly of lead acid accumulator is primarily of some positive plates arranged in parallel and negative plate composition, positive and negative pole plate is alternately distributed, dividing plate can be provided with between adjacent both positive and negative polarity, such as glass fibre separator (AbsorptiveGlassMat, be called for short AGM), for valve controlled sealed lead-acid accumulator, electrolyte to be received and is stored in glass fibre separator and pole plate, by the setting of glass fibre separator, the short circuit between positive/negative plate can be prevented, be conducive to reducing volume, be conducive to reducing pole plate vibration, be conducive to realizing lean solution design.
But, along with expansion and the technological progress of range of application, the requirement of pole plate assembly is improved constantly.Such as, for controlling fuel-engined vehicle to the impact of atmospheric environment, electric automobile develops rapidly in recent years, need to increase battery capacity for improving distance travelled, against the background of the prior art, a kind of effective technology path increases quantity of polar plate exactly under certain volume, therefore not only need to add sheet to pole plate is thinning, but also the thickness of AGM dividing plate should be reduced, but in order to avoid short-circuit between plates, under existing the pole plate component structure that AGM dividing plate is set, AGM block board thickness has its lower thickness limit value, the use affecting storage battery can be hindered because of short circuit lower than after lower thickness limit value.And for example, along with the requirement of national energy-saving environmental protection, solar energy photovoltaic system has been listed state key in and has been helped project, wherein supporting with it storage battery is the chief component of photovoltaic system, also be one of whole system life-span minimum composition, the major reason affecting its useful life is exactly in photovoltaic system runs, due to reasons such as weather, battery recycles under being often in low retained storage capacity for a long time, and under low capacity, lead plaster/lead powder isoreactivity material very easily comes off and is distributed in electrolyte, causes battery short circuit or micro-short circuit.
Summary of the invention
In order to overcome the above-mentioned defect of prior art, the invention provides a kind of two dividing plate pole plate assembly, for the pole plate assembly that AGM dividing plate (single dividing plate) is set relative to existing, this pole plate assembly allows the spacing reduced further between AGM thickness and positive/negative plate, quantity of polar plate can be increased further when constancy of volume, improve battery capacity, and be conducive to reducing or avoid to come off the short circuit and micro-short circuit caused because of active material, adopt the battery capacity of this pole plate assembly high, long service life.
The technical solution adopted in the present invention is: a kind of two dividing plate pole plate assemblies being suitable for lead acid accumulator, comprise the some positive plates and negative plate that are parallel to each other, described positive plate and negative plate are alternately distributed, the first dividing plate and second partition is provided with between adjacent positive plate and negative plate, described first dividing plate is can receive and receive formula dividing plate through electrolyte, and described second partition is can through the filtering type dividing plate of electrolyte.
The invention has the beneficial effects as follows: owing to there is positive/negative plate being provided with the second partition of filter capacity and not requiring that second partition receives and stores electrolyte, therefore its thickness can much smaller than the thickness of the first dividing plate (1/10 of such as the first block board thickness), and alleviate the filtering requirement even eliminated the first dividing plate, the thickness of the first dividing plate being reduced to single layer separator structure descends below the lower thickness limit value of the first dividing plate (1/3 of such as this lower thickness limit value) still can ensure that the active material come off from pole plate can not cause short circuit and the micro-short circuit of positive and negative electrode, therefore the gross thickness of the first dividing plate and second partition can be made to be significantly less than the lower thickness limit value of lower first dividing plate of single layer separator structure, saved space may be used for the quantity increasing pole plate, storage battery thus under same volume can have larger capacity, and due to against the background of the prior art, second partition can adopt strainability etc. to be obviously better than the thin-film material of AGM, can more effective and reliably stop that on pole plate, lead powder isoreactivity material is taken off and penetrates in AGM dividing plate, greatly reduce thus, alleviate the short circuit and/or micro-short circuit that even avoid and cause because active material comes off, significantly enhance the useful life of storage battery, according to the contrast experiment of applicant, when being used as energy-storage battery in solar energy photovoltaic system, can make longer cell life 1-3 doubly, life termination, dissect as the complete argillization of lead plaster and grid corrosion fracture cause, do not find short circuit and micro-short circuit phenomenon.The present invention is mainly applicable to lead acid accumulator, also may be used for other similar applications.
