Abstract
The invention discloses a composite polar plate of a storage battery. The composite polar plate of the storage battery comprises a base flat plate and active cover plates, wherein the active cover plates are respectively arranged on the front surface and the back surface of the base flat plate; each active cover plate comprises a metal wire mesh and an active substance filler; the metal wire meshes are impregnated and cured in the active substance fillers; the active cover plates are in square flat plate structures; the metal wire meshes are in three-dimensional network structures formed by weaving lead alloy wires. In the mode, according to the composite polar plate of the storage battery disclosed by the invention, a three-layer composite structure is adopted, and the active substance filler is locked by the active cover plates on the surfaces firmly, so that the active substance filler does not fall easily, the service life of the polar plate is prolonged, and the work efficiency of the storage battery is guaranteed effectively.
Description
Technical field
The present invention relates to accumulator plate design field, particularly relate to a kind of storage battery compound polar plate.
Background technology
Electric bicycle is ridden conveniently, and zero discharge is pollution-free to air, and good energy saving property, is deeply subject to the welcome in market, and sales volume is all increasing every year.In the composition of electric bicycle, the shared cost of storage battery is higher, and storage battery is running stores, and general electric bicycle is using two to the obvious decline that there will be course continuation mileage after triennium, the storage battery that need to more renew.
Present electric bicycle is of a great variety, but most what use is all lead acid accumulator, because the high-quality high price of the lithium battery of comparing, and lead acid accumulator with low cost, cost performance is high.Lead acid accumulator relies on the chemical reaction of pole plate and electrolyte to realize and discharges and recharges and energy storage, pole plate is its critical piece, but the active material on pole plate easily comes off and decomposes in electrolyte in long-term use procedure, the active material constantly reducing has affected the performance and used life of storage battery, reduce course continuation mileage, increased the later maintenance use cost of electric bicycle.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of storage battery compound polar plate, composite construction, active material difficult drop-off, the long service life of pole plate.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of storage battery compound polar plate is provided, comprise: base plate and active overlay, described active overlay is separately positioned on the front and back of base plate, described active overlay comprises respectively woven wire and active material filler, described woven wire dipping is solidificated in active material filler, the described active overlay outward appearance slab construction that is square, described woven wire is to weave by lead alloy silk thread the dimensional network structure forming.
In a preferred embodiment of the present invention, described active material filler is brown lead oxide or pure lead.
In a preferred embodiment of the present invention, described woven wire is separately fixed at the front and back of base plate.
In a preferred embodiment of the present invention, described active overlay is symmetricly set on respectively the front and back of base plate.
In a preferred embodiment of the present invention, described base plate is to cast by lead alloy the flat board forming.
The invention has the beneficial effects as follows: a kind of storage battery compound polar plate that the present invention points out, adopt three-layer composite structure, the active overlay on surface firmly pins active material filler, difficult drop-off in use procedure, extend the useful life of pole plate, effectively ensured the operating efficiency of storage battery.
Brief description of the drawings
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:
Fig. 1 is the structural representation of a kind of storage battery compound polar plate one preferred embodiment of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, base plate, 2, active overlay, 3, woven wire.
Embodiment
To the technical scheme in the embodiment of the present invention be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of storage battery compound polar plate, comprise: base plate 1 and active overlay 2, described active overlay 2 is separately positioned on the front and back of base plate 1, described active overlay 2 comprises respectively woven wire and active material filler, described woven wire dipping is solidificated in active material filler, the described active overlay 2 outward appearances slab construction that is square, described woven wire 3 is to weave by lead alloy silk thread the dimensional network structure forming, under the network support of woven wire 3, although the active material filler after solidifying is large with extraneous contact area, but structural strength is high, difficult drop-off.
A kind of storage battery compound polar plate of the present invention can be made respectively positive plate and negative plate, described active material filler is brown lead oxide or pure lead, what active material filler selected that brown lead oxide makes is positive plate, and what active material filler selected that pure lead makes is negative plate.
Further, described woven wire is separately fixed at the front and back of base plate 1, and structural integrity is good, effectively prevents coming off of active overlay 2 entirety.
Further, described active overlay 2 is symmetricly set on respectively the front and back of base plate 1, and in use procedure, symmetry is good, stable performance.
Further, described base plate 1 is to cast by lead alloy the flat board forming, good conductivity, and intensity is high, and sludge proof performance is good.
In sum, a kind of storage battery compound polar plate that the present invention points out, compared with common pole plate, the active material filler difficult drop-off on surface, the long service life of pole plate, transformation efficiency is high, and the storage battery cost performance of making is high.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
