Description
Technical field
The utility model relates to a kind of redox flow batteries, relates in particular to a kind of structure of flat panel configurations type redox flow batteries.
Background technology
Usually redox flow batteries generally adopts a kind of mode of battery unit lamination in upright arrangement being obtained required voltage; Yet; Because the electromotive force of each battery unit of redox flow batteries is lower, preferably adopt the bipolar plates of interlayer in the time of therefore will in each battery unit, letting the electrolyte circulation.
Outbalance is the solution that liquid network and liquid leak in this method.
So-called liquid network is exactly to produce potential difference between inflow or electrolyte that flows out battery unit and other battery unit, therefore makes electric current produce short circuit through electrolyte.
During for example with the series connection of 40 battery units, the lamination just potential difference that produces of section is 1.4 (V) x40 layer=56 (V) ... (1), makes the battery unit of back segment that the electric current of liquid junction of two streams is flowed to leading portion smoothly through this potential difference.
For the interflow Current Control with this liquid adopts in minimum degree the diameter of pipe of transfusion is run business into particular one or done long method, but the shortcoming of these methods is can increase the transfusion resistance of electrolyte circulating pump and cause increasing whole power consumption to increase.
In addition, because the multiple-level stack of battery unit might cause leakage, therefore must adopt termly screw to be increased tight countermeasure.
The utility model content
The utility model provides a kind of flat panel configurations type redox flow batteries, to overcome the above-mentioned defective that prior art exists.
The utility model is to realize through following technical scheme:
A kind of flat panel configurations type redox flow batteries; Comprise electrolysis tank, reaction electrode, current electrode and diffusion barrier; It is characterized in that; Cascade by upside current electrode, upside electrolysis tank, diffusion barrier, downside electrolysis tank and downside current electrode successively from top to bottom; Said electrolysis tank is separated into four tank houses that matrix pattern is arranged by the electrolysis frame, and arranged in a crossed manner in four tank houses of said upside electrolysis tank have two to align reaction electrode and negative reaction electrode, in said downside electrolysis tank, be provided with said upside electrolysis tank relevant position opposite polarity two align, the negative reaction electrode; Each positive and negative reaction electrode contacts with said current electrode respectively, and connects successively according to opposite polarity and to form the loop;
Tank house in the said electrolysis tank is pressed identical polar and is linked to each other through pipeline.The electrolyte stream circulation passage that formation makes electrolyte circulation wherein charge and discharge;
The preferred graphite electrode plate of said current electrode (1,1 ');
Said reaction electrode (4,4 ') adopts chemical property stable and be insoluble to the material of electrolyte, carbon fibre for example, preferred glass fibers reinforced plastics;
The preferred PVC plate of said electrolysis frame (201).
The flat panel configurations type redox flow batteries of the utility model is compared with existing stromatolithic structure battery, has following beneficial effect:
1, through with the ground configuration of battery unit tabular, the quantity that can not increase adhesive surface so just can reduce the possibility of leakage and improve the reliability of battery.
2, make liquid network voltage often rest on 1 battery unit branch through electrolyte is in series flowed in each unit, so just can reduce liquid network electric current.
3, because the thinner thickness of battery unit is tabular, therefore can be arranged on floor or the metope more conveniently, so just increased the degree of freedom that is provided with.
Description of drawings
Fig. 1 is each component configuration figure of the utility model flat panel configurations type redox flow batteries.
Fig. 2 is the structural representation behind each stacking part of the utility model.
Fig. 3 is the sketch map that flows to of the positive and negative electrolysis tank electrolyte inside of the utility model.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to specify the technical scheme of the utility model.
As depicted in figs. 1 and 2, a kind of flat panel configurations type redox flow batteries comprises electrolysis tank, reaction electrode, current electrode and diffusion barrier; It is characterized in that, cascade said electrolysis tank 2 by upside current electrode 1, upside electrolysis tank 2, diffusion barrier 3, downside electrolysis tank 2 ' with downside current electrode 1 ' successively from top to bottom; 2 ' is separated into four tank houses that matrix pattern is arranged by electrolysis frame 201; Arranged in a crossed manner in four tank houses of said upside electrolysis tank 2 have two to align reaction electrode 4 and negative reaction electrode 4 ', in said downside electrolysis tank 2 ', be provided with said upside electrolysis tank 2 relevant positions opposite polarity two align, negative reaction electrode 4,4 '; Each positive and negative reaction electrode 4; 4 ' respectively with 1, the 1 ' contact of said current electrode, and connect successively according to opposite polarity and to form the loop.Embed the seal that seals usefulness on each stromatolith.
Tank house in the said electrolysis tank 2,2 ' is pressed identical polar and is linked to each other through pipeline.The electrolyte stream circulation passage that formation makes electrolyte circulation wherein charge and discharge.The electrolyte stream circulation method is as shown in Figure 3, and anodal electrolyte flows into from anodal liquid inlet 501, flows out from anodal liquid outlet 502 through each positive reaction electrode 4; Negative pole electrolyte flows into from clothes utmost point liquid inlet 503, flows out from negative pole liquid outlet 502 through each negative reaction electrode 4.
Unit cells is disposed on the plane forms plate stromatolithic structure, the polarity of the electromagnetic unit through changing nearside just can be with feed electrode formation tabular, and can reduce the lamination number of element cell.
Conventional battery cells is that series connection lamination and electrolyte are under the situation of circulation side by side; Liquid network voltage becomes voltage according to the number of times of each lamination respectively; For example the second layer is that 1.4 (V) the 3rd layer then is 2.8 (V), and the n layer just produces the voltage of (n-1) x1.4 (V) by that analogy, and this is through the electrolyte circulation short circuit current; Liquid network electric current just, this also is the main cause that causes the battery efficiency difference.The utility model alternatively changes in the formed power-supply battery belfry in the polarity with adjacent element cell, and each electrolyte also flows with polarity, and the electricity of being connected also be certain to from leading portion flow to back one section again to back one section series connection circulation.Liquid network voltage through between such flow unit battery only becomes cell voltage, has therefore just improved electric power storage efficient.
