The invention also relates to a redox flow cell stack containing the receiving frame. The cell stack can avoid leakage of electrolytic solution between the flow collection plate and the receiving frame, and in addition, the assembly of the cell stack is simpler.
Description
Technical field
The present invention relates to the flow battery field, relate more specifically to the fit of flow battery.
Background technology
The battery pile of flow battery (for example vanadium oxide reduction flow battery) normally is composed in series by the monocell of some.Each monocell is made of collector body (single collection plate), liquid flow frame, electrode, barrier film, electrode, liquid flow frame, collector body (single collection plate).Fig. 1 shows a stack components figure who is made of two monocells, begins to dress up battery pile according to the der group of end plate 1, pad 2, collector plate (unipolar plate) 3, electrode 4, liquid flow frame 5, barrier film 7, electrode 4, bipolar plates (collector plate) 6, electrode 4, liquid flow frame 5, electrode 4, collector plate (unipolar plate) 3, pad 2 and end plate 1 from inlet.These parts force together by other secure component.When pressing solidly together, as shown in Figure 1, the through hole that is arranged on liquid flow frame 5, unipolar plate 3, bipolar plates 6 upper and lower edges assists to form the electrolyte flow passage, as the electrolyte liquid inlet and outlet of each electrode chamber.
In the prior art, monocell liquid flow frame and collector plate are separated, and between monocell are in addition to adopt face seal, be easy to like this between battery, have leakage between collector plate and liquid flow frame, battery moves for a long time like this, will the performance and the life-span of battery seriously be descended.
Summary of the invention
The present invention aims to provide a kind of sink block that is used for flow battery, there to be the problem of leakage in the solution prior art between collector plate and the sink block.
The sink block that is used for flow battery according to the present invention comprises the body frame, wherein is provided with a slot, is used to insert collector plate; And transplant a cutting, be used to insert the upper end of described slot to realize the sealing of described slot.
In a kind of concrete mode, comprise a slit all around in a side accepting frame, be used for a barrier film being pressed in this side of sink block by a sealing strip.In a kind of optimal way, the sealing bar partly protrudes described sink block when embedding this slit surface, this projection plays the effect of linear sealing between the sink block simultaneously.
In a kind of concrete mode, have slit in two sides of described sink block, be used to embed the sealing strip that carries out linear sealing between the sink block.In an optimal way, one of them sealing strip on each sink block plays simultaneously a barrier film is pressed in effect on the described sink block.
The invention still further relates to the liquid stream battery stack that comprises above-mentioned sink block.
The leakage of electrolyte between collector plate and sink block avoided in design of the present invention.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present invention, constitutes the application's a part, and illustrative examples of the present invention and explanation thereof are used to explain the present invention, do not constitute improper qualification of the present invention.In the accompanying drawings:
Fig. 1 is the exploded view of the liquid stream battery stack of a typical case in the prior art;
Fig. 2 is the schematic diagram of the sink block of a typical case according to the present invention;
Fig. 3 is to use the battery pile part assembly assembly drawing according to sink block of the present invention.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
As shown in Figure 2, sink block comprises body frame 3, wherein is provided with a slot 4, is used to insert collector plate 1.After inserting collector plate 1, cutting 2 is inserted the upper end of slots 4 to realize the sealing of described slot.In order to realize better sealing, can seal with fluid sealant or sealing strip in the joint portion of slot and collector plate (for example bipolar plates).
As shown in Figure 3, electrode material 5 and barrier film 6 are pressed between the sheet frame of collector plate 1 and sink block 3, like this, sink block is all wrapped collector plate and electrode material, has guaranteed battery no leakage between collector plate and sink block.As preferably, be provided with narrow annular slot in a side of sink block, wherein can embed sealing strip, be used for barrier film 6 is pressed on the sink block.
As a kind of substitute mode, also electrode material 5 can be inserted in the slot 4 with collector plate 1.
When assemble is piled, each sink block is forced together, be assembled into whole stack.Adopt linear sealing between frame and the frame.As a kind of preferred mode, can have slit in two sides of sink block, the sealing strip that is used for carrying out linear sealing embeds this slit, and part protrudes in outside the slit.Sealing strip when the position of this slit should make the assembled battery heap on the adjacent reception frame is aligned with each other, to realize means of press seals.As a kind of optimal way, one of them sealing strip on each sink block plays simultaneously barrier film is pressed in effect on the sink block.This mode has solved the leakage between the sheet frame well.
Of the present invention one concrete aspect, this battery pile is a full vanadium cell heap.
In another embodiment, two slots can be set in the part sink block, in two slots, to insert two collector plate respectively.
By setting of the present invention, can avoid the leakage of electrolyte between collector plate and sink block, make also that in addition the assembling of battery pile is comparatively simple.
Be the preferred embodiments of the present invention only below, be not limited to the present invention, for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
