Description
Technical field
The present invention relates to for the direct energy storage device of conversion each other of chemical energy and electric energy, especially for assembling and the hold-down mechanism of large-scale or relatively large redox flow batteries plate.
Background technology
Redox flow batteries is by forming with the separated anode chamber of ionic membrane and cathode chamber, the active electrolyte of the both positive and negative polarity that in battery chamber's cavity, flowing respectively, and their are external anode and catholyte liquid holding vessel respectively, forms closed cycle system.Realize the directly conversion each other of chemical energy and electric energy.
Fig. 1-1 and Fig. 1-2 are a kind of in the existing technical scheme, as can be seen from the figure, conductive separator plate 6 is divided into former and later two electric liquid chambers 5 to element cell in the centre of element cell plate 1, two kinds of electrolyte flow out from top flow export 2 respectively from 7 inflows of bottom inflow entrance, the electric liquid chamber of flowing through.Compress 4, two kinds of electrolyte of ionic membrane between the two element cell plates and between ionic membrane, carry out ionic reaction, electric energy is converted to chemical energy.This reaction is reversible, disconnects external power, and two kinds of electrolyte also can react in battery pile chemical energy is converted to electric energy.Can see that thus bolt hole has 22 among the figure, this structure can only be at cell board less than 0.5 m
2The miniature liquid pile in go up to use, if be used in the large-scale pile not only technology trouble, the more important thing is and cannot say for sure that electric liquid does not leak.
Hence one can see that, and existing cell panel area is less, and general area is less than 0.5 m
2, less because of girth, with several stay bolts or studs tens battery combination are got up, compressed, still can use.Also hold out against with screw thread on the leg of frame of useful flow battery assembling, for example, China Patent No.: 03276099 utility model technical scheme.
But, when the cell panel area greater than 0.5 m
2Perimeter dimension is big, with several bolts tens battery combination, compress, certainly will pitch of bolts strengthen, perhaps must compress with more bolt connection piece, such structure can cause following deficiency: 1, pitch of bolts strengthens or compresses the battery pile flat board with more bolt, is difficult to guarantee even to dull and stereotyped thrust, very likely cause part bolt thrust to lose efficacy the corrosivity solution leakage.
2, bolt passes battery lead plate, and all parts (battery lead plate, barrier film) of battery all need to widen, thereby the formation volume is big and the waste of material.
3, complex structure, loaded down with trivial details, the assembling trouble of technology.The installation and removal inconvenience of battery pack.
4, use 10 screw threads on the leg of frame and hold out against, be difficult to equally to guarantee to dull and stereotyped thrust evenly, very likely cause part bolt thrust to lose efficacy solution leakage.
5, inhomogeneous problem, the leakage problems of the thrust of comprehensive many bolts tension and compression and many screw threads roof pressure limited the total energy density of battery and the raising of power have been done greatly, limited to the cell panel area.
