Description
Technical field
The utility model relates to a kind of electrode of liquid flow cell framework, relates in particular to a kind of all-vanadium flow battery electrode framework.
Background technology
Flow battery, especially vanadium redox battery (abbreviates vanadium cell as, VRB); It is a kind of new and effective big capacity energy-storage battery; Life-span is long, safe, and successful Demonstration Application is smoothly exported in the electric power of wind energy turbine set at present, and is following at wide new energy field; For example wind power generation, photovoltaic generation, intelligent grid or the like all have wide application space.
In vanadium cell; Electrode framework is the important component part of battery; Be different from general secondary cell, the both positive and negative polarity active material of vanadium cell is liquid electrolyte, and its electrolyte is continuous flow regime; This has just determined that needing an airtight space stores electrolyte, has guiding, distributional effects to electrolyte flow simultaneously.
Traditional vanadium flow battery electrode framework electrolyte feed liquor fluid runner is provided with simply, normally by a sprue feed liquor, gets into the shunt conduit of uniform distribution then, the setting of single runner on the one hand, and its hydraulic pressure is higher, and hydraulic pump is had higher performance requirement; On the other hand, simple distribution duct is provided with and often makes the cell reaction district be formed into the reaction dead angle, causes the battery local voltage too high, and then bipolar plates and electrode material are corroded, and has greatly reduced the life-span of battery.Its battery diaphragm directly contacts with electrolyte passage in addition, often because the out-of-flatness of contact-making surface causes the liquid leakage problems that between electrode framework and encapsulant, produces electrolysis.
Summary of the invention
In order to overcome the deficiency of prior art, the utility model provides a kind of electrolyte hydraulic pressure lower, and cell reaction district electrolyte inside flows evenly and the electrode frame of the flow electric current of good seal performance.
The utility model solves the technical scheme that its technical problem adopted:
A kind of electrode frame of flow battery; Comprise framework and inside casing; Be provided with seal groove between said framework and the inside casing; Said inside casing is provided with anodal feed liquor runner, negative pole feed liquor runner, cell reaction district, anodal fluid runner and negative pole fluid runner, and said each electrode solution runner connects the gathering sill of shunting electrolyte respectively; The end of said gathering sill connects the electrolyte passageway; The said passageway other end is an electrolyte distribution; Said distributing trough is provided with the runner of some quantity, and distributing trough links to each other with the cell reaction district; Said gathering sill, passageway and distributing trough top are provided with a baffle.
As the improvement of technique scheme, for further strengthening its sealing effectiveness, said inside casing bottom surface is provided with the bottom surface seal groove of assembling collector.
As the further improvement of technique scheme, for effectively reducing the hydraulic pressure of electrolysis on the flow road, said gathering sill has the end of some quantity, and preferred gathering sill has 2 ends.
The beneficial effect of the utility model is: the utility model has effectively reduced the pressure of electrolyte, thereby has reduced pump pressure through adopting the shunting action of gathering sill, has reduced the pump consumption, has finally improved the energy conversion efficiency of battery; Electrode solution through the synergy of gathering sill and distributing trough, effectively prevents to produce the dead angle in the cell reaction process after getting into the feed liquor runner, has especially improved the electrolyte flow effect of 4 corners in cell reaction district; The setting of gathering sill, passageway and distributing trough top baffle has formed the electrolyte circulation system that seals on the one hand in addition, and the opposing party prevents that battery diaphragm from contacting with the direct of electrolyte passage, has avoided the damage of barrier film, has improved the useful life of battery.
