Background technology
Along with scientific and technological development, and the multi-form needs of the mankind to electric energy, people are more and more to the needs of multi-form energy-storage battery.Particularly people are utilizing wind energy, during the regenerative resources such as solar energy, and owing to being subject to the impact of natural conditions, Blast Furnace Top Gas Recovery Turbine Unit (TRT) (as wind-driven generator, solar panel etc.), the electric energy sending is fluctuated, extremely unstable, is difficult to be directly incorporated into electrical network.Various countries research institution is also at the multi-form energy storage method of research and development, and large-scale energy-storage battery, particularly all-vanadium flow battery, cause that capacity is large, the life-span is long, safety, environmental protection, be to be applicable to the high-power desirable energy storage device discharging and recharging, in addition, also can be used for peak clipping Pinggu of electrical network, hotel, hotel, telecommunications, etc. the stand-by power supply of industry.
Existing vanadium cell electrode is a kind of graphite felt of flexibility, when assembling, needs to compress, if too small electrode energy resistance is high for pressure, the electric energy that pressure consumes too greatly on pump is high.And on felt, open runner, and the liquid flowing resistance of runner annex is little, large away from the local liquid flowing resistance of runner, and electrolyte only reacts near runner.
Traditional graphite felt, the mobile of vanadium liquid is by the gap between felt fiber, therefore contact resistance is larger, exists the bad problem of electric conductivity.
Summary of the invention
Thereby the invention provides a kind of three-dimensional netted graphite foam or reticulated vitreous carbon all-vanadium flow battery bipolar plates that can increase the active material utilization of specific area raising battery electrode.
Technical scheme of the present invention is: three-dimensional netted graphite foam or reticulated vitreous carbon all-vanadium flow battery bipolar plates, comprise three-dimensional netted graphite foam or reticulated vitreous carbon (1), it is characterized in that described three-dimensional netted graphite foam or reticulated vitreous carbon (1) have and have the open-celled structure being interconnected, carbon amount is at 10%-100%, a side, bilateral or centre in described three-dimensional netted graphite foam or reticulated vitreous carbon (1) are provided with graphite collector (2), and the carbon content of described graphite collector (2) is 10-100%.

Described bonding mode be gluing or resin-bonding after high-temperature process, treatment temperature is 40-3000C.
In three-dimensional netted graphite foam or reticulated vitreous carbon (1), be provided with training dyke (3), form straight channel in parallel or serpentine flow path.
In three-dimensional netted graphite foam or reticulated vitreous carbon (1), training dyke (3) is set, forms straight channel or the serpentine flow path of series connection.
In three-dimensional netted graphite foam or reticulated vitreous carbon (1), be provided with identical tongue and groove mutually, make effective area increase 1.5 times.
In three-dimensional netted graphite foam or reticulated vitreous carbon (1), be compounded with the material that can improve battery activity and maybe can improve electrode conductivuty and active material, form three-dimensional netted composite material, compound method is dipping, bonding, evaporation, plating, magnetron sputtering or vapour deposition, active with intensifier electrode.
Effect of the present invention is: three-dimensional netted graphite foam or reticulated vitreous carbon all-vanadium flow battery bipolar plates, three-dimensional netted graphite foam or reticulated vitreous carbon have and have the open-celled structure being interconnected, carbon amount is at 10%-100%, a side, bilateral or centre in three-dimensional netted graphite foam or reticulated vitreous carbon are provided with graphite collector, and the carbon content of graphite collector is 10-100%.
The material shape that the present invention mentions is fixed: do not form all-vanadium flow dead angle.Without compression electrodes, effective surface area is large, thereby increases battery volumetric specific energy.
