Description
Affiliated technical field
The utility model relates to a kind of vanadium energy storage device, especially flowable state vanadium energy storage device.
Background art neck
According to the redox characteristic of vanadium ion in electrolyte, people have had the history of two more than ten years to the research of vanadium energy storage device.Vanadium cell is a kind ofly to have the environmental protection of being beneficial to only at the battery of liquid phase generation redox reaction, and the life-span is long, can fill deeply advantage such as to put deeply.The purposes of vanadium cell is very extensive, at large-scale MW class peak load regulation network energy storage device, and the wind power generation energy storage device, the solar power generation energy storage device all has extremely successful example, and the examples of many successful of making stand-by power supply in submarine is also arranged.Because vanadium cell is a flow battery, for amplifying, electrolyte can be opened and leave in separately in the electrolyte tank with the electrode component, is led in the electrode assemblie by channel flow when discharging and recharging, so claim flowable state vanadium energy storage device again.There is following shortcoming in current flowable state vanadium energy storage device: 1, complex structure is fragile; Because be that many group bipolar electrodes are in series, in case wherein one group of damage just can cause total system to damage.2, easy to leak; The flowable state vanadium cell adopts bipolar plate structure more, that is: every pole plate simultaneously is that anodal another side is a negative pole.If adopt pure graphite pole plate,,, very easily cause the both positive and negative polarity solution leakage and cross pollution because graphite always has micropore though resistance is little.If adopt charcoal to mould pole plate, though can reduce seepage, the resistance height.3, general vanadium energy storage device discharges and recharges all and carries out in system, and the charging interval is long.
Summary of the invention
In order to overcome the deficiency of existing energy storage device, the utility model provides a kind of vanadium energy storage device, and this energy storage device can solve the above-mentioned deficiency of traditional energy storage device.
The technical scheme that its technical problem that solves the utility model adopts is: in an insulation crust, there is negative polarity liquid bath-positive polarity liquid bath-negative polarity liquid bath to be arranged in order, it is characterized in that each group both positive and negative polarity electricity of this novel dynamic vanadium energy storage device is to all being unit independently.Each group both positive and negative polarity electricity is to being made up of a positive plate and two negative plates and two barrier films or a negative pole is pulled with two positive plates and two barrier films and formed.Because of being not the bipolar electrode structure, be to mould pole plate with pure graphite pole plate or carbon can not produce positive and negative electrolyte permeability phenomenon, when needing combination, connect a plurality of unit with circuit and get final product.If one of them unit damages, get final product with a new unit replacement, can not cause whole system to damage.The electrolyte replacing velocity of the utility model vanadium energy storage device is fast, and it is standby to do in electrolyte tank to it is characterized in that preparing a large amount of deposit electrolyte outside the vanadium energy storage device, can change the electrolyte tank of having charged during urgent need and get final product, and therefore saves the charging interval.These characteristics make it of many uses, except that general energy storage, more are applicable to vehicle, boats and ships and the required energy storage device of offshore operations platform.This uses novel vanadium energy storage device, is applicable to the multiple electrolyte of distinct methods preparation, comprising: vanadium-sulfuric acid electrolyte, vanadium-electrolysis of hydrochloric acid liquid, vanadium-bromine electrolyte.
