Description
Technical field
The present invention relates to a kind of application of battery performance restoration methods in zinc-bromine flow battery.
Background technique
The renewable energy such as wind energy, solar energy have the characteristics that discontinuous, unstable, this characteristic can make it grid-connected
In the process power grid is caused to impact, influences power network safety operation.Energy storage technology then can guarantee renewable energy power generation simultaneously
The efficient stable of net is run.Energy storage technology is broadly divided into physics energy storage and chemical energy storage two major classes.It is suitable in chemical energy storage big
Scale, large capacity energy storage redox flow batteries because of its, response mutually indepedent with the power of battery and capacity rapidly, structure
Simply, the advantages that easily designed and receive significant attention.The one kind of zinc-bromine flow battery as redox flow batteries, except tool
Have outside above-mentioned advantage, also there is high open circuit voltage (1.85V), high theoretical energy density (435Wh/Kg), electrolyte, diaphragm price
Cheap equal many advantages.These advantages also make it more competitive compared with other flow batteries.Zinc-bromine flow battery is in charge and discharge
There are problems that the accumulation of cathode zinc during electricity operation, and the accumulation of zinc can make battery polarization become larger battery performance is caused to decline
Subtract, influences battery, even will form dendrite under serious conditions and battery short circuit is caused to fail.Therefore, cathode zinc is solved
Accumulation problem to improve battery, ensure battery stable operation play a significant role.
Summary of the invention:
Present invention aims at solving the above problems, the method for zinc-bromine flow battery battery performance recovery is provided, is passed through
Positive and negative anodes electrolyte, which mutually mixes, makes the zinc of accumulation directly react generation zinc bromide with bromine, to make electricity in cell performance decay
Pond performance is restored, and battery purpose is improved.
To achieve the above object, the technical solution adopted by the present invention are as follows:
A kind of restoration methods of zinc bromine single flow battery performance, the anode chamber of battery is interior to be filled with anode electrolyte, storage
The electrolyte liquid being stored in cathode storage tank circulates between cathode storage tank and the cathode chamber of battery by the road, transports in battery
After row a period of time, the anode electrolyte in anode chamber is imported in cathode storage tank and is mixed with electrolyte liquid, then by portion
Mixed liquor is divided to be again filled in anode chamber, mutually mixing by positive and negative anodes electrolyte restores battery performance.
Battery operation for a period of time after, when energy content of battery efficiency decay 5%-10% when, carry out positive and negative anodes electrolyte mutually mix.
Battery operation for a period of time after, by anode chamber, cathode storage tank is connected by the road, make in cathode storage tank in
Electrolyte circulates between cathode storage tank and the anode chamber of battery, and mutually being mixed by positive and negative anodes electrolyte keeps battery performance extensive
Multiple, mutually mixed cut-off condition is that battery open circuit voltage drops to 0V.
Anode electrolyte and electrolyte liquid using the identical electrolyte of composition as zinc-bromine flow battery.
Beneficial outcomes of the invention:
The present invention proposes battery performance restoration methods when a kind of zinc-bromine flow battery performance degradation, solves zinc-bromine flow battery
Efficiency attenuation problem in operational process improves battery.
Detailed description of the invention
Fig. 1 is mutually to mix battery operation situation with electrolyte in operational process
Fig. 2 is not carry out electrolyte in operational process mutually to mix battery operation situation
Specific embodiment
The following examples are not intended to limit the scope of the invention to further explanation of the invention.
Embodiment 1
With 2MZnBr2+ 3MKCl+0.4MMEP is that electrolyte carries out the experiment of zinc-bromine flow battery cycle performance, and electrode is carbon
Felt, electrolyte flow rate 60ml/min, current density 40mA/cm2.Electrolyte is carried out when energy content of battery efficiency decays mutually to mix.It is real
Test as a result, it has been found that, battery operation 220 recycle, the energy content of battery efficiency decaying 8%, positive and negative anodes electrolyte is mutually mixed, until battery
Open-circuit voltage is 0V, is continued to battery charging and discharging, battery performance is restored to initial level.
Comparative example
With 2MZnBr2+ 3MKCl+0.4MMEP is that electrolyte carries out the experiment of zinc-bromine flow battery cycle performance, and electrode is carbon
Felt, electrolyte flow rate 60ml/min, current density 40mA/cm2.Energy content of battery efficiency does not carry out electrolyte when decaying and mutually mixes.
Experimental result discovery, does not carry out electrolyte and mutually mixes, and with the increase of recurring number, the decaying of energy content of battery efficiency gradually aggravates.
