Advantages of all-vanadium redox flow batteries
2022-01-11
Advantages of all vanadium flow batteries:
1. Wide range of applications
It can be used in wind power generation market, national grid peak regulation, new energy electric vehicle power supply, UPS power supply and EpS emergency power supply, power distribution, special batteries, photovoltaic power generation.
2. The design concept is flexible and changeable, with good charging and discharging performance and high electric capacity
The function of vanadium battery is very flexible, and the power and volume can be independently designed. The key to the rated power is the stack, which can be improved by changing the number of cells or the area of the electrodes. The key to the volume is the amount of vanadium ions, which can be constructed according to the volume of the improved electrolyte and the concentration of vanadium ions.
3. The system can be fully automatic equipment closed operation, low-cost manufacturing, green and pollution-free
High adaptability to the natural environment, the battery performance is less affected by the ambient temperature, and when the ambient temperature fully recovers, the battery capacity can also be fully recovered. The system can be fully automatic equipment closed work, and will not cause organic gas and waste electrolyte.
4. Unlike lithium-ion batteries, it is easy to cause explosions and has high safety.
Theoretically high security. Because the active material exists in the electrolyte, it will not cause the change of the object image, and it can be deeply discharged without affecting the battery life. In addition, the reaction process does not cause gas such as H2, there is no risk of explosion, and there is no problem of short-circuit failure.
5. High energy efficiency, high cost performance and long service life
long life. The deep discharge cycle performance is strong, and the capacity is very easy to fully recover after overdischarge, and the ultra-deep discharge does not cause irreversible damage to the battery
