All-vanadium redox flow battery energy storage system, referred to as vanadium battery energy storage system. Using the change of the valence state of vanadium ions to realize the storage and release of electric energy, it can be used for large-scale and large-capacity grid energy storage, including cooperation with smart grids, wind and solar power generation, peak shaving and valley filling, and backup power.

The all-vanadium redox flow battery energy storage system is based on the redox reaction of metal vanadium ions and their valence state changes. The all-vanadium redox flow battery can realize charging and discharging, energy storage and release, which is a process that can be nearly infinitely cycled and is safe reliable. Compared with battery energy storage systems such as lead-acid and lithium batteries, the electrolyte of all-vanadium redox flow batteries can be recycled almost 100% when the energy storage project is terminated, which greatly improves the economic benefits and environmental advantages of the project.

Features of Vanadium Batteries

1. Flexible configuration: increasing the number of single cells and electrode area can increase the power of the vanadium battery; increasing the volume of the electrolyte can increase the capacity of the vanadium battery.

2. Long cycle life: cycle times > 8000 times.

3. High safety performance: no danger of explosion and fire.

4. It can be deeply charged and deeply discharged: it can be discharged instantaneously. It only takes 0.02 seconds to switch between charging and discharging states, and the response speed is 1 millisecond.

5. Environmentally friendly: The materials used are all non-toxic materials, and the electrolytes used are liquid vanadium ions. These vanadium electrolytes can be recycled infinitely without causing pollution to the environment.

6. It can meet the production of energy storage battery systems of 1~10MWh, and can be customized according to the special requirements of customers.
