What are the advantages of Vanadium Redox Flow Batteries?
- VRFBs have a lifespan of 20+ years
- VRFBs offer immediate energy release
- VRFBs are suitable for grid connection or off-grid settings – ideal for renewable energy
- VRFBs can discharge 100%, without any damage to the battery
- VRFBs are non-flammable
- They ensure power and energy can be scaled independently
- Vanadium electrolyte can be re-used and does not need to be disposed of
- The batteries can be cycled more than once per day
- They use only one element in electrolyte – V2O5
- VRFB energy storage guarantees uninterrupted power supply
How does a Vanadium Redox Flow battery (VRFB) work?
- A flow battery is charged and discharged by a reversible reduction-oxidation reaction between the two liquid vanadium electrolytes of the battery
- Unlike conventional batteries, electrolytes are stored in separated storage tanks, not in the power cell of the battery
- During operation these electrolytes are pumped through a stack of power cells, in which an electrochemical reaction takes place and electricity is produced
