Advantages of vanadium redox battery

1. What are the advantages of vanadium redox battery?
Non degradation, non-flammable, low likelihood of fire:
The Vanadium Redox Flow Battery stands out from other batteries due to the favourable characteristics of the vanadium electrolyte (‘electrolyte’), which is used as a solution in both tanks of the battery. The use of the same solution alleviates the possibility of cross-contamination of the electrolyte, therefore eliminating degradation.
Over 50% of the electrolyte solution is made up of water, which gives the electrolyte a non-flammable property. In the event of short circuiting, intense heat or high pressure, it is unlikely for the battery to catch fire.
Whilst some heat may be discharged from the battery, it will not be at a level that is deemed unsafe.
2. Can vanadium electrolyte be recycled?
As is with any development, the Vanadium Redox Battery has faced misconceptions around its cost. The price of vanadium electrolyte is highly dependent on vanadium market prices. However, the electrolyte can be re-used ad infinitum, and the vanadium in the electrolyte can be recovered and re-used in a myriad of other applications including as a strengthening alloy for steel. These re-use and recovery options have led to market participants to begin leasing the electrolyte to help manage cost considerations.
