Do vanadium batteries degrade over time?
Gavin Loyden:And my understanding is that the vanadium batteries don't suffer from the same sort of degradation from the charging and recharging that other battery systems, particularly solid state battery systems, tend to suffer over time, and VRB can store that energy for quite a long period of time as well. Is that correct?
How long does a vanadium flow battery last?
“One interesting facet of the Vanadium flow battery is that at the end of its life (20 years or even longer), the vanadium electrolyte will have the same value to the steel industry that it has today, and it's easy to recycle — that means that the residual value of the electrolyte is greater than any other battery technology.
