My understanding of the chemistry is that they are using Vanadium Chloride which is not listed in the Wikipedia article. What is mentioned in Wikipedia are membrane cost/stability issues with Bromide. I could imagine the latter is more reactive but I'm definitely not a chemistry buff.
Their view of the chemistry:
> using a molecule developed at the Pacific Northwest National Laboratory.
PNNL’s breakthrough was to introduce hydrochloric acid into the
electrolyte solution,
What I found also newsworthy is that the largest battery soon will be China with 800MWh. That is a typical US nuclear reactor providing power for 1 hour - nothing to sneeze at.
What is also newsworthy is the cost which is also an indication that they got some handle on membrane cost. They are claiming 5cent/kWhr which would be a game changer as it is lower than generating it.
