Thinking about this a bit more, this is what is required by Lithium battery producers.

But then you have to design and prove a process flow, permit & site a chemical refinery in order to produce the Precursor active materials for these batteries.
That's before you build the gigafactory to produce the batteries.
I built a website a while back & one of the graphics I had someone produce showed the materials required in a Lithium Ion battery.

I think Vanitec should consider putting together a material comparison like the above as instead of Lithium, Nickel, Graphite, Silicon, Cobalt, Salt for the Anode & Cathode sides of Lithium Ion Batteries, Show what Vanadium batteries need.

Vanadium Pentoxide & some readily available reagents, acids? The balance of plant in plastic, steel, GRP, all readily available.

One commodity vs 5 or 6?

We need large scale financing of long life infrastructure which is what I see Vanadium Redox Flow batteries as. (I think the virtually inexhaustible deposit at Speewah fits within this multi-decade VRFB idea).

OK Better do some work now.
