Hi Sean,

  It looks like the energy density for the Vanadium Redox battery isn't that great, perhaps causing some issues for EVs that are weight and space sensitive.  I've recently been researching lithium-ion batteries and ran into these sobering articles about the lack of lithium supply for a world of electric vehicles.  The .PDF paper discusses a possible future with zinc-air batteries.

"new" battery.


"The main advantages of the vanadium redox battery are that it can offer
almost unlimited capacity simply by using larger and larger storage
tanks, it can be left completely discharged for long periods with no
ill effects, it can be recharged simply by replacing the electrolyte if
no power source is available to charge it, and if the electrolytes are
accidentally mixed the battery suffers no permanent damage."

Pretty interesting.

It looks like Subaru may be using this battery in it's "Potential" electric car.  Nothing like a bunch of concepts based on "new" technology. 


Has anyone else heard of this battery?  Is it on the market yet?  I can't find a source for actual purchase of this battery type.  This is just a heads up for you all with potential new tech.
