[Oeva-list] I was looking at new EVs being developed and I was drawn toward this...

Hi Sean,
 
An interesting chemistry, but its energy density--the amount of energy storable per unit weight--is too low to be of much value for on-road EVs.

"new" battery.

http://en.wikipedia.org/wiki/Vanadium_redox_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.
