nanowire technology development

3172 2
The battery is of ultra importance to an EV. At Stanford U there is new research in silicon nanowire batteries that GM needs to get involved with. These batteries are supposed to have 10 times the capacity of standard lithium-ion. If this is true it could be the difference between 40 miles and 400 miles. Anyone from Stanford got anything on this? Is it true? This could be a milestone for the Volt!

Last I remember, that Stanford Professor was still running longterm cycling tests to verify the expected long life of this battery through rapid charge / discharge.

He is still contemplating whether to launch a battery company of his own, or to just develop the tech to a point at which he can partner with a company like A123.
