[Oeva-list] MIT research: Lithium Iron Phosphate batteries

[Philip Kollas]

Did anyone else hear the NPR Science Friday broadcast on 3-13-09, in which
an MIT professor of materials & engineering talked about their discovery?
He said they had found that tweaking lithium with iron phosphate (iron
phosphate being the same material that battery giant BYD is now going with
for their rechargeable cars) made for a much-quicker recharge time as well
as greater acceleration.  The recharge time went from hours down to about a
minute.

If this is true and the new material can be incorporated into an affordable
technology for EV batteries, it seems we would have overcome one of the
common objections to EVs (lengthy recharge time).

Thanks, Philip Kollas
