  •  There are a couple of teams (4+ / 0-)

    that are working on metal-air batteries that supposedly hit 10x the energy density of lithium polymer (which is, frankly, a higher density than I was taught to believe was possible).  One of them just completed a demo for DARPA and collected some government funding, so I'm hopeful that, whatever electric car I buy (and I'm determined to hold on and trade my aging Protege for some EV) I can swap out the batteries in a few years for new ones.

    •  And that's the nice thing about electric motors.. (2+ / 0-)

      As long as they have the voltage they like, they don't care what kind of batteries you use...

      HOWEVER>>>   The problem isn't with swapping out battery packs, it's with controllers.  Different batteries require different cooling flows and the controllers have to know charge/discharge rates.  You HAVE to be able to adapt to this or the batteries won't last.

      So, it is not as simple as just shoving a new battery pack with different cell types under your EV.

      I work with hybrid electric drives, and things are more complex than you might imagine.
