    I know nuffink about chemistry, but this sounds promising. :)

    That's awesome. I wonder if the battery will lose life rapidly with those quick charge-ups. Either way that is promising news.

    Battery that 'charges in seconds'

    From the BBC

    Sweet and how Ionic :p

    Charging time doesn't seem to be what's crippling Li-Ion batteries now, but the length their charge powers a device. That's where the emphasis needs to be, in perfecting the technology and making more power efficient devices.

    There was something about a new silver battery technology research that may be implemented to greatly lengthen the discharge time.

    Not really. If I can go only 100 miles, but can charge in 10 seconds, that's a trade off I'd be willing to make. Heck, might even make long car trips more pleasant than sitting for 300 miles straight through...

    How long does it take to refill with fuel? 5 minutes tops. Something similar to that timeframe would be more than acceptable to me. (Hours would not be my cup of tea)
    If they implemented a "fast charge" with the current "brake to charge" technology it would be perfect, unless you drove all interstates :D
