I'm firmly of the camp that says "I'll believe it when I see it", but if true this does present a rather interesting potential to advance solar and wind power by making it cheaper over the long haul to go that route. :) Of course, a well maintained set of lead acids will do 30+ years if you don't play the fool or be an idiot with them. But hey, not everyone wants to futz with weekly battery maintenance either. So I say, bring on the uber maintenance free batteries, which will in turn attrack the uber lazy. :P

    1100 wH/kg is pretty hefty claim. The article says 4x better then current tech, but I would say that is more the 5x the best LiCo batteries.

    Next question is safety with that energy density. Hope they don't lose the anti-matter containment field.

    Almost 40x times more than my batteries. One 30 kg battery would be all I need.

    Gotcha!
    The article says that the new batteries have four time the power density of conventional, i.e. lower internal resistance. Not higher energy density.
    1100 Watt/kg not Watt-hour/kg.

    Either they have found a better way to reduce the resistive losses per unit area in the electrode structures or get higher current density per active surface of plates. Or both.
    But the energy density in terms of chemical energy per unit of plates/active material/electrolyte/separator mass does not appear to be greatly different.

    Or the reporter didn't know the difference between W and Wh.

    And they got more than a 10x improvement in energy density? Not likely. The usage of W and power is consistent.

    Perhaps you're right. Too bad. I won't be able to get away with one 30 kg battery :cry:

    Got a really good deal on a surplus battery from Boeing? Only lightly used.
