Tired of waiting a few hours for your cellphone, tablet, or laptop battery to go from 0 to 100? Batteries of the future may be able to charge in a tiny fraction of the time. Ars Technica dug up a report this week from researchers working on a way to construct batteries that could charge in minutes rather than hours.

The technology is compatible with NiMH and Lithium batteries, with NiMH battery tests showing a battery recharging to 90 percent in ust 20 seconds. It took about 2 minutes to get to the same level with a lithium battery.

Researchers say the technology lends itself to mass production, although it’s too soon to say if or when you’ll be able to get a laptop with a battery that recharges in 2 minutes.

Hit up Ars Technica for a more technical description of the process, or check out the article abstract at Nature.

  1. Ok, let’s see..

    Dell Streak battery, 3.7V, 1530 mAh => 3.7 * 1.53 = 5.66 watt-hours
    75% capacity => 5.66 * .75 = 4.25 watt-hours => 15.3 kilojoules
    deliver in 1 minute => 15.3 / 60 = 255 watts

    I suspect your power brick is going to need to be much bigger, and the wires much thicker…

    Looking at my laptop, it’s got a 10.8V, 5200 mAh battery => 10.8V * 5.2 * .75 * 60 = 2.53 Kwatts…

    Faster charging is useful, but watch out for those extreme predictions..

    1. >the wires much thicker
      I dont think sou, i would use higher voltage and switcht the cells in row to charge…
      And you must not load in 1min may 5min? -> 51Watt its possibel and i would make universal chargers then you need only one charger for laptop ipad iphone.. Sou it can be a little bit bigger.. May 100W at 25V, 4A..
