World's Smallest Battery Created

Posted by Soulskill on from the only-need-fifty-thousand-of-them-to-power-a-phone dept.

Zothecula writes "Because battery technology hasn't developed as quickly as the electronic devices they power, a greater and greater percentage of the volume of these devices is taken up by the batteries needed to keep them running. Now a team of researchers working at the Center for Integrated Nanotechnologies has created the world's smallest battery. 'It consists of a bulk lithium cobalt cathode three millimeters long, an ionic liquid electrolyte, and has as its anode a single tin oxide (Sn02) nanowire 10 nanometers long and 100 nanometers in diameter.' (Abstract in Science.) Although the tiny battery won't be powering next year's mobile phones, it has already provided insights into how batteries work and should enable the development of smaller and more efficient batteries in the future."

    Clearly somebody hasn't seen the designs for the iPhone Femto.

    I'm sure I left them around here somewhere...

    Shit. I vacuumed them up.

      This is all an attempt to capitalize on this week's DVD release of Knight and Day.

      Was that a movie or TV show of some kind? Is that the one with that guy from Valkyrie - the Movie?

      I liked that one. I wonder if they're going to make Valkyrie 2?

      I want my phone to be heavy enough that if I knock somebody down with it, they stay down.

    Scuff your feet and touch it to a doorknob?

    Scientists tell us that the sheer number of "A"s required to describe this battery would fill, like, a bunch of lines.

    Is that the world's smallest battery in your pocket, or are you just happy to see me?

    Yeah but this one powers the worlds smallest electric violin,
    and it's playing the worlds saddest tune today,
    for the worlds second smallest battery..
