back to article Pret-a-porter: LG boffins' bendy battery can be worn as PANTS

You can shrink them, make them skinny, or make them swallow more charges – but unless you're a Maker Faire type, you can’t actually wear a battery. Until now. Engineering and chemistry boffins working with LG Chem have devised a cable-like lithium-ion battery just a few millimetres in diameter – and flexible enough to be …

      Upvoted. Though I fear that only aficionados of early rock n' roll will get it. :)

    And with an aging population...

    ... and a greater chance of accidental incontinence, this can be lethal!

    One thing left

    Since it's bendy and all, why not just go ahead and build in a recharging system that uses the bending to generate power? That way with the battery around your knee it would recharge while you jog and discharge on the bog for true compute anywhere power.

      I fear having a shit is much more fun than jogging? Sent from my bog

    How well does it cope...

    with an hour in the washing machine at 40C with a dollop of Fairy Non-bio and some Vanish, followed by another hour in the tumble drier on low heat? Or could it perhaps have a special short-circuit option so that it can dry itself by discharging all in one go?

    Warp core breach!

    Ejecting pants in t-minus 5 minutes...4 min 59sec etc

    Perhaps one day we could get a UPS that was just a slightly thicker than normal power cord. A couple CM in diameter, and six feet in length would provide a pretty reasonable volume for the battery itself. I suppose lithium isn't a good choice for a UPS though.

    Maybe you could build an updated version of this into the body shell of a vehicle thus negating the need to have lumps of lead under the sub floor.Though it would need to have an extreemly long shelf life unlike the 5-10 years battery exchange rate on present vehicles.
