Paper-Thin Batteries Provide Bendable Power

Posted by CmdrTaco on from the battery-paper-airplanes-please dept.

SkinnyGuy writes "New carbon nanotube-based technology could literally allow companies to paint layers of electricity-holding lithium-ion on standard pieces of paper. The possibilities are endless." You can also read the actual paper.

    What kind of a protocol is hhttp and what kind of a URL is pubsacsorgdoifull101021nn1018158?

    Actual link

      It's much faster than just Hyper, it's Hyper Hyper, which is like regular Hyper except on ADHD. Ooh, look at that blinky ad!

      Yes it's an anecdote! Were you expecting original research in a Slashdot comment?

      It's the new RTFA-test. You're the only one who passed.

    From wikipedia: The specific energy for NiMH material is approximately 70 Wh/kg (250 kJ/kg), compared to 40-60 Wh/kg for the more common nickel-cadmium, or 100-160 Wh/kg for Li-ion.

    This looks like it would be comparable to Li-ion and an improvement over NiMH and NiCd.

    I read the paper and it was Shockingly Powerful.

      I clicked on the link and found that there was no charge. After I read the paper, I found it to be both positive and negative. I found the subject matter to be current and energetic. It was both powerful and enlightning. You seem to be applying some resistance to this where I think you should be looking to reduce your impedance. Of course your position on the matter can help determine your polarity.

      Well, thank god it's Faraday...

    Researchers at Rensselaer Polytechnic Institute produced "paper batteries" on nanocomposite paper with an energy density of about 13Wh/kg back in 2007. You can see the paper here.

    Only if it's a really, really flat and electrically charged, probably for having been hit by a lightning, lion.

    Or a zoo lion run over by a Tesla roadster. Now THAT would be an interesting headline.
