A Non-Toxic, Paper Battery / Supercapacitor

Posted by kdawson on from the i'll-take-a-ream dept.

jcr writes "Researchers at Rensselaer Polytechnic Institute have developed a combination battery/capacitor by infusing carbon nanotubes and electrolytes into a paper substrate. The material can be folded, rolled up, or molded to any convenient shape with no effect on power capacity. Operating temperature range is -100 to 300 degrees F. One of the co-authors is quoted: 'We're not putting pieces together — it's a single, integrated device. The components are molecularly attached to each other: the carbon nanotube print is embedded in the paper, and the electrolyte is soaked into the paper. The end result is a device that looks, feels, and weighs the same as paper.'" The researchers haven't yet developed a high-volume way to manufacture the devices. They envision ultimately printing sheets between rollers like newsprint.

    Instead of a paper-cut you get a electric paper-shock?

      Science labs around the world will soon migrate from the 'leave a charged capacitor lying around' trick to the 'can you take that note over there to Mr Smith' trick.

      Think of the things terrorists can do with a paper airplane... Fixed that for you.

    what do we - as a species - want to do?
    If the new technology is used in the future the same way it was used in the past, the first priority is probably to make better porn.
