Printable Batteries Should Arrive Next Year

Posted by timothy on from the return-to-the-goodness-of-aa dept.

FullBandwidth writes "Paper-thin batteries that can be printed onto greeting cards or other flexible substrates have been demonstrated at Fraunhofer Research Institution for Electronic Nano Systems in Germany. The batteries have a relatively short life span, as the anode and cathode materials dissipate over time. However, they contain no hazardous materials."

    Even if this were plausible, you'd be ignoring the energy it takes to run the photocopier.

    Not a problem. We'll just use more photocopiers so we can print more batteries. You're not thinking outside the box.
