Printed power for printed electronics

New Scientist is reporting on printable batteries with carbon nanotube (CNT) electrodes.

The batteries were created by George Gruner and colleagues at the University of California in Los Angeles, US, and use the same zinc-carbon chemistry as ordinary non-rechargeable batteries.

To make the battery, a layer of nanotubes is first deposited in the form of “nanotube ink” [...]

Paper battery/supercapacitor

Researchers at Rensselaer Polytechnic Institute have developed thin, flexible energy storage devices consisting of more than 90 percent cellulose. The paper is infused with aligned carbon nanotubes (electrodes), and an electrolyte (e.g. an ionic liquid). The technology allows to fabricate batteries, supercapacitors, or devices which combine both functions.

According to the press release, the devices can [...]
