 |

Researchers at Rensselaer Polytechnic Institute have made a small paper battery, about the size of a postage stamp. It puts out about 2.3 Volts. The objective is to make reems of these lightweight, cheap power sources for the next generation of electronic gadgets.

The battery contains carbon nanotubes, each about one millionth of a centimetre thick, which act as an electrode. The nanotubes are embedded in a sheet of paper soaked in ionic liquid electrolytes, which conduct the electricity.
The flexible battery can function even if it is rolled up, folded or cut.
Although the power output is currently modest, Professor Linhardt said that increasing the output should be easy.
"If we stack 500 sheets together in a ream, that's 500 times the voltage. If we rip the paper in half we cut power by 50%. So we can control the power and voltage issue."
Because the battery consists mainly of paper and carbon, it could be used to power pacemakers within the body where conventional batteries pose a toxic threat. |

| That's pretty cool, I wonder what they'll think of next. |
