Nano-engineered paper' battery created

Just when you thought we have seen everything hold onto those laptop computers, folks. Now, they have come out with a battery that is made of paper.

Cellulose, an organic plant compound, makes up most of the paper, cotton, and linen products that we use every day.

Will cellulose become the next generation component for our batteries, too?

A working prototype "paper battery" has been created by the researchers at Rensselaer Polytechnic Institute in New York. This battery is made out of 90 percent cellulose, which is also used in our loose-leaf paper, newsprint, and grocery bags.

This paper battery, however, has a coating of lithium and contains carbon nanotubes.

The photo I saw of this working prototype looks like a thin sheet of black paper that measures roughly an inch square.

What is cool about this piece of paper is that it holds an electrical charge.

The paper battery is actually bendable (which I saw in the photo), and the application uses for a battery like this are endless.

This battery operates using the same electrical principles as any normal battery used today.

In my research, I discovered that the paper battery can be as large as a regular newspaper page, or it can be cut down to the size of a postage stamp.

This new battery can be rolled, twisted, folded, or cut into any number of shapes without damage or loss of efficiency. Paper batteries can also be "stacked" or connected together like a ream of printer paper to increase the total power output.

"It's essentially a regular piece of paper, but it's made in a very intelligent way," said Professor Robert Linhardt, at Rensselaer.

"We're not putting pieces together it's a single, integrated device," he said. "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 operating temperatures of this battery are extreme it is rated at -100 degrees below zero to 300 degrees Fahrenheit, so it is very possible this might be the battery NASA would use on future space satellites or to provide power in electronic systems that will be on the next mission to the moon.

Another use of this paper is it can be inserted under the human skin to power medical devices such as pacemakers.

Some printed paper batteries were made without adding any electrolytes.
