Researchers have created a new technology that could have an important use in green cars

Stanford University researchers have created a new solution that is able to transform regular office paper into a flexible, conductive battery using a layer of carbon nanotubes.

Made of millions of interconnected carbon nanotubes, researchers discovered paper is able to support carbon nanotubes better than other normal household items.

“Taking advantage of the mature paper technology, low cost, light and high-performance energy-storage are realized by using conductive paper as current collectors and electrodes,” Stanford researchers noted in the Proceedings of the National Academy of Sciences report.

Performance of the nanomaterial withstood acidic solutions, or when it was crumbled, folded, or otherwise manipulated.

“Society really needs a low-cost, high-performance energy storage device, such as batteries and simple super capacitors,” said Yi Cui, Stanford assistant professor of materials science and engineering, during an interview with Reuters.

After a sheet of paper is coated with the carbon nanotube ink, it is dipped into a "lithium-containing" solution that also has electrolytes -- the electrolytes are necessary to generate current.

The paper battery also could be used in hybrid or electric vehicles, researchers note, while also making batteries last longer.  If Stanford researchers are successful with its research, it's possible paper electronics could also be developed, but that is a long-term goal of the project.

The idea of "paintable" energy storage isn't new, but very few researchers have been able to develop realistic technologies.

The battery is not the paper

Sounds to me like the paper is just the vehicle for the battery, which is really the nanotube structure. In that case they just need to find a material that is densely woven enough to hold the nanotubes correctly but still flexible. Would silk or some other kind of cloth do the job? I'd pay extra for a shirt or other clothing with charge/discharge leads.

Sounds like an interesting idea. I can see soldiers in the not too distant future turning in all their clothes and body armor for these battery embedded equivalent that you speak of. With the amount of electronics one must carry into the modern battlefield, this could save a lot of weight, kill two birds with one stone kinda deal. Better yet, enable the clothes to charge wirelessly and you got a winner.

Oh yeah... lets use all the paper on cars ... but what happend if we ran out of recycled paper????

so ... we make cars with no emissions and cut all the trees to create batteries????

that doesn't sound like helping the environment

There is always Hemp ;)

OH SWEET JESUS NOT HEMP!

I yearn for the day when common sense trumps cross-eyed fear mongering, if only on the subject of Hemp and Marijuana.

Seriously?

We're not taking about oil here. We grow more fucking trees.

I'm not saying deforestation isn't a problem, but it's a very fixable problem. We aren't going to run out of trees.

Calm down.

If you could incorporate flexible, thin-film solar cells into the clothing they could be self-recharging.

paper weight

No matter how it is packaged, a battery works by storing electrons. Since electrons are a tiny fraction of the mass of any molecule, batteries will always have low specific energy, but I guess the research supports a lot of otherwise unemployable researchers.

Sooo wrong it's funny.

LMAO! How about we put the electrons in a blender first and then pour them slowly into the battery.

Careful, don't spill any!

If research is so useless why does my phone weigh 82 grams, when my first phone had a shoulder strap?

It's got what plants crave!
Haha, couldn't resist!

You should have.
