Paper-Thin Batteries Provide Bendable Power
SkinnyGuy writes "New carbon nanotube-based technology could literally allow companies to paint layers of electricity-holding lithium-ion on standard pieces of paper. The possibilities are endless." You can also read the actual paper.
For the electrical geeks, the energy density is 108 mWh/g. Anyone want to compare that to a standard AA rechargeable?

I wonder if the spying technology that doesn't reach the public, if there is such thing, has already reached a size that makes it impossible to find by non-electronic means. I wonder if such deviced didn't exist until the paper-thin batteries were invented.
I read the paper and it was Shockingly Powerful.
"... embed it in a carbon nanotube matrix, and it really is that simple ..."
I swear, what are carbon nanotubes NOT good for?

I want a battery that I can recharge by holding either end and shuffling my socks on the carpet.
That Instantly went to "how will this advance the sex-toy market" instantly before thinking of good practical or scientific uses?

Perhaps I'm wrong, but I seem to remember a Slashdot thread last year on this. What I am clear on is that this is the same scientist and the same material shown over at Gizmag Dec/2009.

This appears to be more of a refinement of the discovery and methods first reported by Dr. Yi Cui and team. Now the question is. When will we finally see products? Another year?
I'm convinced that we're pretty much forever stuck with the battery technology we have today. Of all the hype I've heard over the years of some great new battery technology, nothing of any major consequence has ever panned out. I didn't even read the article, cause I'll only believe it when I see it.
If I didn't have absolutely NOTHING to do, I wouldn't be here.
What about toxic effects on children? Right now we are dealing with lead paint and asbestos in our homes. What kind of problems will we see with kids eating this kind of paint/paper? If you don't think they would eat this, just look at how many of them still get pennys stuck up their noses. Eating paper is no big deal for them.

And in jurisdictions where waste segregation and recycling is taken seriously we'll now have to dispose of this paper as chemical waste.

Sweet! Now I have the much needed power supply for the lasers. Time to break out the duct tape.
My imagination machine must be broken today, but I'm having a hard time seeing what this would be good for? Is it more useful to have the battery spread all over the place than it is to have it nicely tucked away in a protected compartment, easy to access, detach and replace (unless you're an iPiddle user)?
The only thing I could really see this being useful for is in cases where concentrated battery weight throws off balance or maneuverability for moving equipment, like electric cars or bicycles, and even then, this isn't saying you'd need less weight in batteries, you could just distribute the battery weight load more evenly.
Orr...actual digital 'paper', that records pen (stylus) strokes on a piezoelectric surface to an embedded memory card for later uploading. This could be made to look much more like a standard piece of paper than today's attempts, just a bit thicker, like writing on parchment or leather. Of course, you'd have to depend on additional advances in display thinning technology for user feedback. And there would still be an unbalanced weight load on the device due to the memory storage requirement. And it's not like you can fold it in half and stick it in your pocket (bendable, not necessarily foldable).
Any other actual usage ideas where this would provide a practical advantage over current technology?

I came up with a "your mom" joke, but I think I better keep it to myself...
Perhaps I'm trolling, perhaps I'm not.
The delivery dates on these types of products is about as endless as the possibilities. And for once it is just not the net that ballyhoos these new inventions. Popular Science has reported on endless breakthroughs through many decades as have other magazines. Yet the number of these ideas that actually make it into production in any reasonable amount of time is next to none at all. Printing batteries on flexible paper sounds great. But give us thirty years and batteries might be a thing of the past. If it isn't some fancy kind of capacitor it will be some other newly thought of technology that hits the streets.
I predicted the same thing with Linux. I'm a Linux fan and daily user. But I remarked on many occasions that the battle between Linux and Windows was irrelevant as somewhere a new OS would crop up that might sweep the field. It might be Chrome. It may be something yet to be discussed. But changes are occurring and not only are they occurring faster but the steps of increase are getting greater as well. Batteries have shown distinct limits as have Windows products. Expect sweeping changes.
Combine this with a printed solar cell... that could be interesting:

That seems kind of dangerous.
how about on the side of your car, and then also add some solar paint ....the combo of the 2 turns your car into a self generating self contained energy construct, and the fact you do not need a bulky battery you coudl also just do without a bulky heavy one sitting
in there, you could end up getting more miles for the gallon (or what is it for electric cars, kilojoules???)
