Paper batteries you can bend and cut.

Made from 90 percent cellulose plus carbon nanotubes acting as electrodes, this paper like composite acts either as a battery or as a supercapacitor. No water is needed so this material can function from 100 below zero up to 300 degrees Fahrenheit.

Along with use in small hand held electronics, the paper batteries’ light weight could make them ideal for use in automobiles, aircraft, and even boats. The paper also could be molded into different shapes, such as a car door, which would enable important new engineering innovations.
“Plus, because of the high paper content and lack of toxic chemicals, it’s environmentally safe,” Shaijumon said.

Print batteries by the roll.

The team has not yet developed a way to inexpensively mass produce the devices. The end goal is to print the paper using a roll-to-roll system similar to how newspapers are printed.

Details of the project are outlined in the paper “Flexible Energy Storage Devices Based on Nanocomposite Paper” published Aug. 13 in the Proceedings of the National Academy of Sciences.

How long can the paper batteries last? Or does the bigger the battery the longer it lasts?

would the batteries be able to go into electronics we have now?? Or would we have to wait to they come out with electronics who run on paper batteries??

Unfortunately with R & D the research proves a concept but the development often takes years.

Is it really development problems or could it have something to do with the fact that the current battery companies are somehow influencing the developers not to come out with it too fast because it would obviously hurt their profits on the current batteries they now market

I had no idea there was a paper battery! is that even possible?!

SO WHAT"S A SUPERCAPACITOR?
