Paper batteries could soon be powering household gadgets, medical devices and electric vehicles. Scientists have devised a new kind of ultra-thin battery that resembles a simple sheet of black paper.
More than 90 per cent of the battery is made of cellulose, the same plant material used in newsprint, writing paper and packaging.
Researchers embedded the paper with carbon "nanotubes", tiny tube-like structures which act as electrodes.
The body of the paper is infused with an electrolyte, a substance containing free electrically charged atoms, or ions.
The paper battery can operate at temperatures as high as 149ºC and as low as -73ºC.

Or in plain English, with nanotechnology they have succeeded in enlarging the capacity of a paper capacitor. Interesting, now they would just have to succeed in accelerating the charging process. That would finally be the ultimate battery.

Well at least we just might have no batteries in the landfills.
