The technology behind paper batteries

Hi, does anyone here knows the technology behind paper batteries:
Any documents?

<Please Dont give me LINKS>
thank you

Paper Battery????

Battery Handbook may be tried..

Re: Paper Battery????

Try this one:
"Urine-activated paper batteries for biosystems"
Abstract
The first urine-activated laminated paper batteries have been demonstrated
and reported in this paper. A simple and cheap fabrication process for the
paper batteries has been developed which is compatible with the existing
plastic laminating technologies or plastic molding technologies. In this
battery, a magnesium (Mg) layer and copper chloride (CuCl) in the filter
paper are used as the anode and the cathode, respectively. A stack consisting
of a Mg layer, CuCl-doped filter paper and a copper (Cu) layer sandwiched
between two plastic layers is laminated into the paper batteries by passing
through the heating roller at 120 ◦C. The paper battery is tested and it can
deliver a power greater than 1.5 mW. In addition, these urine-activated
laminated paper batteries could be integrated with bioMEMS devices such
as home-based health test kits providing a power source for the electronic
circuit.
