i m not asking about normal batteries i m taking about the one being used in nokia 888 it is a slim paper like phone which can be even folded like paper..

Googling it, I don't think that actually means anything... they offer no description and I've never heard of anything close unless they are going to do a really small lead-acid battery. There are, however, flexible polymer batteries... http://www.sciencedaily.com/releases/2007/03/070323141052.htm

They are probably referring to a battery in which the electrodes are replaced by a liquid redox couple. One example of this is the soluble iron/soluble chromium type liquid flow batteries. The two solutions are separated by a membrane that keeps separate the two solutions (a redox couple). A recent development uses vanadium II/vanadium III as the redox couple.
