A battery that resembles a small sheet of paper could pave the
way for a new generation of extremely flexible, cheap, and
environmentally friendly energy sources.
A traditional battery has three key elements: an electrolyte
solution made up of positive and negative ions, two electrodes
made of different materials between which the ions flow, and a
separator membrane through which positive and negative ions
pass in opposite directions. Attempts to make batteries less
bulky and more flexible have met with limited success, largely
