For applications that need only small amounts of power, flexible paper batteries look promising by offering a viable alternative to current batteries. These batteries use a paper layer containing the electrolyte as the separator between the anode and the cathode. They are easy and cheap to manufacture because they are produced using printing machines and environmentally friendly because of easy disposal. And as they're thin and flexible, they can be tailored for a large variety of applications, including cosmetics, smart cards, sensors, greeting cards or semi-active RFIDs.
