These days, society really needs a low-cost, high-performance energy storage device, such as batteries and simple super-capacitors. For this, recently a new technology has come up with a battery made of paper to charge devices. The approach relies on the use of carbon nanotubes - tiny cylinders of carbon - to collect electric charge. Here a piece of paper is dipped into ink infused with carbon nanotubes and silver nanowires, it morphs into a real battery. Then, the piece of paper is crumpled and it still works.
Stanford scientists are harnessing nanotechnology to quickly produce ultra-lightweight, bendable batteries and supercapacitors in the form of everyday paper. The paper batteries are treated with a nanotube ink, baked and folded into electrical generating sources.
Simply coating a sheet of paper with ink made of carbon nanotubes and silver nanowires makes a highly conductive storage device. Like batteries, capacitors hold an electric charge, but for a shorter period of time. However, capacitors can store and discharge electricity much more rapidly than a battery.
