Stanford scientists create paper batteries that work when crumpled

Highly conductive paper for energy-storage devices
Stanford scientists have developed featherweight, pliable batteries and supercapacitors in the form of everyday paper.
By coating a sheet of paper with ink made of carbon nanotubes and silver nanowires, the scientists were able to construct a highly conductive storage device that’s both low-cost and high-performance.
(The difference between a battery and a capacitor, you ask? both hold energy to be converted to electricity, but capacitors hold it for a shorter period of time. On the other hand, they can store and discharge energy much more rapidly.)
The batteries are so strong that you can crumple them and the performance does not degrade.Led by assistant professor of materials science and engineering Yi Cui, who previously created nano-size batteries using plastics, the researchers developed a solution that is more durable than conventional batteries.
