Crumpled graphene could provide an unconventional energy storage

Two-dimensional carbon “paper” can form stretchable supercapacitors to power flexible electronic devices.

When someone crumples a sheet of paper, that usually means it’s about to be thrown away. But researchers have now found that crumpling a piece of graphene “paper” — a material formed by bonding together layers of the two-dimensional form of carbon — can actually yield new properties that could be useful for creating extremely stretchable supercapacitors to store energy for flexible electronic devices.
