Graphene nonwovens for supercapacitors?

Crumpling a piece of graphene ‘paper’ – formed by bonding together layers of the two-dimensional form of carbon – can yield new properties that could be useful for creating extremely stretchable supercapacitors to store energy for flexible electronic devices. 

This discovery is reported by MIT’s Xuanhe Zhao, an assistant professor of mechanical engineering and civil and environmental engineering and his team, who believe the new, flexible supercapacitors should be easy and inexpensive to fabricate. 

“Graphene paper is a good candidate for making supercapacitors, because of its large surface area per mass and the development of flexible electronic devices, such as wearable or implantable biomedical sensors or monitoring devices, will require flexible power-storage systems,” says Zhao.
