New kind of supercapacitor made without carbon

Energy storage devices called supercapacitors have become a hot area of research, in part because they can be charged rapidly and deliver intense bursts of power. However, all supercapacitors currently use components made ...

Tiny wires could provide a big energy boost

Wearable electronic devices for health and fitness monitoring are a rapidly growing area of consumer electronics; one of their biggest limitations is the capacity of their tiny batteries to deliver enough power to transmit ...

Scientists create quick-charging hybrid supercapacitors

The dramatic rise of smartphones, tablets, laptops and other personal and portable electronics has brought battery technology to the forefront of electronics research. Even as devices have improved by leaps and bounds, the ...

Laser-induced graphene 'super' for electronics

Rice University scientists advanced their recent development of laser-induced graphene (LIG) by producing and testing stacked, three-dimensional supercapacitors, energy-storage devices that are important for portable, flexible ...

Crumpled graphene could provide an unconventional energy storage

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 ...

Flexible battery, no lithium required

(Phys.org) —A Rice University laboratory has flexible, portable and wearable electronics in its sights with the creation of a thin film for energy storage.
