Rice University researchers test flexible, three-dimensional
supercapacitors
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 electronics.
The Rice lab of chemist James Tour discovered last year that
firing a laser at an inexpensive polymer burned off other elements and left a
film of porous graphene, the much-studied atom-thick lattice of carbon. The
researchers viewed the porous, conductive material as a perfect electrode for
supercapacitors or electronic circuits.
