Microscale supercapacitors provide an important complement
to batteries in a variety of applications, including portable elec-
tronics. Although they can be manufactured using a number of
printing and lithography techniques1­3
, continued improve-
ments in cost, scalability and form factor are required to
realize their full potential. Here, we demonstrate the scalable
fabrication of a new type of all-carbon, monolithic supercapaci-
