In a recent publication*, a multidisciplinary team from IMCN (groups of Alexandru Vlad and Luc Piraux) have demonstrated a large footprint areal capacitance/energy enhancement in microsupercapacitors based on 3D nanoarchitectured electrodes. This result was obtained in microscale energy storage devices based on template-assisted electrodeposition of three-dimensionally interconnected metallic nanowire network, and its subsequent laser-patterning to form interdigitated nanostructured electrodes. The patterned nanowire networks were functionalized with the polyaniline active electrode material via an electroless deposition procedure.
