Power generation and storage for microelectromechanical systems, miniaturized biomedical devices, sensors and integrated on-chip components, can significantly benefit from the fabrication and integration of planar thin film supercapacitors. Supersonic cluster beam deposition (SCBD) of nanostructured carbon (ns-C) is a versatile technique for the fabrication of porous carbon thin films. SCBD consists in a random stacking of low kinetic energy nanoparticles producing films with very low-density and high porosity. The use of supersonic expansions for carbon cluster deposition allows to obtain very high deposition rates and highly collimated beam (divergence
