Porous Carbon-based materials for electrochemical energy storage

Nanostructured carbons with high surface-to-volume ratio hold chemical inertness, good electrical conductivity and low density that are beneficial in a number of emerging energy storage technologies. The coupling of a gas-phase technique for the preparation of aerosols of carbon nanoparticles with free jet supersonic expansions for the formation of molecular beams enables the deposition of carbons materials with high porosity and controlled nanostructure. Here, this approach is used for (i) the fabrication of carbon thin films and nanocomposites (e.g. C-Ni and C-Ti) with enhanced interfacial properties, (ii) for the study of the electrochemical processes at the interface between porous carbon and electrolytic media (e.g. ionic liquids) and (iii) for the integration of carbon-based electrodes into miniaturized energy storage devices (e.g. microsupercapacitors).
