Abstract (en)
[origin: WO2016124756A1] The present invention concerns the field of components for storing energy and relates to a method of depositing nano-/microparticles, including at least graphene sheets, on a support (8), comprising the following steps: oxidizing at least the graphene sheets; suspending the nano-/microparticles in at least one solution comprising at least water as solvent; spraying each suspension onto a substrate (15) by hydrodynamic instability; heating the substrate (15) during each spraying, in order to promote the complete evaporation of the solvent from each part of each suspension sprayed onto the substrate (15), to a temperature below or equal to one and a half times the boiling temperature of each of the aforementioned solutions and lower than or equal to 200 degrees Celsius; and reheating the deposit (1) after the spraying or sprayings to a temperature that is sufficient to deoxidize at least the oxidized graphene present in the deposit (1) and higher than the temperature of the substrate (15) during the deposition step.
