<p>Preparation of a nanometric carbonaceous particles dispersed solution containing neither binder nor dispersant, comprises preparing a polymeric matrix of determined viscosity, introducing a fraction of the carbonaceous particles and a fraction of a wetting agent i.e. solvent of the matrix, maintaining the mixture under agitation until obtaining a stable ground of viscosity and repeating the introduction of carbonaceous particles and the agitation until exhaustion of the carbonaceous particles and solvent. Independent claims are included for: (1) a nanometric carbonaceous particles dispersed solution comprising carbonaceous particles (1-4% mass/volume, 2-4% mass/volume) in suspension, a polymeric matrix (20-40 vol.%) and a wetting agent, solvent of the polymeric matrix, where the dispersed solution contains neither binder nor dispersant; (2) preparation of a conducting carbonaceous layer on a substrate comprising preparing a dispersed solution of carbonaceous nanometric particles, depositing a layer of the dispersed solution on the substrate, drying the layer with free air, eliminating the polymer by heat treatment and the carbonaceous particles that are non-adherent with the substrate, by brushing; and (3) an electrical energy storage system comprising a metallic current collector and an active film, where the current collector is covered with a conductor layer obtained using the solution of carbonaceous particles.</p> |
