Abstract: An electrically conductive adhesive composition, free of metals and metal salts comprising: - an adhesive component selected from the group consisting of polyethylene-vinyl acetate, elastomer polyolefins, polyvinyl butyral, polyacrylic acid, polyacrylates and poly(methyl methacrylate) in quantities of 5% to 40% by weight and - an electrically conductive component comprising acetylene or carbon black nanoparticles, carbon nanotubes and flakes or plates of graphene or graphene derivatives in quantities of 60 to 95% by weight, the percentages by weight being referred to 100 parts by weight of the adhesive component and electrically conductive component, wherein said electrically conductive component consists of: - acetylene or carbon black nanoparticies from 15 to 45% by weight, - carbon nanotubes from 5 to 25% by weight, and - flakes or plates of graphene or graphene derivatives from 35 to 70% by weight, the percentages by weight being referred to 100 parts by weight of said electrically conductive component, - a solvent compatible with the polymer component in quantities of 50% to 90% by weight referred to 100 parts of the composition consisting of polymer component, electrically conductive component and solvent. The adhesive composition is advantageously used in photovoltaic applications that require welding of components at low temperature and in power-supply or electronic applications that require the mechanical and electrical serial connection of electrodes in batteries, supercapacitors and multi-component electronic systems.
