Abstract:
A method for preparing a paste-like composition including carbon-based conductive fillers, at least one polymeric binder, at least one solvent, and at least one polymeric dispersant being different from the binder. Also, the paste that can result from said method, and to the uses thereof, in pure or diluted form, in particular for the manufacture of Li-ion batteries and super-capacitors.

Claim (Index 1):
A process for the preparation of a pasty composition based on carbon-based conductive fillers, comprising:\n (i) the introduction into a kneader, and then the kneading, of carbon-based conductive fillers, of at least one polymeric binder, of at least one solvent and of at least one polymeric dispersant distinct from said binder, selected from the group consisting of poly(vinylpyrrolidone), poly(phenylacetylene), poly(meta-phenylene vinylidene), polypyrrole, poly(para-phenylene benzobisoxazole), poly(vinyl alcohol) and their mixtures, in order to form a masterbatch comprising a proportion by weight of 15% to 40% of carbon-based conductive fillers and of 20% to 85% of solvent and in which the ratio by weight of the polymeric binder to the carbon-based conductive fillers is between 0.04 and 0.4 and the ratio by weight of the polymeric dispersant to the carbon-based conductive fillers is between 0.1 and 1, limits included; (ii) the extrusion of said masterbatch in a solid form; and (iii) the diluting of said masterbatch in a solvent which is identical to or different from that of stage (i), in order to obtain a pasty composition, the pasty composition having a viscosity of between 200 and 1000 mPa\u00b7s at a temperature of 23\u00b0 C.
