The present invention pertains to an electrode-fornning composition [composition (C)] comprising: (a) an aqueous latex comprising at least one fluoropolymer [polymer (F)] comprising recurring units derived from vinylidene fluoride (VDF), at least one hydrogenated monomer [monomer (H)] and, optionally, at least one other fluorinated monomer [monomer (F)] different from VDF, and, homogeneously dispersed therein, (b) at least one powdery electrode-forming material consisting of Sulphur [material (E)], (c) at least one powdery electrically conducting material [material (C)], (d) optionally, at least one surfactant [surfactant (S)], (e) optionally, at least one binding agent [agent (B)], and (f) optionally, less than 10% by weight, based on the total weight of the composition (C), of at least one organic solvent [solvent (S)], wherein the polymer (F) in the aqueous latex is under the form of primary particles having an average primary particle size of less than 1 μm, as measured according to ISO 13321. The present invention also pertains to a process for the manufacture of said composition (C) and to use of said composition (C) in a process for the manufacture of a positive electrode for a Lithium-Sulphur battery. |
