Claim:
1. Process for manufacturing an anode usable in a cell of a lithium-ion battery comprising an electrolyte based on a lithium salt and a non-aqueous electrolyte solvent, the anode being based on a polymer composition obtained by melt processing and without solvent evaporation, that is the product of a hot compounding reaction between an active material and additives comprising a polymer binder and an electrically conductive filler, wherein said binder is based on at least one crosslinked elastomer and wherein said additives furthermore comprise at least one non-volatile organic compound which has a boiling point above 150° C. at an atmospheric pressure of 1.013×10 5 Pa, is in a solid state at room temperature and which is usable in said non-aqueous electrolyte solvent, the composition comprising said active material in a mass fraction greater than or equal to 85%, wherein said process comprises: a) melt compounding, without said solvent evaporation, in an internal mixer or an extruder, of said active material and said additives and said at least one organic compound in said solid state in order to obtain said composition in a crosslinkable state; and b) crosslinking and optionally hot forming said composition, in order to obtain a crosslinked composition.
