METHOD FOR PREPARING AN ELECTRODE COMPOSITION

摘要

The invention relates to a method for preparing an electrode composition, including a step of forming a suspension, in an unbuffered aqueous acid medium having a pH of 1 or in a buffered acid medium having a pH less than or equal to 4, containing an electrode active material in the form of particles of an element M selected from Si, Sn, and Ge, a polymer binder having reactive groups capable of reacting with hydroxyl groups in an acid medium, and an agent generating electronic conductivity. The invention also relates to the electrode obtained according to the method, as well as to a battery including such an electrode.
