Abstract
The invention relates to a method for producing a material for a composite electrode. The method is intended for the preparation of a composite material consisting of an active electrode material M1, a material C1 conferring electronic conductivity, an organic binder and a salt, said binder comprising a polymer P1 having an O, N, P or S heteroatom mass content of 15% or higher, a polymer P2 having an O, N, P or S heteroatom mass content of 5% or less, and a nonvolatile liquid organic solvent S1. It includes a step consisting in preparing a viscous solution containing at least one polymer P1, at least one polymer P2, a material C1, an active electrode material M1 and at least one nonvolatile solvent S1, and a step consisting in forming a film from the viscous solution obtained.
