摘要： The invention relates to a method for producing material for composite electrode. The aim of said invention is to produce a composite material consisting of an active electrode material M1, a conductive material (C1), an organic binder and a salt. Said binder comprises a polymer (P1) whose mass composition in heteroatoms O, N, P or S is equal to or higher than 15 %, a polymer (P2) whose mass composition in heteroatoms O, N, P or S is equal or lower than 5 %, and an liquid non-volatile organic solvent (S1). Said method comprises a stage for preparing a viscous solution containing at least one type of polymers (P1) and P2, the material C1, the active electrode material M1 and at least one type of the liquid non-volatile organic solvent S1, and a stage consisting in forming a film from the thus obtained viscous solution.
