Zusammenfassung: | To provide electrode materials and processes for their preparation.SOLUTION: The present application describes an electrode material comprising particles of an electrochemically active material dispersed in a polymer binder, the polymer binder being an acidic polymer or a mixture comprising a binder soluble in an aqueous solvent or a non-aqueous solvent (for instance, NMP) and an acidic polymer. The present application also further relates to processes for the preparation of the electrode material and electrodes containing the material, as well as to the electrochemical cells and their use. The present technical field generally relates to electrode materials and processes for their preparation, (for instance, electrode materials using a binder containing an acidic polymer or a water-soluble binder and an acidic polymer). The present application also relates to the use of the electrode materials for the preparation of electrodes and their use in electrochemical cells (for instance, lithium-ion batteries).SELECTED DRAWING: None
