CATHODE COATED WITH A FILM COMPRISING LiFePO4 AND A WATER-SOLUBLE BINDER, PRODUCTION METHOD THEREOF AND ELECTROCHEMICAL SYSTEM

摘要

The invention relates to a method of preparing an electrochemical electrode which is partially or totally covered with a film that is obtained by spreading an aqueous solution comprising a water-soluble binder over the electrode and subsequently drying same. The production cost of the electrodes thus obtained is reduced and the surface porosity thereof is associated with desirable resistance values.
