摘要： The invention relates to a method for preparing a coating material for coating an electrode carrier. For known coating materials, the problem exists that these either cannot be stored without the input of energy or cannot be produced without quality fluctuations. To solve these problems, the method according to the invention comprises the steps of a) providing a dry mixture containing at least i) an active material, ii) a conductivity additive, as well as iii) a fluorine-containing polymer binder, b) bringing the dry mixture into contact with a solvent mixture containing ethylene carbonate and/or propylene carbonate, c) thoroughly mixing the solvent mixture and the dry mixture at a temperature of more than 80° C. until the fluorine-containing polymer binder has dissolved completely in the solvent mixture, wherein d), after the fluorine-containing polymer binder has dissolved completely, the mixture obtained is cooled to a temperature of less than 40° C. and the mixture obtained cures during the cooling process and e), the mixture obtained is granulated during or after the curing process. The granules obtained with the method can be stored without problems and can be used without quality fluctuations to coat an electrode carrier.
