Abstract: The manufacturing method is intended to manufacture an electrode (28) comprising a substrate (26) and at least one film (22, 24) coating the substrate (26). The method comprises calendering a dry powder mixture (12) in a first calendering device (14) including at least two cylinders comprising a first cylinder (18a) having a first rotation speed V1 and a second cylinder (18b) having a second rotation speed V2, the dry powder mixture (12) being supplied between the first (18a) and second (18b) cylinders. The percentage difference v1−v2/v1 between the first rotation speed V1 and the second rotation speed V2 is comprised between 1% and 40%.
