    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%.

    Abstract: The battery (10) comprises a casing (12) housing prismatic cells (14) stacked in a longitudinal direction (X), and comprising spacers (16) between the cells (14). Each spacer (16) comprises at least one spacer element (18; 22) comprising a curved wall, the spacer element (18; 22) being deformable when compressed in the longitudinal direction (X) while extending in a transverse direction (Y) perpendicular to the longitudinal direction (X). The extension of each spacer element (18; 22) in the transverse direction (Y) is free on a first length, then limited by a contact. The battery (10) comprises cooling fluid, the curved wall having two faces, each face being in contact with cooling fluid.

    Abstract: The invention relates to a housing for an electric battery, the housing includes two components, namely a support for a prismatic cell assembly, and a cover for covering the prismatic cell assembly. The locking system includes a lever attached to a first of the two components and rotationally guided relative to the first of the two components between a locked position and an unlocked position, and which, in the locked position, is elastically deformed so as to wedge itself into hooking means integral with the first of the two components, and come to bear against a surface of the second of the two components, ensuring that the two components are joined together.

    Abstract: The invention relates to a method for depositing an electrical insulation layer on an electrochemical cell including a lower wall, a side wall and an upper wall on which a positive terminal and a negative terminal are arranged, the side wall and the upper wall being connected by a peripheral edge. The deposition method includes a step of depositing an electrical insulation layer during which the electrical insulation layer is deposited on the lower wall, the side wall, and only on one border of the upper wall the border extending from the peripheral edge toward the interior of the upper wall over a distance d, so as to form an electrical insulation strip covering the border and surrounding a central zone of the upper wall.
