The invention relates to an electrical energy storage assembly comprising an envelope and a capacitive element (30) contained in the envelope, said envelope comprising: at least one side wall (22); and two bottom walls (41) each located at an end of the side wall. Said storage assembly comprises at least one electroconductive intermediate connection part (50) to be arranged between the capacitive element and a bottom wall (41), in addition to a covering plate (51) for covering the end of the capacitive element (20), said covering plate (51) including at least one vent (53) for the passage of a fluid. The covering plate (51) is fixed to the capacitive element in such a way as to be in electrical contact therewith, and the intermediate connection part (50) is also fixed to the envelope in certain areas enabling a deformation of the bottom wall in relation to the intermediate connection part.

1. An electrical energy storage assembly comprising an envelope and a capacitive element contained in the envelope, the envelope comprising a tubular element forming a side wall and two bottom walls each positioned at one end of the side wall, the envelope also comprising at least one cover placed at one end of the tubular element, said cover comprising a covering wall intended to cover the end of the tubular element and forming one of the two bottom walls of the envelope,wherein the storage assembly further comprises at least one electrically conductive intermediate connection part, said intermediate connection part having a covering plate provided with at least one through opening forming a vent for the passing of a fluid, the periphery of said covering plate comprising a peripheral skirt perpendicular to said covering plate, wherein said intermediate connection part is arranged between the capacitive element and the cover such that its covering plate extends parallel to a plane along which the covering wall of the cover extends and its peripheral skirt covers a part of the side wall of the envelope, said covering plate being intended to cover and being secured to the end of the capacitive element, so that it is in electrical contact with the capacitive element, wherein the covering plate is devoid of securing regions with the cover of the envelope, and wherein the peripheral skirt of the intermediate connection part is secured by securing regions to the side wall of the envelope and to the cover so as to be in electrical contact with them, said securing regions being regions in which the deformation of the bottom wall relative to the intermediate connection part is minimum. 2. The energy storage assembly according to claim 1, wherein the intermediate connection part is secured to the envelope and/or to the cover by gluing or welding. 3. The storage assembly according to claim 1, wherein the tubular element comprises a base closing the side wall at one of its ends and forming one of the two bottom walls, the cover being placed at the other of its ends. 4. The storage assembly according to claim 1 wherein the intermediate connection part is arranged inside the side wall of the envelope, the covering plate extending parallel to a plane along which the base of the envelope extends, the securing regions of the intermediate connection part preferably comprising a surface located on the peripheral skirt of said intermediate connection part and connected to an inner surface of the side wall. 5. The storage assembly according to claim 1, wherein the cover comprises a peripheral skirt intended partly to surround the outer surface of the side wall of the tubular element. 6. The storage assembly according to claim 5, wherein the intermediate connection part is arranged so that its peripheral skirt is positioned between said side wall of the envelope and the peripheral skirt of the cover, the securing regions of the intermediate connection part comprising a surface located on said peripheral skirt of the intermediate connection part and connected to an inner surface of the skirt of the cover and to an outer surface of the side wall of the envelope. 7. The storage assembly according to claim 1 or 2, wherein the covering wall of the cover is sized to have smaller dimensions than the end of the side wall of the envelope so that it can be pressed into the envelope, the intermediate connection part being arranged so that its covering plate extends parallel to the covering wall of the cover, and so that its peripheral skirt is positioned between an edge of the cover extending perpendicular to the covering wall of the cover and the inner surface of the side wall of the envelope, the securing regions of the intermediate connection part comprising a surface located on the peripheral skirt of the intermediate connection part. 8. The storage assembly according to claim 1, comprising two intermediate connection parts each positioned at one end of the capacitive element. 9. The energy storage assembly according to claim 1, wherein the intermediate connection part comprises at least one projection extending outwardly perpendicular to the covering plate and in the same direction as its peripheral skirt, this projection being intended to be embedded in the capacitive element. 10. A module comprising a casing in which there are arranged at least two electrical energy storage assemblies according to claim 1. 11. A method for assembling an electrical energy storage assembly comprising an envelope having a so-called side wall and two bottom walls each positioned at one end of the side wall, and a capacitive element intended to be contained in the envelope, wherein the method comprises at least the following steps: first positioning an electrically conductive intermediate connection part on the capacitive element, the intermediate connection part comprising a covering plate including at least one through opening for the passing of a fluid and a peripheral skirt extending on the periphery of the covering plate and perpendicular to said covering plate, the intermediate connection part being positioned so that thefts covering plate covers the end of the capacitive element, its peripheral skirt covers a part of the side wall of the envelope, then joining the covering plate to the capacitive element in particular by welding;secondly positioning a cover comprising a covering wall on the intermediate connection part such that the covering wall covers the end of the envelope and forms one of the two bottom walls of this envelope and joining the peripheral skirt of the intermediate connection part to the side wall of the envelope and to the cover so as to allow deformation of the bottom wall relative to the intermediate connection part, in particular by gluing, brazing or welding, the covering plate of said intermediate connecting part being devoid of securing regions with the cover,these steps being performed so that the intermediate connection part is placed between the capacitive element and the cover, and so that the peripheral skirt of the intermediate connection part partly covers the side wall of the envelope.
