Claim:
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.
