The invention provides a sealed organic-electrolyte cell. A spiral-wound group of electrodes have at least one alternation of negative electrode, separator and positive electrode. The cell has an enclosure made up of a cover and an end wall interconnected in a sealed manner by a side case surrounding the group. Each cover and end wall has a respective current outlet terminal and a central core around which the electrode group is spiral-wound, with an end wall and the cover being fixed to the ends thereof. The case surrounding the group is made of a combined metal-and-plastics multilayer material of a thickness that is smaller than 0.5 mm. The invention also provides a module of such cells and a battery that has at least one such module. The battery is suitable for use as the battery of an electric vehicle.
