NOVELTY - The cell (1) has a rechargeable electrode assembly (2) including two electrodes for supplying electrical energy. A current conducting device (4) is electrically connected to electrodes of the electrode assembly. A cell housing (5) encloses sections of the electrode assembly and comprises housing parts (6, 6a) provided with a functional device (8) that supports release of energy from the electrode assembly to a load that is operatively connected to the electrode assembly. Support elements (7, 7a) are provided to support the functional device and formed with a metal sheet.    USE - Converter cell for use in a secondary battery (claimed) i.e. lithium ion battery, utilized in a motor vehicle and hybrid or electric vehicle. Can also be used in a stationary battery, device battery, industrial battery and starter battery.    ADVANTAGE - The cell allows the cell housing to be manufactured at a predetermined flexural rigidity such that a predetermined energy consumption capacity relative to a foreign body acts on the cell from an environment, so that mechanical stability of the cell is improved. The cell allows the support element to improve cohesion of the functional device, so that stability relative to vibrations of the cell is improved or functioning of the cell when subjected to vibrations is improved and the cell dispenses with separate, reinforcing components, and in contrast to converter cells with foil-like cell housings, thus simplifying manufacturing process and reducing manufacturing costs.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following:    (1) a method for manufacturing housing parts of a converter cell    (2) a method for manufacturing a housing assembly    (3) a method for manufacturing a converter cell.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a converter cell.    Converter cell (1)    Rechargeable electrode assembly (2)    Current conducting device (4)    Cell housing (5)    Housing parts (6, 6a)    Support elements (7, 7a)    Functional device (8)
