Abstract
A container for a sealed secondary cell containing an electrode plate group is provided comprising a wall forming a base () in electrically conducting material, the base comprising a peripheral portion (), a closure member portion () and a weakened portion () joining the peripheral portion () to the closure member portion and designed to rupture in the presence of an excess pressure inside the container. An electrically insulating ring member () is mounted on the peripheral portion to support the electrode plate group, and the container includes an electrically conducting flexible connection part (), electrically connected to the closure member portion () and to the electrode plate group, in which, in the presence of an excess pressure leading to rupturing of the weakened portion, the connection part guides the closure member portion to a position after rupture which is substantially parallel to its position prior to rupture.
