Energy storage cell

An energy storage cell includes a housing comprising a metallic, tubular housing with a circular opening. The energy storage cell further includes an electrode-separator assembly winding having two terminal end faces and a wound jacket, the electrode-separator assembly comprising an anode, a cathode, and a separator. The energy storage cell additionally includes an at least partly metallic contact element in direct contact with and connected to current collector by welding. The contact element comprises a circular edge and closes the terminal circular opening of the tubular housing portion in a gas- and liquid-tight manner. The contact element is or comprises a metallic membrane electrically connected to a current collector. The metallic membrane is configured to, in response to a pressure in the housing exceeding a threshold, bend such that electrical contact between the contact element and the current collector is lost.
