An electrochemical cell includes an electrode stack and a housing that is substantially cylindrical in shape and that holds the electrode stack. The housing has an indentation that forms a substantially flat contact area with the electrode stack. A method for producing the electrochemical cell includes inserting the electrode stack into the housing, bringing a die into contact with the housing, the die having a head with at least three contact points that come into contact with the housing, and stamping the die onto the housing to form the indentation.
