Abstract: A method for manufacturing an electrochemical cell first includes providing a cup-shaped housing with at least one first indentation. Thereafter, an electrode stack is placed in the housing and then, the first indentation is indented further in a direction towards the inside of the housing by a applying a force on the housing laterally to the first indentation, during which the electrode stack becomes fixed in the housing. As a result, electrode stacks can be fixed particularly easily and reliably in cup-shaped housings. An electrochemical cell is also provided.

Abstract: 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.
