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.
