Abstract: A method for forming an electrochemical cell involves pressing a first contact element of a forming unit onto a first forming contact-making section of a first conductor of the cell, pressing a second contact element of the forming unit onto the second forming contact-making section of the second conductor of the cell, carrying out a forming treatment on the cell, separating the first forming contact-making section from the first conductor, and separating the second forming contact-making section from the second conductor.

Abstract: A method for forming an electrochemical cell comprising a first connector and a second connector for a battery preferably designed for use in motor vehicles which employs a forming unit comprising a first contact element and a second contact element, wherein the first connector comprises a first formation contact section designed to be disconnectable and the second connector comprises a second formation contact section designed to be disconnectable, comprising the steps of: (S1a) pressing the first contact element of the forming unit against the first formation contact section of the first connector, (S1b) pressing the second contact element of the forming unit against the second formation contact section of the second connector, (S5) implementing a forming treatment, (S6a) separating the first formation contact section from the first connector, and (S6b) separating the second formation contact section from the second connector.
