Patent ID: 7972720

Claim:
A method for producing a secondary electrochemical generator, said generator comprising a container having a casing and having a cover electrically insulated from said casing and carrying a current output, and at least one electrode which is electrically connected to a connection, wherein the connection is a single piece element having a first flat portion and a second tongue portion raised into a plane forming an angle relative to a plane of said first flat portion, and wherein the method comprises a stage of electric coupling of said connection to said current output comprising the following steps: electrically connecting the first flat portion of said connection to said electrode, placing said cover on said casing in order to close said container so that an end of the tongue portion of said connection is in physical contact with said current output, and applying an electric current between said casing and said current output after said cover has reached a final closed position, so as to weld said end of said tongue portion to said current output.
