Verfahren zum Verbinden eines metallischen Ableiters an eine ein Schaumgerüst als Trägerteil enthaltende Elektrode für einen elektrochemischen Generator und bei diesem Verfahren erhaltene Elektrode

摘要

A method of bonding a metal connection onto an electrode for an electrochemical cell including a foam type substrate (2), which substrate has been filled with active material and then compressed, the method being characterized by the facts that: at least one perforation (3, 4) is formed through said electrode; a metal tongue (5) is compressed against said performation and the surrounding zone, which tongue penetrates superficially into a first face of the electrode; and said connection (11) is welded onto said metal tongue (5) through said perforation (3, 4).
