  • Patent number: 11355820
    Abstract: A new weld configuration is used to obtain a robust and consistent resistance weld between the tabs of an anode current collector and the casing of an electrochemical cell. This is done by adding a resistive transferable electrode tip between at least one of the welding electrodes, preferably the movable welding electrode, and the stacked parts that are being joined together. The purpose of the transferable electrode tip is to generate a sufficient amount of heat during the welding process so that the stacked parts are joined together without adding any product functionality. In one embodiment of the present invention, the transferrable electrode tip is a stainless-steel ball, the stacked anode current collector tabs are of nickel, and the cell casing is of stainless-steel.
