Abstract: A method for joining external tabs of a battery cell to a terminal includes providing a battery cell stack; arranging a stack of external tabs of one of C cathode electrodes and A anode electrodes on a terminal; laser melting ends of the stack of external tabs; and after the laser melting, laser welding the stack of external tabs of the one of the C cathode electrodes and the A anode electrodes to the terminal.
