Abstract
A method for joining external tabs of a battery cell to a terminal includes providing a battery cell stack including C cathode electrodes, A anode electrodes, and S separators, where C, S and A are integers greater than one. The method includes arranging a stack of external tabs of one of the C cathode electrodes and the A anode electrodes on a terminal; and laser welding W weld segments in each of L weld locations on the stack of external tabs of one of the C cathode electrodes and the A anode electrodes to join the external tabs of the one of the C cathode electrodes and the A anode electrodes to the terminal, where W and L are integers greater than one.
