Summary: | The invention relates to a cylindrical battery cell welding method which comprises the following steps: (1) performing 90-degree bending spot welding on a spot welding nickel sheet to form the cylindrical battery cell, so that the spot welding nickel sheet is L-shaped; (2) aligning the two end faces of the spot welding nickel sheet to the end faces of the battery cell A and the battery cell B respectively; (3) spot-welding and fixing one end surface of the spot-welded nickel sheet on the battery cell A; (3) after the spot welding of the battery cell A and the spot welding nickel sheet is completed, rotating the battery cell A and the spot welding nickel sheet by 90 degrees to enable the battery cell B which is originally transversely placed to rotate to the vertical direction, and then spot welding and fixing the transverse battery cell B and the other end surface of the spot welding nickel sheet; and (4) after the battery cell A and the battery cell B are respectively fixed with the spot welding nickel sheet |
