Method for Manufacturing a Cylindrical Battery Cell for a Traction Battery of a Motor Vehicle, and Cylindrical Battery Cell

A method for manufacturing a cylindrical battery cell for a traction battery of a motor vehicle, in which method: an electrode coil is wound, a cathode contact region being arranged on the first end face of said electrode coil and an anode contact region being arranged on the second end face of said electrode coil opposite the first end face; the cathode contact region and the anode contact region are flattened at the end faces; a cathodic current collector plate is welded to the flattened cathode contact region; a housing cover is welded directly to the flattened anode contact region; the electrode coil is inserted into a housing cylinder; the cathodic current collector plate is electrically connected to a positive pole of the housing cylinder; and the housing cover is connected to the housing cylinder.
