Abstract
A battery cell includes cathode electrodes including cathode electrode coatings arranged on cathode current collectors, and anode electrodes including anode electrode coatings arranged on anode current collectors. The cathode electrodes and the anode electrodes are arranged in a predetermined order in a stack. The cathode current collectors include first external tabs in a first asymmetric position and second external tabs in a second asymmetric position. The first external tabs and the second external tabs of the cathode electrodes are welded to a cathode lead tab. The anode current collectors include first external tabs in a first asymmetric position and second external tabs in a second asymmetric position. The first external tabs and the second external tabs of the anode electrodes are welded to an anode lead tab.
