Abstract: A battery cell comprises an electrode stack including A anode electrodes with A anode current collectors. A external tabs extend from the first side of the A anode electrodes. C cathode electrodes include C cathode current collectors and C external tabs. A separator comprises a continuous sheet interleaved between the anode electrodes and the C cathode electrodes. The A external tabs of the A anode electrodes are folded along the separator on the first side of the A anode electrodes. The C external tabs of the C cathode electrodes are folded along the separator on the second side the C cathode electrodes. The electrode stack is arranged in a housing. First and second tab positioning members including first and second external lead tabs are connected to the A external tabs and the C external tabs, respectively.
