CONTINUOUS CURRENT COLLECTORS IN BATTERY CONFIGURATIONS

Abstract:

Battery cells according to embodiments of the present technology may include an electrode stack including a first cell segment, a second cell segment, and a third cell segment each having an anode, a cathode, and a separator positioned between the anode and the cathode. Layering of the anode and the cathode of the second cell segment may be reversed from layering of the anode and the cathode of the first cell segment and the third cell segment. The battery cells may include a cathode current collector including a conductive material extending continuously in a U-shaped pattern to extend across and in contact with the cathode of each section of the electrode stack. The battery cells may also include an anode current collector comprising a conductive material extending continuously in a U-shaped pattern to extend across and in contact with the anode of each section of the electrode stack.
