Abstract
An electrode assembly constructed of continuous anode and cathode electrodes that are overlaid in overlapping fashion and wound into a cell stack suitable for prismatic or other non-cylindrically-shaped cases. The cathode electrode strip has some regions where the electrode material is pressed to a high density and has some regions where the active material is pressed to a lower density, such that the lower density regions correspond to the bend regions in the wound cell stack.
